Modern human-like brains evolved comparatively late in the genus Homo and long after the earliest humans first dispersed from Africa, according to a new study.
By analyzing the impressions left behind by the ancient brains that once sat inside now fossilized skulls, the authors discovered that the brains of the earliest Homo retained a primitive, great ape-like organization of the frontal lobe.
The findings challenge the long-standing assumption that human-like brain organization is a hallmark of early Homo and suggest that the evolutionary history of the human brain is more complex than previously thought.

- 47Modern humans are fundamentally different from our closest living relatives, the great apes: We live on the ground, walk on two legs and have much larger brains. The first populations of the genus Homo emerged in Africa about 2.5 million years ago. They already walked upright, but their brains were…
