DESCRIPTION:Speaker: Samuel Yeaman\nhosted by Nick Barton\nAbstract: Genome
 -Wide Association Studies have revealed that hundreds or thousands of loci
  commonly drive standing variation in adaptive traits\, which implies extr
 eme evolutionary potential with many different genotypic ways to evolve a 
 given phenotype. But in nature\, we often find the same gene contributing 
 to adaptation in distantly related species\, implying that adaptation tend
 s to work with a much smaller set of truly useful genotypes. What is the r
 eason for this discrepancy\, and what does it tell us about the flexibilit
 y of the evolutionary process? This presentation will explore this questio
 n and discuss projects in my lab studying: 1) the genomic basis of local a
 daptation to climate in a range of plants\, 2) theoretical predictions abo
 ut how genetics affects the repeatability of adaptation\, 3) a comparative
  genomic test of whether local adaptation favours the evolution of genomic
  rearrangements (in stickleback). Taken together\, this research shows tha
 t we know slightly more than nothing about the basis of adaptation\, but h
 ave an abundance of tools that may help us rectify this.
