Revealing the natural history of yeast
The following is a guest post by Matthew Vandermeulen, PhD, at the University at Buffalo. Matthew studies the regulation of responses to environmental variation; he is on Twitter as @mvandermeulen. Saccharomyces cerevisiae, baker’s and brewer’s yeast, may be one organism that could contend with dogs … Continue reading

Oh my ploidy … diploids evolve more slowly than haploids?
It’s been an embarrassingly long time since I last sat at my keyboard in a TME capacity (#NewPI chat doesn’t really count)! One year ago today, to be exact (writing this on 28 March, for publication on 29 March). Thus, … Continue reading

The why's of sex
Sex isn’t quite what it seems – while superficially wasteful in an evolutionary sense (why inherit on only one half of your genes, when you can inherit all of them asexually, or why waste resources in mating when you don’t … Continue reading
And who made your beer?
In the spirit of it being almost Friday, and while we’re on the topic of your favorite beverages – perhaps wine puts you to sleep, couldn’t care less where it came from, but prefer the bitterness of lager beers at your … Continue reading
Spontaneous mutations—friend or foe?
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

It is quite clear that humans play a major role in altering ecosystems today. Historic migration of human populations has been shown to have many interesting associated evolutionary consequences1,2. Worldwide travel makes it difficult to stop anything from going anywhere, … Continue reading

Where's the heritability? Right where you'd expect—if you look close enough
Biologists have at our disposal two major ways to assess how much genetics contributes to variation in the most interesting traits, or phenotypes, of our favorite study organisms—that is, the heritability of those phenotypes. There’s what you might call the … Continue reading
