Sentence examples for this speciation from inspiring English sources

(For additional discussion of this speciation mechanism, see evolution: Geographic speciation).

This speciation occurs because different parasitic populations become adapted to living on different hosts and coping with the defenses of these hosts.

This speciation process, known as hybridization, may play a larger role in evolution than is currently believed, the researchers propose.

Paleontologists also have an important role to play in testing the hypothesis that the burst of speciation in the Holocene is an artifact of differential collection, differential preservation or both, and that some of this speciation occurred in preceeding epochs.

A reproduction of this speciation is presented in Figure 2, where in using the chemical equilibrium software Mineql+ [24] we show that adding citrate and oxalate, should complex most of the Al in the LMW human serum [20, 22, 25 27].

In consequence, the geographic localizations of O. rufipogon and O. sativa in Asia and of O. barthii and O. glaberrima in West Africa, together with a restricted gene flow could imply that this speciation process is the result of geographical isolation, in agreement with the current hypothesis of a common Asian origin and ancestral migrations to Africa [19], [20].

Although the precise conditions for this speciation-like phenomenon has not been completely elucidated, it seems that a bimodal distribution can evolve when the advantage of producing P and that of producing M – which result from diffusion being finite – are sufficiently and more or less equally strong (see the legend of Fig. 9 for the parameter conditions).

We discuss the ecological conditions and mechanisms that likely generated this ongoing speciation and the relevance of this new specialist taxon in the genus Cotesia for biological control.

These results confirm the mechanism of adaptation already proposed in this species and a minor role of phenotypic plasticity in this ecological speciation process.

In this sense, speciation (the production of new species) = reproduction (the production of new individuals).

Therefore, Equation 1 is only valid as long as this surface speciation is constant.
