Parallel evolution of site‐specific changes in divergent caribou lineages
Abstract The parallel evolution of phenotypes or traits within or between species provides important insight into the basic mechanisms of evolution. Genetic and genomic advances have allowed investigations into the genetic underpinnings of parallel evolution and the independent evolution of similar...

Abstract The parallel evolution of phenotypes or traits within or between species provides important insight into the basic mechanisms of evolution.
