Genomic differentiation across the speciation continuum in three hummingbird species pairs.

ABSTRACT:

Background

The study of speciation has expanded with the increasing availability and affordability of high-resolution genomic data. How the genome evolves throughout the process of divergence and which regions of the genome are responsible for causing and maintaining that divergence have been central questions in recent work. Here, we use three pairs of species from the recently diverged bee hummingbird clade to investigate differences in the genome at different stages of speciation, using divergence times as a proxy for the speciation continuum.

Results

Population measures of relative differentiation between hybridizing species reveal that different chromosome types diverge at different stages of speciation. Using F_ST as our relative measure of differentiation we
