One of the defining features of human evolution is the steady expansion of our brains. New findings suggest this growth may be partly linked to higher levels of estrogen before birth. Surprisingly, a ...

The human brain is one of the most complex structures in nature, but the brain's origins stretch back hundreds of millions of years. A new study using AI deep-learning models has revealed more about ...

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 ...

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 ...

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 ...

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

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 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, ...

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 ...

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 ...

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 ...
