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 ...

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

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 ...

A study quantifies for the first time the speed at which ape species have evolved, showing that the 'sapiens' skull and face evolved twice as fast as other species due to cognitive advantages and ...

The microorganisms in our gastrointestinal tract–the gut microbiome can exert a profound influence on the human body, and scientists are learning more about exactly how certain microbes can impact us.

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.

Autism spectrum disorder (ASD) may be the result of millions of years of evolution. Rapid neuronal evolution in humans is likely ASD’s genetic cause, new research suggests. Though autism can cause ...

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 ...
