Eighty-six billion interconnected neurons comprise the human brain, the product of billions of years of evolution. However, the mechanisms supporting the evolution of this remarkable structure over ...

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 ...

Research on the lamprey brain has enabled scientists to push the birth of the cortex back in time by some 300 million years to over 500 million years ago, providing new insights into brain evolution.

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 ...

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 ...

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 ...

In the mice with large-brain primate microbes, the researchers found increased expression of genes associated with energy production and synaptic plasticity, the physical process of learning in the ...

Evolution, Vol. 70, No. 7 (JULY 2016), pp. 1559-1568 (10 pages) Brain size is strongly associated with body size in all vertebrates. This relationship has been hypothesized to be an important ...

Human placentas produce exceptionally high hormone levels that may have driven our brain evolution, not male competition as traditionally thought These pregnancy hormones directly influence fetal ...

A molecular atlas of an Australian dragon's brain sheds new light on over 300 million years of brain evolution. Neuroscientists at the Max Planck Institute for Brain Research in Frankfurt tackled this ...
