Historically, islands are places where the most dramatic morphological and genetic differentiations have occurred (Grant 1998, 2001). Geographic isolation between populations is expected to promote differentiation of both morphological and genetic characters, due to either drift or different selective regimes (Slatkin 1985, Bohonak 1999). This may reflect population divergence due to insufficient gene flow that would counteract the effects of drift and selection (Slatkin 1985, Hutchison and Templeton 1999, Coleman and Abbott 2003). Isolation leads to the formation of geographical races, which is considered one of the initial stages of speciation (Grant 2001). However, ...
