This week we will read a recent paper by Patrik Nosil and colleagues on the repeatability of the genetic changes driving the divergence of populations into new species. The paper is entitled "Stick Insect Genomes Reveal Natural Selection’s Role in Parallel Speciation" and was recently published in Science. The reported findings indicate that natural selection can drive parallel phenotypic evolution via parallel genetic changes.

 

Time and place: May 15, 2014 12:00 PM1:00 PM, Seminar room 3315

This week we will discuss what are the rate-limiting factors for the establishment of new species. In this regard, we will read a recent paper by Trevor Price and colleagues on the factors determining the rate of speciation in Himalayan song birds. The paper is entitled "Niche filling slows the diversification of Himalayan songbirds" and was recently published in Nature. The findings by Price et al. suggest that it is the rates at which new niches are created and occupied that limits diversification, not the rate at which new species form through reproductive isolation.
