Predictable adaptive trajectories of sexual coloration in the wild: Evidence from replicate experimental guppy populations.

Abstract excerpt

The question of whether populations evolve predictably and consistently under similar selective regimes is fundamental to understanding how adaptation proceeds in the wild. We address this question with a replicated evolution experiment focused upon male sexual coloration in guppies (Poecilia reticulata). Fish were transplanted from a single high predation population in the Guanapo River to four replicate,...
