Digest: Exploring genomic islands of differentiation on the Z chromosome of hummingbirds.

Published in: Evolution; international journal of organic evolution (2020)

What evolutionary processes shaped the genomic landscape of differentiation in Selasphorus hummingbirds? Battey shows that the islands of differentiation on the Z chromosome are most likely the outcome of linked selection. Furthermore, these islands might contain barrier loci that contribute to reproductive isolation between these hybridizing hummingbirds.
