Evolution and stability of ring species.

Proceedings of the National Academy of Sciences of the United States of America - 26 Mar 2013

Martins Ayana B, de Aguiar Marcus A M, Bar-Yam Yaneer

Abstract excerpt

Neutral models, in which genetic change arises through random variation without fitness differences, have proven remarkably successful in describing observed patterns of biodiversity, despite the manifest role of selection in evolution. Here we investigate the effect of barriers on biodiversity by simulating the expansion of a population around a barrier to form a ring species, in which the two ends of the...
