Genomics of Adaptation Paper

Very cool paper looking at the genetics of ecological divergence during speciation http://go.nature.com/etsH7I

Many loci with small phenotypic effects act additively during niche divergence and hybrids are phenotypically mismatched to naturally occurring niches (i.e., morphologically, they end up in a fitness valley). An interesting paper giving the later finding some theoretical support was also recently published in Evolution (http://onlinelibrary.wiley.com/doi/10.1111/evo.12346/abstract).
