Sentence examples for because a higher speciation from inspiring English sources

The other is that the relationship between mutation rates and speciation is the other way round, because a higher speciation rate causes natural selection to preserve more of the mutations that arise, even though the mutation rate itself has not changed.The researchers eliminated the first possibility by selecting particularly common species for their study.

Do lineages without fitness trade-offs have different diversification rates than those with trade-offs, e.g. because those without trade-offs have reduced extinction, or because those with trade-offs have higher speciation rates?

We estimated a higher mean speciation rate (0.469, 90 % HPD 0.416-0.536) then the previous estimate for Murinae (speciation - extinction = 0.42, confidence interval = 0.37-0.48, [ 63]).

Further, we also found a similar pattern for Asian mammals with the tropical biomes showing higher speciation and non-tropical biomes showing lower speciation rates.

On the other hand, rapid gene rearrangements could impair the usage of gene order as phylogenetic character at high taxonomic level (because of a higher probability of gene order convergence in separate lineages) but will promote its usage to investigate speciation events [ 34].

Host species are considered as islands for parasites, and in view of the parasite life cycle we can expect parasite speciation to occur at a higher rate than host speciation.

Clearly, a more accurate phylogenetic framework is needed to interpret in detail the exceptionally high speciation rates reported here.

This is due to the fact that diversification within species is driven by mutation at a rate higher than speciation within lineages.

The apparent lack of speciation events within this taxon could be the result of a lower speciation rate, a higher migratory potential, or a relatively recent expansion of this species into the western IRSs of Madagascar.

At the beginning of the Pleistocene, elephantids experienced a high rate of speciation.

Thick films have a higher sensitivity for diagnosis while thin films allow more accurate speciation and quantification of parasitaemia.
