Inter and intra island introgression in a wolf spider radiation from the Galápagos, and its implications for parallel evolution.

Abstract excerpt

Parallel radiations within island systems are often assumed to follow a simple scenario in which single colonization events are followed by in situ adaptive divergence. However, subsequent gene exchange after the initial colonization and during the divergence process might have important evolutionary impacts on species radiations. Gene exchange among ecologically similar species from different islands may lead to...
