DESCRIPTION:Speaker: Simon Martin\nhosted by Barton group\nAbstract: Recent
  population genomic studies provide countless examples of local adaptation
  associated with apparent chromosomal rearrangements (usually interpreted 
 as inversions). This may be unsurprising given the neat theoretical predic
 tion that inversions can be favoured if they maintain combinations of loca
 lly adapted alleles. But in order to truly understand the evolutionary mec
 hanisms that lead to the maintenance of rearrangement differences between 
 populations\, we need to dissect their history and genetics. In this semin
 ar I will describe our recent case studies in the butterfly Danaus chrysip
 pus\, in which several rearrangements differentiate distinct colour morphs
 . Ill show how scratching beneath the surface of this apparently simple sy
 stem reveals surprising complexity\, fueled by compounding rearrangements 
 and ongoing recombination. Our findings suggest that rearrangement evoluti
 on is dynamic\, and involves a broader range of both mechanisms and select
 ion pressures than initially hypothesised.
