Posted on 16 September, 2019 by Katharine Coykendall

A month or so ago, I had opportunity to screen the documentary, “Artifishal” (admittedly, a pretty clever title), in a room full of fish biologists, geneticists, and hatchery managers.  The premise of the film is that both hatcheries and open … Continue reading →

Population genomics finds veritas in the demographic history of vino

Posted on 17 October, 2017 by Jeremy Yoder

One of the more, hah, fruitful applications of genomic data has been in crop and livestock improvement. Biologists know that domesticating plants and animals for human use has involved powerful artificial selection — usually inadvertent at first, then intensive and … Continue reading →

Non-model organisms are so hot right now

Posted on 4 August, 2017 by Kelle Freel

What makes a model organism? Well, as the name suggests, they are widely studied and have been adapted to a vast array of common genetic techniques. A few of the most often utilized organisms, which you are most likely already … Continue reading →

The not so singular process of hybridization

Posted on 27 May, 2016 by Stacy Krueger-Hadfield

What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading →

Genomics of domestication in chicken and cattle

Posted on 29 October, 2015 by Arun Sethuraman

Two recent studies attempt to understand the process of adaptive evolution in domestication and artificial selection by characterizing (a) sweeps, and their association with phenotypes in extant hybrid lines (Sheng et al. 2015), and (b) phylogenomic position of an extinct … Continue reading →

Small mammalian genomics of adaptation

Posted on 10 September, 2015 by Arun Sethuraman

While large mammals have had their day on our blog, two recent studies on small mammals reveal the genetics of size evolution in island mice, and differential introgression of mitochondrial and nuclear genomes in chipmunks – steps towards understanding the … Continue reading →
