Larger brain, smaller face: Human evolution took a different course than previously though

A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size of the face and jaw—may be far less attributable to directed natural selection than scientists have
