My next post on Gillespie's chapter in Evolutionary Genetics: Concepts & Case Studies is going to cover "genetic draft." I don't know when I'll get to it, so I'll point to Robert Skipper's post on the topic from six months ago. Yes, selection is proximately stochastic. Like this.

Over the past month or so I've been blogging chapter 5 of Evolutionary Genetics: Concepts & Case Studies. This chapter covers "stochastics processes," basically the random elements in the flux of gene frequencies in biological populations. Now, I'm a selection man for real, but to understand…
I have spoken of the probability of extinction and the rate of substitution once past extinction, but now to something more prosaic, genetic drift. My post is based on John Gillespie's treatment in Evolutionary Genetics: Concepts & Case Studies. Like R.A. Fisher he does not think much of…
The idea of stochastic training wheels sounds a bit scary, but I am alluding to the series of posts on stochastic dynamics adapted from chapter 5 of Evolutionary Genetics: Concepts & Case Studies by John Gillespie. Using Gillespie's terminology the posts were:
Boundary Process

Bora made two quick references to "group selection" today. I don't have much time...and shouldn't be blogging, but I want to make a few quick points before this topic goes down the memory hole (I know, unnecessary caveat, but I am driven by personal guilt in expressing it, not public shame). For…
