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 ...

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 ...

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 human hands is one of the most important – and overlooked – stories of our origin. Now, new fossil evidence ...

A new study from the School of Neurobiology, Biochemistry, and Biophysics reveals a surprising insight into the operation of the ancestral brain: the visual cortex of turtles is capable of detecting ...

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.

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

The evidence doesn't take us all the way back to the origins of genus Homo in Africa, but it does demonstrate that as brain size increased, there was very likely an expansion of the hominid diet that ...

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 ...
