Morphs, dispersal behavior, genetic similarity, and the evolution of cooperation.

Science (New York, N.Y.) - 20 Jun 2003

Sinervo Barry, Clobert Jean

Abstract excerpt

Genetic similarity owing to kin relationship is often invoked to explain the evolution of social cooperation. In this study, male color morphs of side-blotched lizards settle nonrandomly with respect to genetic similarity. Blue morphs tend to settle in close proximity to other blue morphs with high genetic similarity. Blue neighbors have three times the average fitness of blue males lacking such neighbors....
