Sentence examples for decrease in the evolutionary from inspiring English sources

Proteins in such complexes are usually expressed at very similar rates and should, by analogy to fusions, demonstrate a similar decrease in the evolutionary rate difference.

This suggests that the 42% lower overall evolutionary rate of TM regions relative to EM regions (fig. 2) is due to a combination of two effects: 1) a general enrichment for buried, slowly evolving residues in TM regions (fig. 3 A) and 2) a systematic decrease in the evolutionary rates of all TM residues, independent of degree of burial (fig. 4).

Broadly speaking, we conceptualize diversifying selection on continuous characters as causing an increase and purifying selection on such characters a decrease in the rate of evolutionary change.

When this is done for study [ 10], the bias to count more interactions for abundant proteins is slightly reduced and there is a concomitant decrease in the association between evolutionary rate and the number of interactions (Table 1).

In such a case, the two variances decrease throughout the evolutionary time course, indicating increase in robustness.

Thus, in addition to their difference in RSA distributions, EM and TM regions differ markedly in their amino acid composition, and this could also potentially contribute to the decrease in overall evolutionary rate in TM regions (Graur 1985).

The decrease in evolutionary rate possibly reflects a plateau in the fixation of the novel function.

We discuss potential reasons for the general decrease in evolutionary rate observed over time, although the difference in evolutionary rates is not significant and the datasets are not independent so this result should be interpreted with caution.

Three main trends can be observed: first, a sustained decrease in evolutionary rate for the A3 subfamilies in the last 100 Mya; second, duplication events have occurred in the A3Z1 and A3Z2 subfamilies, but not in the A3Z3; third, duplication events accumulate in the last 50 Mya.

These results are similar to a previous study, where predation by the protozoan Tetrahymena thermophila led to an evolutionary decrease in the pathogenicity of S. marcescens bacterium [40].

A decrease of the rλ indicates differences in the evolutionary rates between the original and the duplicate copy, and a measure of such divergence is assigned as θ = 1−rλ, where θ is a coefficient of functional divergence [15].
