Key Takeaway Key Takeaway: Migration may contribute to bursts of speciation in seasonal migrant lineages, as new species arise through population differentiation without spatial isolation.
Abstract
Although migration is a common behaviour, the effects of this annual two-way event on the speciation process are poorly understood, even though birds, which are commonly migratory b played a critical role in the development of speciation theory. Here I propose that new developments in the theory of sympatric speciation — a process whereby new species can arise through population differentiation without spatial isolation — may help to explain the bursts of speciation observed in some seasonal migrant lineages.
