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 ...

Newborn finger proportions may reflect early hormone exposure and could be linked to differences in early brain growth.

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

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 ...

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

How did humans get such big brains – the answer might lie in the gut. A recent study from Northwestern University in the US is the first to show that gut microbes from different animals can shape ...

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to thrive ...

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

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

Researchers have used a new human reference genome, which includes many duplicated and repeat sequences left out of the original human genome draft, to identify genes that make the human brain ...
