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 ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

Evolution is a complicated thing. Much of modern evolutionary biology seeks to reconcile the seeming randomness of the forces behind the process — how mutations occur, for example — with the ...

The movement of genetic material between organisms that aren’t directly related is a significant driver of evolution, especially among single-celled organisms like bacteria and archaea. A team led by ...

An updated evolutionary model shows that living systems evolve in a split-and-hit-the-gas dynamic, where new lineages appear in sudden bursts rather than during a long marathon of gradual changes.

From popular culture to the dark corners of the internet, there are many claims about “fundamental” differences between people on the basis of gender, racial or ethnic groups, sexuality, or other ...
