To the average life-science researcher, a mouse’s genetic background may be an afterthought, if even a thought, at all. A researcher’s top priorities may be to understand disease, to publish, and to ...

While evolution involves changes in organisms that we can observe, they undergo evolution at a deeper level, too. That is, changes affect the "letters" (four different types of chemical units) in the ...

For over a century, scientists imagined Neanderthals disappearing in catastrophe—felled by climate collapse, disease, ...

Africa is the birthplace of modern humans and the continent with the highest level of genetic diversity. While ancient DNA studies are revealing some aspects of the genetic structure of Africa before ...

In a recent study posted to the bioRxiv* preprint server, researchers developed and validated an approach for the joint inference of measurement noise and genetic drift by analyzing time-series data ...

Neanderthals may not have truly gone extinct, according to a new mathematical model that suggests they underwent genetic ...

People often talk about random genetic drift. Like sexual selection it is the deus ex machina of choice when you are shit out of luck in regards to hypotheses. And yet though it looms large in our ...
