Some people might think that human bones have become stronger through evolution. Walking on two legs, supporting a large ...

Human and chimpanzee genomes are more than 98% identical, and the genes themselves barely differ. The changes that make us human are thought to hide instead in the DNA that controls when and where ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...

The human body is often described as a marvel of “perfect design”: elegant, efficient and finely tuned for its purpose. Yet, when we look closer, a rather different picture emerges. Far from being a ...

A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains. Boys with finger-length patterns linked to higher estrogen exposure before birth ...

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 ...

South Africa has one of the world’s richest fossil records of hominins (humans and their fossil ancestors). But many misconceptions still exist regarding human evolution, and school textbooks contain ...
