Phenotype vs. Genotype in Crows

Science article.
Two lessons:
Small genetic differences can result in maintenance of speciation, putting lie to the assertion that “there is no such thing as race because genetic differences are too small.”
On the other hand, phenotypic differences can exist even in the face of widespread hybridization, demonstrating uncoupling of phenotype and ancestry, given that the phenotypic differences can result from selection on a relatively small number of alleles. Thus, the best way to gauge ultimate interests is to evaluate genotypes, not phenotypes.
