These are just two of the many hyped headlines that appeared last September in response to a paper purporting the discovery, in a cave in South Africa, of a new species by paleoanthropologist Lee R. Berger of the University of the. There were reasons for skepticism from the get-go.

The age of the fossils is undetermined, and it is not yet known where in the hominin lineage the fossils fit. Their hands, wrists and feet are similar to small modern humans, and their brain volume is closer to that of the small-brained australopithecines, like Lucy. Researchers are debating whether these and other traits constitute a new species or a variation on an existing species. Instead of publishing in Science or Nature, the prestigious journals in which major new fossil human finds are typically announced, the authors unveiled their discovery in eLIFE, an open-access online journal that fast-tracks the peer-review process. And instead of meticulously sorting through the 1,550 fossils (belonging to at least 15 individuals) for many years, as is common in paleoanthropology, the analysis was published a mere year and a half after their discovery in November 2013 and March 2014.*

What triggered my skepticism, however, was the scientists’ conjecture that the site represents the earliest example of “deliberate body disposal,” which, as the media read between the lines, implies an intentional burial procedure. This, they concluded was the likeliest explanation compared with four other hypotheses. (continue reading…)
