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 ...

Human newborns arrive remarkably underdeveloped. The reason lies in a deep evolutionary trade-off between big brains, bipedalism and the limits of motherhood.

Researchers have found a link between prenatal oestrogen exposure and larger head size in newborn boys, using the ratio of ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that the gut microbiome does more than aid digestion. It may also influence how ...

What makes the human brain different from that of other primates has long been a question. A new study suggests that the answer may be in a surprising twist of evolutionary fate: one of the brain’s ...

This week, researchers reported the discovery of four Late Bronze Age stone megastructures likely used for trapping herds of wild animals. Physicists have proven that a central law of thermodynamics ...

A mechanism identified by a team from the Montreal Clinical Research Institute explains how the human brain reaches its ...

The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly ...

Scientists uncover how finger-length ratios in newborns reveal hormonal influences that may have shaped human brain evolution.
