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 ...

Researchers report using computer simulations to demonstrate an important aspect of evolutionary theory: that complex structures, like the eyeball, can arise through evolution. So-called digital ...

Abrupt shifts in the evolution of animals -- short periods of time when an organism rapidly changes size or form -- have long been a challenge for theorists including Darwin. Now a newly published ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team showed that a group of highly divergent mammals known as Afrotheria and distantly ...

Human evolution has often been depicted as a process of adaptation, where natural selection and genetic changes drive species toward better-suited traits for survival in their environments. But this ...

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 ...
