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 ...

Longer thumbs mean bigger brains, scientists have found—revealing how human hands and minds evolved together. Researchers studied 94 different primate species, including fossils and living animals, to ...

A new study reveals how transposable elements (TEs) expanded gene regulation during brain evolution, shaping modern neural ...

Humans, who are classified among the five great apes, are closest genetically, i.e., DNA similarity, to chimpanzees (98.8%-99%) and bonobos (98.8%). [Blueringmedia ...

In a new study published in Science, a Belgian research team explores how genetic switches controlling gene activity define brain cell types across species. They trained deep learning models on human, ...

New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...
