Sentence examples for adaptive speciation from inspiring English sources

Male orange colour is potentially a main target of both mate choice [27] and predation [19], therefore presenting a classic scenario for adaptive speciation.

Our study thus confirms that mechanisms of adaptive speciation are not necessarily mutually exclusive and uncovers the complex ecology-geography interactions that underlie the evolution of mating isolation in nature.

These results provide the first evidence for a novel mechanism of adaptive speciation and the first evidence of adaptive divergence at the MHC in closely related African cichlid fishes.

The accumulation of disparity with species diversity may drive further adaptive speciation as a positive feedback.

Accordingly, speciation models seemed to suggest that adaptive speciation is a rare and unlikely phenomenon.

Here, we discuss two main modelling approaches in adaptive speciation theory.

The second study suggests an important role for non-adaptive speciation, at least in the Bignonieae.

The commonest form of non-adaptive speciation (in the sense of the biological-species definition) in plants is probably polyploidy.

In contrast, non-adaptive speciation, even if rare, is of conceptual importance because it potentially decouples species-level selection (Stanley 1975) from microevolution (Gould 2002).

An apparent lack of morphological diversity could be attributable to non-adaptive speciation, but morphometric work would be required in order to quantify phenotypic diversity.

From the overview presented in the Introduction, it is clear that flowers may influence diversification in several ways, involving both adaptive (trait transitions, reduced extinction rates, adaptive/ecological speciation) and non-adaptive processes (e.g. non-adaptive speciation).
