Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which species ...

At this time of year, firemoths (Schinia masoni) can be seen on blanketflower (Gaillardia aristata), a colorful native wildflower. Evolution is the change of genetic forms in a population. We are ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. To suggest otherwise can provoke ...

Diseases have the potential to shape human evolution, leaving an indelible mark on the genetic code of generations to come. And that’s exactly what happened in South America, finds a study published ...

A surprising study on the behavior of unrelated lizards in very different parts of the world has demonstrated how evolution can lead to different species learning the same skills. The study documents ...

For well over a century, Darwin’s theory of natural selection has served as biology’s grand unifying framework, explaining how species adapt and evolve through the differential replication of randomly ...

Most of us know that as living things evolve, they take on traits that help them thrive in their home environments. But how are certain traits "chosen" for future generations, and how are others cast ...
