For most of human evolution, the story of the brain seemed to move in one direction. It got bigger. That long rise is still there in the fossil record. But a new analysis argues that the trend did not ...

A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains. Boys with finger-length patterns linked to higher estrogen exposure before birth ...

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — a ...

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 estrogen—revealed by looking at the length ...

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 ...

Scientists have identified a 442-letter DNA sequence that may have contributed to human brain evolution. The sequence appears to influence neuron growth and the balance of different brain cell types.

A groundbreaking study reveals that the expansion of the primate neocortex may be linked to enhanced visual processing rather than an independently growing frontal lobe, shedding light on the ...
