Does hybridisation influence speciation?
As Butlin et al. (2012) emphasise, hybridisation occurs almost inevitably during speciation. Moreover, studying patterns of introgression across the genome, and the spatial structure of hybrid zones, can tell us much about the genetics of divergence and reproductive isolation. Nevertheless, hybridisation may well have a negligible effect on the actual process of speciation. On the one hand, uni...
متن کاملHow does climate influence speciation?
Variation in climatic conditions over space and time is thought to be an important driver of speciation. However, the role of climate has not been explored in the theoretical literature on speciation, and the theory underlying empirical studies of climate and speciation has come largely from informal, verbal models. In this study, we develop a quantitative model to test a relatively new but the...
متن کاملHybridization and speciation.
Hybridization has many and varied impacts on the process of speciation. Hybridization may slow or reverse differentiation by allowing gene flow and recombination. It may accelerate speciation via adaptive introgression or cause near-instantaneous speciation by allopolyploidization. It may have multiple effects at different stages and in different spatial contexts within a single speciation even...
متن کاملHybridization and speciation in centrarchids
Open any field guide and you will find a list of species, with brief descriptions of how to distinguish each species from other closely related species. Such field guides convey an impression of stable, cleanly delineated groups. This can lead to significant confusion when our orderly Linnean categories run into the sometimes messy reality of biology. For example, consider the recent controvers...
