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 ...

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 ...

Artificial intelligence allows tracing the evolution of genetic control elements in the developing mammalian cerebellum. An international research team led by biologists from Heidelberg University as ...

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 ...

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.

A groundbreaking international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The research reveals that our human ancestors were periodically ...

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 ...

This measure compares the length of the index finger to the ring finger, a relationship called the 2D:4D ratio. Scientists have shown that this ratio reflects the balance of estrogen and testosterone ...
