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

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 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 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 ...

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

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 ...

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.

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

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, ...

Scientists find clue to human brain evolution in finger length: Study ...
