The brief
A new study is examining the evolutionary drivers of encephalization and facial reduction in the genus Homo. The research suggests that human evolution may have followed a different course than previously believed, specifically questioning the reasons behind the increase in brain size.
Coverage from Nature, New Scientist, Phys.org, and Tovima emphasizes that long-held assumptions about human evolution are being challenged. New Scientist specifically notes that human brains may have grown larger without a particular reason.
Future focus remains on the specific drivers of encephalization and the processes that led to the reduction of the human face as detailed in the Nature study.
