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 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 ...

For most of human evolution, the story of the brain seemed to move in one direction. It got bigger. That long rise is still there in the fossil record. But a new analysis argues that the trend did not ...

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 ...

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.

How did humans get such big brains – the answer might lie in the gut. A recent study from Northwestern University in the US is the first to show that gut microbes from different animals can shape ...

What makes the human brain distinctive? A new study published in Cell identifies two genes linked to human brain features and provides a road map to discover many more. The research could lead to ...

The time has come to reconsider an outdated understanding of human evolution: it was ...

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 ...

The human brain's remarkably prolonged development is unique among mammals and is thought to contribute to our advanced learning abilities. Disruptions in this process may explain certain ...

Octopuses and squids carry the largest nervous systems of any invertebrate, and roughly two-thirds of an octopus’s neurons ...
