Sentence examples for constraints divergence from inspiring English sources

b Credibility interval (minimum and maximum averages of the analyses under the five ingroup root constraints) Divergence times within eubacteria (Fig. 3, Table 1, nodes A-K) show a pattern seen previously [ 30] whereby most major groups diverge from one another (nodes B-I excluding node D) in a relatively limited time interval, approximately between 2.5 3.2 Ga.

We set constraints on divergence times of i) the Drosophila and Sophophora subgenera, ii) the melanogaster and obscura groups and iii) the divergence of the species belonging to the melanogaster subgroup.

Thus, each CatSper group appears to have experienced altered evolutionary constraints after divergence from a putative ancestral duplication.

This method applies a relaxed molecular clock that does not require the assumption of constant evolutionary rates among genes and lineages, and allows the use of prior constraints on divergence times.

This stage is generally extremely conserved [ 31] suggesting that strong evolutionary constraints prevent divergence.

Similar time constraints for divergence times as used by Okajima and Kumazawa [ 18] were employed.

Based on the taxa sampled and three fossil constraints, earliest divergence within mosquitoes - between the lineages leading to Culicinae and Anophelinae - dates to ~226 Ma.

For adjustment of the deeper branches, we furthermore applied secondary age constraints, with divergence time estimates between mantellid genera based on the confidence intervals calculated in a previous study [ 69] (Additional file 1, Table S4).

We therefore conclude that being a part of the protein complex imposes certain constraints on divergence, and the process of orphaning coincides with an increased rate of sequence evolution.

Here, we have shown that the conservation of an amino acid's physico-chemical character exerts less and less constraint as divergence proceeds.

Also, the maximum constraint for divergence of gasterosteiform and tetraodontiform lineages is provided by the earliest euteleost record, e.g. Tischlingerichthys viohli.
