From cats to rats: two studies on domestication and tameness

Posted on 18 Nov, 2014 by Noah Snyder-Mackler

Anyone who has ever read Charles Darwin is acutely aware of his fascination with domestication – particularly how he fancied fancy pigeons. Darwin drew on his domestication obsession while writing his book, The Variation of Animals and Plants under Domestication, … Continue reading →

The forest resounding at rare intervals with the note of … reproductive isolation

Posted on 14 Nov, 2014 by Stacy Krueger-Hadfield

Hybrid zones are often used as a window with which to gaze upon the evolutionary process (Barton and Hewitt 1989). With the advent of genomic tools, it is possible to detect the genomic signatures and the architecture underlying reproductive isolation. In … Continue reading →

WTF (What's The Function?)

Posted on 4 Nov, 2014 by Noah Snyder-Mackler

Jay Shendure’s editorial, “Life after genetics”, points out that we, as geneticists, should shift our focus from variant-finding (e.g., GWAS) to understanding the functional implications of disease-associated variants: “We are in a period of rich discovery in human genetics and genomics. The … Continue reading →

How many markers does it take to make a dataset "genomic"?

Posted on 9 Oct, 2014 by Jeremy Yoder

A new paper in Ecology Letters by Matthew Fitzpatrick and Stephen Keller proposes to use some a class of statistical methods developed for understanding the distribution of species in different environments to understand the distribution of genetic variants in different … Continue reading →

Spontaneous mutations—friend or foe?

Posted on 16 Jun, 2014 by Jeremy Yoder

The following is a cross-posting from the Stanford CEHG Blog by Ryo (Ryosuke) Kit, a graduate student in Hunter Fraser’s lab at Stanford University. Evolution has conflicting opinions about spontaneous mutations. Spontaneous mutations produce the genetic variation that drives evolution … Continue reading →

Scanning the genome for local adaptation

Posted on 23 Apr, 2014 by Jeremy Yoder

One of the most obvious and important applications of evolutionary genetics is in figuring out whether natural biological communities are going to be able to adapt to global climate change. The projected rate of climate change over then next century … Continue reading →

2014 NGS Field Guide: Resistance is Futile (mostly, at least for a while)

Posted on 4 Mar, 2014 by Jeremy Yoder

This year, to introduce the 2014 update to his Next Generation Sequencing Field Guide—perennially our most-accessed community resource—Travis Glenn has a bit more to say than just what goes in the tables. So here it is as a guest post! … Continue reading →

No reference genome? No problem! Demographic inference from genomic data in nonmodel insect populations

Posted on 19 Dec, 2013 by Jeremy Yoder

This guest article by Martin Sikora is cross-posted from the Computational, Evolutionary and Human Genomics blog at Stanford University. Reconstructing the demographic history of species and populations is one of the major goals of evolutionary genetics. Inferring the timing and … Continue reading →

Want to share your code?

Posted on 27 Aug, 2013 by kimgilbert

In this line of work, we have all encountered tasks that are tedious, time consuming, and repetitive.  (Or if not, maybe give it a bit more time.) When confronted with these situations, people tend to fall into one of two … Continue reading →

Phylogeny-aware comparisons of microbial communities – EdgePCA and Squash Clustering

Posted on 25 Mar, 2013 by hollybik

I’m jumping on the bandwagon with a blog post about this new PLoS ONE paper (taking the lead from the man in charge in my lab) because the algorithms are just so exciting: Matsen FA IV, Evans SN. (2013) Edge Principal … Continue reading →
