Sentence examples for precise divergence from inspiring English sources

Therefore, detailed phylogenetic analysis based on full-length mitochondrial genomic sequences using additional Selachii species that are thought to be diverged on evolutionary important positions, will be necessary for estimation of the precise divergence times in future.

Although amino acid sequence data sets for cytochrome c do have phylogenetic implications over long time periods, its relatively short amino acid sequence cannot be expected to provide precise divergence times and phylogenetic relationships in all cases.

Due to the lack of fossil calibration and the asymmetric evolutionary rates between subfamilies, it is difficult to estimate the precise divergence time of each node in such a long evolutionary time.

However, it has subsequently been demonstrated that the dating method used in Sorhannus (PATHd8 [73], [73]) is statistically biased, generating overly young and precise divergence time estimates [74], and has produced statistically significant dissonant inferences for empirical data when compared to more vetted analytical methods [47], [75].

They fail to integrate different sources of uncertainties, which make accurate and precise divergence time estimates impossible with current data and methods.

Evolutionary analysis of these two Primula species not only revealed a more precise divergence time, but also provided some novel insights into how differential adaptations occurred in extreme habitats.

In our analyses, we found considerable differences among genes in their ability to provide congruent and precise divergence-time estimates.

Not surprisingly, exponential priors (lending more credence to a strict reading of the fossil record) generated generally younger and more precise inferred divergence times than the considerably broader lognormal priors (which model an expected lag between speciation and diagnosable fossil deposition).

Instead, we found a conserved internal promoter at the precise position where divergence in disease severity occurs, with the resulting protein product partially rescuing N-terminal truncations.

However, because for this study we were concerned with obtaining precise estimates of divergence time, and as our haplotype networks and knowledge of the natural history of the Mexican jay suggested little or no current gene flow among sky islands, we present results from an isolation model where migration rate was set to zero (m1 = m2 = 0).

All three groups (owls, accipitrids [eagles], and falcons) do appear to be members of the "higher land birds," and though there may not yet be full "consilience" between mitochondrial and nuclear sequences for the precise order of divergences of the eagles, falcons, and the owls, there is good progress on their relationships.
