Adaptation, speciation and hybrid zones

Nature. 1989 Oct 12;341(6242):497-503. doi: 10.1038/341497a0.


Many species are divided into a mosaic of genetically distinct populations, separated by narrow zones of hybridization. Studies of hybrid zones allow us to quantify the genetic differences responsible for speciation, to measure the diffusion of genes between diverging taxa, and to understand the spread of alternative adaptations.
