It looks like 2017 could become some kind of genuine annus horribilis for the established scientific consensus on human evolution.
In 1982, paleontologists Niles Eldredge and Ian Tattersall noted that it is a “myth that the evolutionary histories of living beings are essentially a matter of discovery.”
Some scientists hoped that H. naledi would prove to be the fossil to bridge an evolutionary gap.
So far, Homo naledi reminds me of other hominin fossils whose “transitional” or “ancestral” status ultimately went belly up.
