Quoted: John Hawks, a palaeontologist at the University of Wisconsin – Madison, voiced similar doubts: “Can we really use a small part of the skull like this to recognise our species?” he said. “The storyline in this paper is that the skull is more rounded in the back, with more vertical sides, and that makes it similar to modern humans. I think that when we see complexity, we shouldn’t assume that a single small part of the skeleton can tell the whole story.”
