One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

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.

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 ...

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.

A paper in Molecular Biology and Evolution finds that the relatively high rate of autism-spectrum disorders in humans is likely due to how humans evolved in the past. The paper is titled "A general ...

In a new study, researchers discovered that the human brain has four pivotal periods when it goes through marked changes, sparking five "epochs" that last for years. The adolescent phase, for example, ...
