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 ...

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 ...

By analyzing the genetic material of thousands of ancient humans, researchers have mapped how natural selection influenced hundreds of physical and behavioral traits across West Eurasia over the past ...

Erangi Heenkenda, co-lead author of the PNAS paper who received her PhD in forestry and natural resources from Purdue this month, prepares to take a sample from a frozen pupfish that will be used for ...
