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 ...

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 ...

The longer the thumb, the bigger the brain, evolution study suggests By Pranjal Malewar September 07, 2025 The research found the bigger a primate's brain the longer its thumbs were, affirming a ...

What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...

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, ...

Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found. The study ...

A part of the brain called the pallium is responsible for many complex functions. In mammals, the pallium is thought to be where the neocortex forms, and gives rise to the cerebral cortex and ...

Flight is a rare skill in the animal world. Among vertebrates, it evolved only three times: in bats, birds, and the long-extinct pterosaurs. Pterosaurs were the pioneers, taking to the skies more than ...

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 largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed. The largest animals do not have proportionally bigger brains -- with humans ...

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 ...
