A new study reveals that modern humans, Neanderthals, and other relatives evolved larger brains through gradual changes within each species, overturning the idea of sudden leaps in brain size. Researchers used the largest-ever fossil dataset spanning 7 million years and advanced statistical methods to reconstruct brain size evolution.
