The Evolution-Creationism Controversy as a Test Case in Equal Time and Free Speech

A book chapter for The Palgrave Handbook of Philosophy and Public Policy (December 26, 2018), edited by David Boonin.

During the second week of March, 1837, barely a year and a half after circumnavigating the globe in the H.M.S. Beagle, Charles Darwin met with the eminent ornithologist John Gould, who had been studying Darwin’s Galápagos bird specimens. With access to museum ornithological collections from areas of South America that Darwin had not visited, Gould corrected a number of taxonomic errors Darwin had made, such as labeling two finch species a “Wren” and “Icterus”, and pointed out to him that although the land birds in the Galápagos were endemic to the islands, they were notably South American in character.

According to the historian of science Frank J. Sulloway, who carefully reconstructed Darwin’s intellectual voyage to the discovery of the theory of evolution by means of natural selection, Darwin left the meeting with Gould convinced “beyond a doubt that transmutation must be responsible for the presence of similar but distinct species on the different islands of the Galápagos group. The supposedly immutable ‘species barrier’ had finally been broken, at least in Darwin’s own mind.”1 That July Darwin opened his first notebook on Transmutation of Species. By 1844 he was confident enough to write in a letter to his botanist friend and colleague Joseph Hooker: “I was so struck with distribution of Galapagos organisms &c &c, & with the character of the American fossil mammifers &c &c, that I determined to collect blindly every sort of fact which cd bear any way on what are species.” Five years at sea and nine years at home pouring through “heaps” of books led Darwin to admit: “At last gleams of light have come, & I am almost convinced, (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable.”2

Like confessing a murder. How could a solution to a technical problem in biology, namely the immutability of species, generate such angst in its discoverer? The answer is obvious: if new species are created naturally instead of supernaturally, there’s no place for a creator God. No wonder Darwin waited twenty years before publishing his theory, and he would have waited even longer had he not rushed into print for priority sake because the naturalist Alfred Russel Wallace had sent Darwin his own theory of evolution in 1858, the year before Darwin published On the Origin of Species.3 And no wonder it took some time for Darwin to convince others of the theory’s veracity. The geologist Charles Lyell, a close friend and colleague of Darwin who groomed him into the world of British science and whose geological works Darwin read on the Beagle, withheld his support for a full nine years, and even then pulled back from fully embracing naturalism, leaving room for providential design underlying the entire natural system. The astronomer John Herschel sniffed at natural selection, calling it the “law of higgledy-piggledy.” In a review in the popular Macmillan’s Magazine, the statesman and economist Henry Fawcett spoke of a great divide created by Darwin’s book: “No scientific work that has been published within this century has excited so much general curiosity as the treatise of Mr. Darwin. It has for a time divided the scientific world with two great contending sections. A Darwinite and an anti-Darwinite are now the badges of opposed scientific parties.”4

Darwinites and anti-Darwinites. After a century and a half there is now overwhelming consensus within the scientific community that evolution happened and that natural selection is the driving force behind it. Among scientists, there are only Darwinites. Publicly, however, the picture is disturbingly divided, especially along political and religious lines, where the anti-Darwinites have captured a sizable portion of the populace. A 2005 Pew Research Center poll, for example, found 42 percent of Americans holding strict creationist views that “living things have existed in their present form since the beginning of time.” The survey also found that 64 percent said they were open to the idea of teaching creationism in addition to evolution in public schools, while 38 percent said they think evolution should be completely replaced by creationism in biology classrooms. Most alarmingly, a sizable 41 percent believe that parents, rather than scientists (28 percent) or school boards (21 percent) should be responsible for teaching children about the origin and evolution of life.5 More recent polling data found similar percentages of belief in creationism and skepticism about evolution. In a 2014 Gallup poll 42 percent of Americans said that “God created humans in present form” while 31 percent said “Humans evolved, with God guiding.” There was a slight uptick to 19 percent of Americans who agreed that “Humans evolved, but God had no part in the process,” but that was at least a significant gain from the paltry 9 percent in 1982.

None of this polling data should matter. Truth in science is not determined vox populi. It shouldn’t matter how many people support one or another position. As Einstein said in response to a 1931 book skeptical of relativity theory titled A Hundred Authors Against Einstein, “Why one hundred? If I were wrong, one would have been enough.”6 A theory stands or falls on evidence, and there are few theories in science that are more robust than the theory of evolution. Arguably the most culturally jarring theory in the history of science, the Darwinian revolution changed both science and culture in at least five ways:

  1. The static creationist model of species as fixed types was replaced with a fluid evolutionary model of species as ever-changing entities.
  2. The theory of top-down intelligent design through a supernatural force was replaced with the theory of bottom-up natural design through natural forces.
  3. The anthropocentric view of humans as special creations above all others was replaced with the view of humans as just another animal species.
  4. The view of life and the cosmos as having design, direction, and purpose from above was replaced with the view of the world as the product of bottom-up design through necessitating laws of nature and contingent events of history.
  5. The view that human nature is infinitely malleable and primarily good, or born in original sin and inherently evil, was replaced with the view of a constraining human nature in which we are both good and evil.7

When he first heard Darwin’s theory, the man who would earn the moniker “Darwin’s Bulldog” for his fierce defense of evolution, Thomas Henry Huxley, called Darwin’s On the Origin of Species “the most potent instrument for the extension of the realm of knowledge which has come into man’s hands since Newton’s Principia.”8 A century later the Harvard evolutionary biologist Ernst Mayr opined, “it would be difficult to refute the claim that the Darwinian revolution was the greatest of all intellectual revolutions in the history of mankind.”9 And in the memorable and oft-quoted observation by the evolutionary theorist Theodosius Dobzhansky, “Nothing in biology makes sense except in the light of evolution.”10 If the theory of evolution is so proven and profound, why doesn’t everyone accept it as true?

Why People Do Not Accept Evolution

It is evident that there are a number of extra-scientific variables that factor into the beliefs people hold about scientific theories, and in this case additional polling data show who is more or less likely to accept evolution based on their religious and political attitudes. In the 2014 Gallup Poll mentioned above, 69 percent of Americans who attend religious services weekly embrace creationism over evolution, compared to only 23 percent of those who seldom or never attend religious services.11 A 2013 Pew Research Center survey found that white evangelical Protestants are more likely to believe that humans have existed in their present form since the beginning of time at 64 percent, compared to half of black Protestants and only 15 percent of white mainline Protestants.12 A 2017 Gallup Poll found that 57 percent of those with no religious preferences agreed with the statement “Humans evolved, God had no part in process” compared to only 6 percent of Protestants and 11 percent of Catholics, and only 1 percent of those who attend church weekly agreed with this statement, compared to 35 percent who rarely attend church.13

The underlying foundation behind this religious-based skepticism of evolution may be traced back to the early 20th century when anti-evolution legislation was sweeping southern states, most famously Tennessee. At the climax of the 1925 Scopes “monkey” Trial in Dayton, William Jennings Bryan, testifying on behalf of the prosecution against a young biology teacher name John T. Scopes, prepared a final statement summarizing what he understood to be what was really at stake in the trial. The judge determined that Bryan’s speech was irrelevant to the case—the same ruling he made against the defense when they called on evolutionary biologists as expert witnesses—so it was published posthumously (Bryan died two days after the trial ended) as Bryan’s Last Speech: The Most Powerful Argument Against Evolution Ever Made.14 The most telling summation of the anti-evolution position in Bryan’s view was as follows: “The real attack of evolution, it will be seen, is not upon orthodox Christianity or even upon Christianity, but upon religion—the most basic fact in man’s existence and the most practical thing in life. If taken seriously and made the basis of a philosophy of life, it would eliminate love and carry man back to a struggle of tooth and claw.” This is what troubles people about evolutionary theory and leads them to doubt its verisimilitude, not the technical details of the science. The syllogistic reasoning goes like this:

  1. The theory of evolution implies that there is no God.
  2. Without a belief in God there can be no morality or meaning.
  3. Without morality and meaning there is no basis for a civil society.
  4. Without a civil society we will be reduced to living like brute animals.

This sentiment was expressed by the Intelligent Design theory supporter Nancy Pearcey in a briefing before a House Judiciary Committee of the United States Congress, when she quoted from a popular song urging “you and me, baby, ain’t nothing but mammals so let’s do it like they do on the Discovery Channel.” She went on to claim that since the U.S. legal system is based on moral principles, the only way to generate ultimate moral grounding is for the law to have an “unjudged judge,” an “uncreated creator.”15 The neo-conservative social commentator Irving Kristol was even more bleak in a 1991 statement: “If there is one indisputable fact about the human condition it is that no community can survive if it is persuaded—or even if it suspects—that its members are leading meaningless lives in a meaningless universe.”16

In an attempt to distance themselves from “scientific creationists,” Intelligent Design theorists have emphasized that they are only interested in doing science. According to the prominent ID proponent William Dembski, for example, “scientific creationism has prior religious commitments whereas intelligent design does not.”17 This is disingenuous. On February 6, 2000, Dembski told the National Religious Broadcasters at their annual conference in Anaheim, California: “Intelligent Design opens the whole possibility of us being created in the image of a benevolent God…. The job of apologetics is to clear the ground, to clear obstacles that prevent people from coming to the knowledge of Christ. … And if there’s anything that I think has blocked the growth of Christ as the free reign of the Spirit and people accepting the Scripture and Jesus Christ, it is the Darwinian naturalistic view.”18 In a feature article in the Christian magazine Touchstone, Dembski was even more succinct: “Intelligent design is just the Logos theology of John’s Gospel restated in the idiom of information theory.”19

The sentiment was echoed by one of the fountainheads of the modern Intelligent Design movement, Phillip Johnson, at the same National Religious Broadcasters meeting at which Dembski spoke: “Christians in the twentieth century have been playing defense. They’ve been fighting a defensive war to defend what they have, to defend as much of it as they can. It never turns the tide. What we’re trying to do is something entirely different. We’re trying to go into enemy territory, their very center, and blow up the ammunition dump. What is their ammunition dump in this metaphor? It is their version of creation.”20 Johnson was even blunter in 1996: “This isn’t really, and never has been, a debate about science…. It’s about religion and philosophy.”21 In his book The Wedge of Truth, Johnson explained: “The Wedge of my title is an informal movement of like-minded thinkers in which I have taken a leading role. Our strategy is to drive the thin end of our Wedge into the cracks in the log of naturalism by bringing long-neglected questions to the surface and introducing them to public debate.” This is not just an attack on naturalism—it is a religious war against all of science. “It is time to set out more fully how the Wedge program fits into the specific Christian gospel (as distinguished from generic theism), and how and where questions of biblical authority enter the picture. As Christians develop a more thorough understanding of these questions, they will begin to see more clearly how ordinary people—specifically people who are not scientists or professional scholars—can more effectively engage the secular world on behalf of the gospel.”22 The new creationism may differ in the details from the old creationism, but their ultimate goals run parallel. The veneer of science in the guise of Intelligent Design theory is there to cover up the deeper religious agenda.

Equal Time and Free Speech

This volume relates to public policy. Engrained in the American public psyche is the sense of fair play for all ideas and free speech for everyone. What’s wrong with giving equal time to evolution and creationism and letting the people decide for themselves? This is, in fact, what has become known as the “equal time” argument proffered by proponents of “creation science” in the 1980s and “intelligent design” in the 1990s. It’s an argument that appeals to fair-minded people, but that cannot be put into practice in public schools, which is where the evolution-creation battles have been fought. The problem is that there are at least ten different positions one might take on the creation-evolution continuum, including:

Flat Earthers, who believe that the shape of the earth is flat and round like a coin, which some believers contend has a biblical basis.

Geocentrists, who believe that the earth is spherical but that the planets and sun revolve around it, also believed to be grounded in Genesis scriptures.

Young-Earth Creationists, who believe that the earth and all life on it was created within the last ten thousand years.

Old Earth Creationists, who believe that the earth is ancient and microevolution may alter organisms into different varieties of species, but that all life was created by God, and that species cannot evolve into new species.

Gap Creationists, who believe that there was a large temporal gap between Genesis I:1 and I:2, in which a pre-Adam creation was destroyed, after which God recreated the world in six days; the time gap between the two separate creations allows for an accommodation of an old Earth with the special creation.

Day-Age Creationists, who believe that each of the six days of creation represents a geological epoch, and that the Genesis sequence of creation roughly parallels the sequence of evolution.

Progressive Creationists, who accept most scientific findings about the age of the universe and that God created “kinds” of animals sequentially; the fossil record is an accurate representation of history because different animals and plants appeared at different times rather than having been created all at once.

Intelligent Design Creationists, who believe that the order, purpose, and design found in the world is proof of an intelligent designer.

Evolutionary Creationists, who believe that God used evolution to bring about life according to his foreordained plan from the beginning.

Theistic Evolutionists, who believe that God used evolution to bring about life, but intervenes at critical intervals during the history of life.23

If equal time were granted to all of these positions, along with the many other creation myths from diverse cultures around the world, when would students have time to learn science? Given limited time and resources, and the ever-expanding body of scientific knowledge that students in a 21st century society simply must learn for our nation to stay relevant economically, such ideas have no place in science classrooms where curricula are determined by the consensus science of the field, not polls on what the public believe. The place for introducing these ideas is in courses on history, cultural studies, comparative mythology, and world religions. In any case, as far as public policy is concerned, creationists have lost all major court cases of the past half-century—most notably Epperson v. Arkansas in 1968, McLean v. Arkansas Board of Education in 1982, Edwards v. Aguillard in 1987, and Kitzmiller et al. v. Dover in 2005—so legal precedent means that the chances of creationists or Intelligent Design proponents gaining access to public school science classrooms through legislation is nil.24 Consensus science cannot be legislated by fiat from the top down. In the 1920s when evolutionary theory was not widely accepted and politically connected religious groups were successful in passing anti-evolution legislation making it a crime to teach Darwin’s theory in public schools, the noted attorney and civil liberties defender Clarence Darrow made this case against the censorship of knowledge in the Scopes case:

If today you can take a thing like evolution and make it a crime to teach it in the public school, tomorrow you can make it a crime to teach it in the private schools, and the next year you can make it a crime to teach it in the hustings or in the church. At the next session you may ban books and the newspapers. Soon you may set Catholic against Protestant and Protestant against Protestant, and try to foist your own religion upon the minds of men. If you can do one you can do the other. Ignorance and fanaticism is ever busy and needs feeding. Always it is feeding and gloating for more. Today it is the public school teachers, tomorrow the private. The next day the preachers and the lecturers, the magazines, the books, the newspapers. After awhile, your honor, it is the setting of man against man and creed against creed until with flying banners and beating drums we are marching backward to the glorious ages of the sixteenth century when bigots lighted fagots to burn the men who dared to bring any intelligence and enlightenment and culture to the human mind.25

In America, the First Amendment protects the right of citizens to express their opinions on anything they like, no matter how crazy, conniving, evil, or extreme. You are free to doubt the single-bullet theory in the JFK assassination, the real cause of the death of Princess Diana, the Apollo moon landing, the existence of God, the divinity of Jesus, the authenticity of the Quran, the prophetic nature of Moses or Muhammad, al Qaeda’s role in 9/11, and even the President’s birthplace. No matter how much one may dislike someone else’s opinion—even if it is something as disturbing or potentially disruptive as denying that the Holocaust happened or that some people may not be as successful because of innate racial or gender differences—that opinion is protected by the First Amendment. Not everyone thinks such freedom is good for a safe civil society. In particular, and paradoxically given the fact that the free speech movement began at U.C. Berkeley in the 1960s, the past several years have seen campuses around the country erupt in flames over these charged issues, issuing lists of micro-aggressions that might offend people, trigger warnings about books that might upset readers, safe spaces to go to for protection from dangerous ideas, and the dis-invitation of speakers who might espouse ideas different from the majority of people in the audience.26 Shouldn’t we protect people from speech that might be hateful and thus harmful? No. Here are eight reasons why.

  1. Who decides which speech is acceptable and which is unacceptable? You? Me? The majority? The control of speech is how dictatorships and autocracies rule. We must resist the urge to control what other people say and think.
  2. What criteria are used to censor certain speech? Ideas that I disagree with? Thoughts that differ from your thoughts? Anything that the majority determines is unacceptable? That’s another form of tyranny, a tyranny of the majority.
  3. We might be completely right but still learn something new.
  4. We might be partially right and partially wrong, and by listening to other viewpoints we might stand corrected and refine and improve our beliefs.
  5. We might be completely wrong, so hearing criticism or counterpoint gives us the opportunity to change our minds and improve our thinking. No one is infallible. The only way to find out if you’ve gone off the rails is to get feedback on your beliefs, opinions, and even your facts.
  6. Whether right or wrong, by listening to the opinions of others we have the opportunity to develop stronger arguments and build better facts for our positions.
  7. My freedom to speak and dissent is inextricably tied to your freedom to speak and dissent. If I censor you, why shouldn’t you censor me? If you silence me, why shouldn’t I silence you? Once customs and laws are in place to silence someone on one topic, what’s to stop people from silencing anyone on any topic that deviates from the accepted canon?

There are exceptions to the purely civil libertarian case for free speech, of course, most famously Justice Oliver Wendell Holmes’ concerns about false fire warnings and crowded theaters, which was wrongly applied to the ill-conceived idea that “hate speech” might incite people to violence, applied as it was to a group of Yiddish-speaking pacifists who objected to America’s involvement in the First World War. And, of course, you are not free to spread lies about someone that damages their reputation, safety, or income. But never in history have a people been so free to speak their mind, and from that freedom emerges the truth, for the only way to know if your idea is wrong is to allow others to critique it.

Science and Society

That principle—the freedom to participate in the dialogue that the philosopher Karl Popper called “conjecture and refutation”—is at the heart of the scientific method.27 The reason we need critical feedback from others is that our brains come equipped with a set of cognitive heuristics—rules of thumb, or shortcuts—that help us navigate through the buzzing blurring confusion of information coming in through our senses. These heuristics are also known as cognitive biases because they often distort our percepts to fit preconceived concepts. These cognitive biases are part of a larger process called “motivated reasoning,” in which no matter what belief system is in place—religious, political, economic, or social—they shape how we interpret information that comes through our senses and motivate us to reason our way to finding the world to be precisely the way we wish it were. As I argue in The Believing Brain, our beliefs are formed for a variety of subjective, emotional, psychological, and social reasons, and then are reinforced through these belief confirmation heuristics and justified and explained with rational reasons.28 The confirmation bias, the hindsight bias, the self-justification bias, the status quo bias, the sunk-cost bias, the availability bias, the representative bias, the believability bias, the authority bias, and the consistency bias are just a few of the many ways we distort the world.

It is not so much that scientists are trained to avoid these cognitive biases as it is that science itself is designed to force you to ferret out your errors and prejudices because if you don’t someone else will, often with great glee in a public forum, from peer-review commentary to social media (where all pretensions to civil discourse are stripped away). Science is a competitive enterprise that is not for the thin-skinned or faint of heart. Most ideas that people come up with are wrong. That is why science is so cautious about tossing aside old ideas that have already survived the competitive marketplace, and why scientists tend to dismiss out of hand new ideas that threaten a tried-and-true research paradigm, especially before the revolutionary theory has been properly vetted by professionals in the field. That process of generating new ideas and introducing them to your peers and the public where they can be skeptically scrutinized in the bright light of other minds is the only way to find out if you’ve come up with something true and important or if you’ve been immersed in self-deception. Evolutionary scientists have gone through this rigorous process for over a century and a half and the theory has emerged all the stronger for it. Creationists, by contrasts, have actively avoided this scientific scrutiny and as a result have been marginalized to the point of irrelevance.

Such is the fate of most ideas—many are called, few are chosen. Science works because it is premised on debate and disputation, conjecture and refutation, and especially free and open inquiry, which together override our many cognitive biases that blind us individually to our errors, but collectively allow us to progress to an ever deeper and broader understanding of nature. As the physicist and former scientific director of the Manhattan Project that built the first atomic bombs, J. Robert Oppenheimer, reflected on the limits of science: “There must be no barriers to freedom of inquiry. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors.” Reflecting on the history of science and extrapolating to wider spheres, Oppenheimer added: “Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.”29

24 Comments to “Free to Inquire”

  1. Joseph Says:

    Terrific piece, Michael. Pardon my literate pedantry but you ‘pore’ through books, not ‘pour’, unless perhaps you wish to apply a liquid…

  2. Kevin McDonald Says:

    This is a superb, concise statement crisply covering the range of issues raised. Although billed as just a book chapter, it is an excellent stand-alone summary of the wide range of viewpoints and arguments raised since Darwin published his paradigm-changing masterpiece in 1859. I will make productive use of this essay in those future debates which are certain to continue. Thank you Michael Shermer!

  3. Steve O'Kane Says:

    Hi Michael,

    Is it possible to obtain a PDF of “The Evolution-Creationism Controversy as a Test Case in Equal Time and Free Speech”? I’d love to use this in my “Evolution, Ecology, and the Nature of Science” course at the University of Northern Iowa.


  4. Bad Boy Scientist Says:

    Thank you Dr Mike for being willing to fight the good fight in these matters and write such illuminating articles for the rest of us. I do not have the stomach to argue with Astrologers, UFOlogists, Moon Landing Deniers, and Creationists. This is partially because so many of them employ – not mere logical fallacies – nor even intellectually dishonest arguments – they just get into ‘pissing contests.’

    It’s good that we have people like Dr Mike who will put on hip waders to clean up after Gish Gallops.

  5. Simon Says:

    “No. Here are eight reasons why. ”
    Sorry to nitpick but the list only reaches number seven.

  6. Jenny H Says:

    If you are going to have ‘equal time’ for religious views, then you must include ALL religions — including Native Religions Shinto, Tao, Confucism, Hinduism, Buddhist and Sikh, as well as the ‘Biblical’ religions. You must also give time to those religious sects that do NOT believe in “Creationism’. And IF these people declare that their Creationism is not based on religions itself, then we should probably also give equal time to Flat Earthers, Spiritualists, Necromancers and believers in visitors from outer space.
    Christianity is not the sole religion in this world.

  7. Jenny H Says:

    Personally I think that the solution is to teach a good
    Comparative Religion Course in Schools. Not asking anybody to ‘believe’ in any religion, but to know about other religions and their beliefs. Some acquaintance with the literature of different religions and the histories of these texts.
    As well as the distribution of believers in the various religions across the world.
    A study of ‘religion’ in incredibly fascinating!

  8. Henry Adam Says:

    As a Brit, I ask the question – on free speech in the USA, is it allowable to be a holocaust denier?

  9. DJKrause Says:

    I have never understood how historic christianity, a religion which in virtually all its forms condemns the vast majority of humans to an eternity of torment (and in its most intellectual versions, makes this happen solely because of god’s predestinating will) can serve as a basis for morality.

  10. Gary S Says:

    I agree with Jenny S(I think Dan Dennett proposed a similar but more formal idea), that schools should teach comparative religion. It was really my girlfriend’s study of CR in University that made both of us question the ‘faith’ we had both been indoctrinated with. Of course, if the religious faithful think that such enlightenment will cause their children to think independently, they will resist any such move via School Boards, just as they have done with the teaching of Evolution.

    @Henry Adam, as a Brit living in the US, Yes, free speech allows one to be a holocaust denier in the US(or a flat-Earther, or Apollo-mission denier). But you won’t get much of an outlet for such views on most mainstream(fact-based) media, but there are plenty of right-wing outlets that’ll let you espouse such views. “Sad, really sad”, has a very real meaning over here for moderates and left-wingers alike here.

  11. Valkyrie Ziege Says:

    ; We have a proper legal system, that religions use to defend themselves after causing more problems, as usual, including sexual abuse, usually of children, deaths of followers, and non-believers.
    There isn’t any moral high ground in religions. Why should intelligent, emotionally mature people have to tolerate being threatened, sexually assaulted, and/or murdered, by those claiming their invisible friend in the sky is the most powerful, and gave them permission to be violent, and aggressive.
    “Violence is the last refuge of the incompetent”. – Isaac Asimov

    As to free speech issues, we should be able to openly examine the events of world war II without fear of, condemnation, loss of job, loss of social standing, being sentenced to time in jail, or prison, and financial losses. The truth doesn’t have anything to fear.

    Great Article. thanks.

  13. Jack Kilmon Says:

    Every man carries the evidence of evolution around for all to see when shirts are removed. Males evolved from females. Otherwise, where did those nipples (organs for suckling young) come from? In short and figuratively, “Eve” came FIRST!
    Great article.

  14. Planetary Scientist Says:

    Thank you, thank you, Michael, for providing us with such a succinct summary of the bases for the variety of opinions on these topics. As you mention, this is not about evolution only, it is about science as a whole. I wish I’d read this five days ago, before I was sitting between two born-agains on an airliner. The References section alone is a gold mine, and the excerpts you’ve distilled from those references make it even more valuable and efficient.

    One edit I would make: in the characterization of the Intellegent Design Creationists, “…who believe that the order, purpose, and design found in the world is proof of an intelligent designer,” I would change that to, “…who believe that the order, purpose, and design *they find* in the world is proof of an intelligent designer.” That “order, purpose, and design” is not universally recognized as fact, so the wording should reflect that contingency.

    (Just started reading). ” Five years at sea and nine years at home pouring through “heaps” of books led Darwin to admit….”
    I hope the books didn’t get too wet as Darwin “poured” over them.

  16. OldNassau'67 Says:

    I suggest following the grandfather’s last advice to the unnamed narrator of Ralph Ellison’s Invisible Man: “Live with your head in the lion’s mouth. I want you to overcome ’em with yeses, undermine ’em with grins, agree ’em to death and destruction, let ’em swoller you till they vomit you or bust wide open.”

    To those who want equal time to refute Darwin: Yes, yes. Right on! Should we start with Brahmanda (Cosmic Egg) Universe, followed by
    Anaxagoras’ tiny fragments coalesced by “nous”? The Hindu’s universe, cyclically created and destroyed, divided into four epochs or Yuga, currently the Kali Yuga. T he Iroquois’ Great Turtle?

    For life itself, maybe Miler-Urey’s electric spark? Cairn-Smith’s compounds embedded in clay? The Australian aboriginal’s Wandjina, the creator, who brought forth ancestors from within the earth and over the seas, and life began.

    Denying ID’er’s or Creationists appeals to their sense of martyrdom. Better to turn their own demand of equal time around on them.

  17. Gerald McDonald Says:

    If evolution were truly based upon science, why then does it contradict what has been observed for thousands of years. This is the fact that for thousands of years, no observation has ever been made where one kind of organism has ever reproduced any other kind of organism. Bacteria have only produced bacteria. Dogs have only produced dogs.
    Where has it been shown that there was any first ever single kind of organism that made all the other kinds of organisms. We don’t see this in the history of this planet. In fact even the supposed “missing link” would not have produced anything other than what it was. This is what we have seen for thousands of years. Not that one kind of organism produced all others.

  18. Paul Berg Says:

    Cmon, Gerald, do some research. There have been lots of missing links found. There is also a pretty clear line from dinosaurs to birds, and from ape ancestors to humans (no, we are are not descended from any modern apes–both they and us are descended from the same source). We have badly designed parts of our bodies left over from evolution working from what our ancestors had, and many species have vestigal and useless leftovers of their past.
    And yes, in our time, there has been no radical change from one species to another–although I suspect if you (or I) researched, we would find isolate breeding populations in places that some woyld consider species-specific. A good starting point might be deciding on a definition of species (lots of big arguments here). I mean, I look at a Dachsund and a St. Bernard, and I find it hard to believe they’re the same species, and that is a change “in our time”.
    In our time-but as you said, “thousands of years”. A thousand is a drop in the bucket of time. Think of millions of years, tens of millions, hundreds of millions. thousands of years fairly homogenous setting (no masjor disasters or climate alterations except species extinctions. Hmm… wonder if Climate Change is going to lead to species change in the next few hundred thousand years. Because the human species hasn’t been advanced enough and lived long enough to see species change. Research this question–on time and species change and hostile environments– to learn more.
    Back to research. For an easy start, begin with science populizers: read all of Stephen Gould and Richard Dawkins books. Buy them and scribble in the margins where you find errors. (that’s what I did with von Daniken’s UFO books in my Junior High years). The Google for more background and read, read, read.
    You can take classes in evolution and evolutionary psychology (talk to universities about auditing classes), and discuss your concerns with the teachers one-on-one (NOT in class–most classes are not for debates about the basis of the class). If you want to disagree with something, learn it before you argue against it.
    By this time, you should know enough to write some intelligent articles on the subject, and be able to debate the issues without opponents snickering over “your lack of basic knowledge.”
    So go learn. Hope to hear more from you and debate intelligently in a few years.

    It appears that new species are created through mutations. Such mutations are usually dominant, which means that they can easily spread to the entire population quite quickly. Since most mutations are detrimental, they can easily be eliminated from the population .

    It has been shown that Neanderthal Man evolved from our same ancestors, but they had become a different species by the time that another wave of people left Africa. The Neanderthals appeared to have evolved to suit their new environment, and that the later arrivals were still able to interbreed with them in order to gains some of the advantages that hundreds of thousands of years had conferred on the Neanderthals.
    Horses and donkeys are separate species, but can interbreed to produce mules or hinnies. Their offspring are, of course, sterile, as the majority of the human/Neanderthal cross would have been, but every so often one individual can reproduce with one or the other of the parent species.
    In school I learned about a number of frog populations living along the east coast of the United States. Each group can breed with the groups immediately north and south of their own, but those at the extremes cannot. The definition of species is therefore hard to establish.

  21. Steven T. Says:

    An excellent piece, Michael, this quite neatly summarizes the difference between fact-based scientific inquiry and opinion. I hope this gets wide circulation by science instructors, as it is simply not enough to present students with information when they don’t know how to process it.

    That said, I have one question and a comment.

    The question concerns how acceptance of evolution and natural selection may have changed over the years, particularly since the end of WWII, and even more particularly since around 1970. As anyone who has been paying attention knows, a very large amount of money has been spent by a very small number of people over the last 45-50 years with the intent of changing the terms, range and content of normal public discourse. Has this impacted the acceptance of science? By how much? Have there been ups and downs? Are there regional differences? If someone hasn’t looked into this yet, perhaps someone should.

    The comment concerns the question of free speech. While I agree that government must never be used to suppress speech, even extremely unpopular and hateful speech, we have a situation now where mass rallies at which suggestions of violence are wildly cheered, where widely broadcast radio and TV programs wink and nudge their audiences in the direction of violence, and where actual fascists march in the streets, quiet debate may be a vastly insufficient response. We do not need an American Kristallnacht. That may seem rather over the top now, but what if this continues for another decade? What then?

  22. Paul Braterman Says:

    Henry Adam, it is perfectly legal in the UK (though not in Germany or Austria) to deny the Holocaust, provided one does not commit hate speech in the process.

    Michael Shermer, not only Lyell, but Darwin himself, left “room for providential design underlying the entire natural system”. This from his autobiography:

    Another source of conviction in the existence of God, connected with the reason and not with the feelings, impresses me as having much more weight. This follows from the extreme difficulty or rather impossibility of conceiving this immense and wonderful universe, including man with his capacity of looking far backwards and far into futurity, as the result of blind chance or necessity. When thus reflecting I feel compelled to look to a First Cause having an intelligent mind in some
    degree analogous to that of man; and I deserve to be called a Theist.”

    Although he back-tracks, for an interesting reason:

    This conclusion1 was strong in my mind about the time, as far as I can remember, when I wrote the Origin of Species; and it is since that time that it has very gradually with many fluctuations become weaker. But then arises the doubt—can the mind of man, which has, as I fully believe, been developed from a mind as low as that possessed by the lowest animal, be trusted when it draws such grand conclusions? May not these be the result of the connection between cause and effect which strikes us as a necessary one, but probably depends merely on inherited experience? ” Pages 92-93

  23. Rev BIlly Says:

    All living things are subject to mutagenesis, which may be caused from X-rays, ionization from radioactive elements, and certain chemicals. These effects are inevitable since the planet earth is constantly subject to bombardment from beyond our little rocky world. Therefore, mutations occur with regularity and, sometimes are beneficial and sometimes are not. Changes in chromosomes and genes result and serve to create physical changes in all organisms. That is a well-known fact observed from everyday science processes. DNA studies show that the changes are continuing with every new generation of offspring.

    The important thing to note here is that the changes are visible in “material”, not spiritual entities. Ovid called this “metamorphosis”. Truth does not hurt – unless it ought to.

    People who don’t want to accept this “fact of life” show that they are brainwashed in whatever “beliefs” (imaginations of the mind) they have decided to hold. As someone has said: “Science does not care what you think” in exactly correct. If a person does not wish to educate her/him-self through research and study, their statements are only opinions and really have no substance. As we all now know, as Dr. Shermer points out, we all have many biases that we have learned over our life which cloud our thinking. I call these “axes to grind” that helps us to deny the validity of others who have studied and found unbiased validity in their scientific work, work that has been verified by other scientists. Good examples today are those so-called “science-deniers” who have something to gain by not using scientific studies and results in order to help them take advantage of others and as an excuse to destroy the environment.

    The definition of Faith is “That which we imagine to be true that which we cannot prove”
    -Dan Brown
    The definition of “imagine” is “To form an image in our mind” – no rigor involved.

    Excellent review Dr. Shermer.

  24. Selden Deemer Says:

    Fair play for all ideas and free speech for everyone should not apply to things that are demonstrably false. You give a good list of such fallacies, to which I would add alchemy vs chemistry and astrology vs astronomy or whether or not Holocaust of jews in WWII actually occurred.

    I had the misfortune to engage in an online discussion with a flat earther around the time of the 2017 solar eclipse. He was convinced I was going to hell; I was convinced he was an idiot. The discussion changed neither of our opinions.

    There is simply no reasoning with these people. They are free to speak whatever nonsense they wish, but should not be given equal time in the press or in our educational system.
