A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly dependent on increases in prenatal oestrogen - revealed by looking at the ...

Recent research challenges the idea that natural selection favored larger human brains. Scientists analyzed fossil skulls and found neutral evolution best explains brain size changes. This suggests ...
