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 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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

Recent fossil and skull studies reveal a surprising trend: Despite a fourfold increase in brain size starting around 2 million years ago, which coincided with major advancements in tool use, social ...

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

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 ...
