Abstract:
Here we accelerate the understanding of the genetic underpinnings of convergent evolution by conducting genome scans for divergent genomic regions between two surface fish populations and three cave fish populations, at least two of which are independently derived. We examined the data for 1) areas of exceptionally high genetic divergence between cave and surface fish across their genomes, and 2) regions that are different between the two independent evolutionary origins of cave fish. Since these divergent genomic regions are often the smoking guns of adaptation, we catalogued which genes are embedded in them and estimated the role of natural selection in creating these divergent regions.
