Human and chimpanzee genomes are more than 98% identical, and the genes themselves barely differ. The changes that make us ...

Some scientists say humans may be entering a new phase of evolution, one in which culture is becoming more powerful than genes in shaping our survival and future. At the heart of that idea is a ...

The pelvis is often called the keystone of upright locomotion. More than any other part of our lower body, it has been radically altered over millions of years to allow us to accomplish our bizarre ...

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 ...

Natural selection has long been considered the driving force behind human evolution. But a landmark study of 87 fossil skulls spanning the past two million years suggests the story is far more complex ...

(Reuters) -Researchers have unearthed tooth fossils in Ethiopia dating to about 2.65 million years ago of a previously unknown species in the human evolutionary lineage, one that lived in the same ...

Human newborns arrive remarkably underdeveloped. The reason lies in a deep evolutionary trade-off between big brains, bipedalism and the limits of motherhood. Why is it that, compared to most other ...

A new study concludes that the speed at which the human brain evolved may help explain why our species experiences autism. According to the authors, certain genes associated with autism are ...
