Sentence examples for more adaptive evolution from inspiring English sources

This suggests that although both classes of sites experience frequent adaptive fixation, non-domain codons may experience more adaptive evolution than domain codons.

Our data are consistent with the hypothesis that immune system genes undergo more adaptive evolution than non-immune system genes, possibly as a result of host-parasite arms races.

Furthermore, Drosophila simulans does not appear to have undergone more adaptive evolution than D. melanogaster, even though it is thought to have a larger Ne (Andolfatto et al. 2011).

Consistent with the results obtained from humans [ 2], rodents [ 3], chickens [ 4] and fruit flies [ 5], our data support the hypothesis that on average immune system genes have experienced more adaptive evolution than non-immune system genes.

In support of the hypothesis, results from a multilocus extension of the McDonald-Kreitman (MK) test indicate that immune system genes as a class have experienced more adaptive evolution than non-immune system genes.

We found that, as a class, immune system genes show more adaptive evolution than non-immune system genes, supporting the hypothesis that host-parasite co-evolution is an important force in shaping genomes.

On the other hand, it also tends to experience more effective adaptive evolution and show a faster evolution rate, since its hemizygous state in male would more readily expose the male recessive beneficial mutations to positive selection ('fast-X' evolution) [ 15, 16].

Such neutral mutations therefore provide a standard for measuring the action of natural selection: regions changing more slowly than neutral ones are inferred to be experiencing purifying selection (e.g., selective constraint), those changing more rapidly, adaptive evolution.

According to the exon shuffling theory, it is believed that shuffled exons can create functional diversity in novel proteins making the species more adaptive during evolution [ 26].

Given the general observation that a substantial proportion of protein divergence is adaptive in Drosophila (Smith and Eyre-Walker 2002; Fay et al. 2002; Begun et al. 2007; Langley et al. 2012), one interpretation of increased dN/ dS ratio on the X is more adaptive protein evolution on the X chromosome.

The mean neutrality index in protein domains was significantly higher than non-domain regions (analysis of variance: p = 0.0030; both distributions were normally distributed after log2 transformation) indicating more frequent adaptive evolution in non-domain regions, which is consistent with the interpretation of the MK tests on pooled domain and non-domain codons.
