Sentence examples for stage of divergence from inspiring English sources

This lack of sharing suggests that the two lineages are at an intermediate stage of divergence along the continuum from complete panmixia to paraphyly and ultimately to reciprocal monophyly [ 106, 107].

Combined information about multiple, independently evolving traits, such as morphology and structural and behavioural differences in calling song, provides greater resolution of the overall differences between these allopatric populations, and allows us to assess their stage of divergence.

Because we want to predict how reproductive isolation (RI) develops along the whole continuum of species formation, our operational units need to be at any diagnosable stage of divergence along the gradient from genetically distinct populations, ecomorphological groups (subspecies), and reproductively isolated taxa.

Polytypic species and complexes of closely related species provide unusual opportunities to study the linkage between micro and macro evolutionary processes directly in nature because they are composed of taxa that persist at various stages of divergence, from genetically differentiated populations to ecologically divergent taxa.

"[E]volutionary history is best verified through concordance among genetic markers from across the genome that are inherited maternally, paternally and bi-parentally and that evolve at different rates to capture different stages of divergence.

Our results reinforce the importance of examining interactions between ecological and geographical factors in the early stages of divergence and speciation [1], [2], [40].

Both hybrid sexes from these crosses were completely fertile, suggesting that Haldane's rule is not operating in toads at the earliest stages of divergence [27].

We stress that arguments for the existence of stages of divergence do not rely on strict gradualism; shifts between stages could arise after long periods of little or no change, such that divergence is not always ongoing.

For species in intermediate stages of divergence it is often difficult to differentiate between the alternative possibilities of contemporary gene flow and recent isolation with retention of ancestral polymorphism due to incomplete lineage sorting.

Despite this reconciliation, evolutionary biologists still have great difficulty in recognizing species in the early stages of divergence due to the limited time for differences to evolve that satisfy most delimitation criteria [5].

Both of these circumstances may arise during the early stages of divergence, when a population is splitting into incipient species.
