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 ...

Chaotic genetic patchiness denotes unexpected patterns of genetic differentiation that are observed at a fine scale and are not stable in time. These patterns have been described in marine species ...

I know I've posted on this topic before, but I thought I'd revisit it again. You do know that sometimes population bottlenecks can actually result in more variation being freed up for selection? This ...

A whimsical attempt to establish a herd of mouflon for sport hunting on a remote island in the Indian Ocean 50 years ago has inadvertently created a laboratory for genetic researchers and led to a ...

Studies of island bird populations have taught us a lot about evolution, but it's hard to catch birds in the act of naturally colonizing new islands. Instead, a new study from The Auk: Ornithological ...

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 ...

“The survival and preferential multiplication of types better adapted to the environment (natural selection) is the basis of evolution. Into this process, however, enters another kind of variation ...

WEST LAFAYETTE, Ind. — 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 ...
