Recombination Rate and Recurrent Linked Selection Shape Correlated Genomic Landscapes Across a Continuum of Divergence in Swallows.

ABSTRACT: Disentangling the drivers of genomic divergence during speciation is essential to our broader understanding of the generation of biological diversity. Genetic changes accumulate at variable rates across the genome as populations diverge, leading to heterogenous landscapes of genetic differentiation. The 'islands of differentiation' that characterise these landscapes harbour genetic signatures of the evolutionary processes that led to their formation, providing insight into the roles of these processes in adaptation and speciation. Here, we study swallows in the genus Hirundo to investigate genomic landscapes of differentiation between species spanning a continuum of evolutionary divergence. Genomic differentiation spans a wide range of values (F_ST = 0.01-0.8) between species, wi
