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 ...

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 ...

A strange tiny species of crustacean has challenged the way we think about natural selection and evolution. This microscopic animal, known as a water flea or Daphnia pulex, generates genetic variation ...

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 ...

Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows. Natural selection can reverse evolution that occurs through sexual ...

Scientists have identified a new member on the genetic family tree of an endangered pupfish native to south-central New Mexico. "We went into this thinking that there was one species of conservation ...

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 ...
