Sentence examples for stage in the evolutionary from inspiring English sources

This scenario would have migratory behavior evolving at an early stage in the evolutionary history of bats.

Here, we use a transcriptomic approach to compare the dauer stage in the evolutionary model system Pristionchus pacificus with the dauer stage in C. elegans.

This has been interpreted by Hoare (1972) [ 4] as a relict form, representing an intermediary stage in the evolutionary pathway from the ancestral mechanical transmission to full adaption to the salivary glands of tsetse fly.

These results suggest that this gene evolved at an early stage in the evolutionary history of Proteobacteria, possibly predating the differentiation of δ- Proteobacteria (the most basal group in this clade).

This scenario would allow the three cells to incrementally develop trans-membrane transport systems that maintained appropriate lumen contents, thus obviating at any stage in the evolutionary process a discontinuous jump at which multiple cellular processes must simultaneously change for permanent internalization to succeed.

In P. patens, three sigma factors (PpSIG1, PpSIG2, and PpSIG5) are encoded in the nucleus (Hara et al. 2001; Hara, Sugita, et al. 2001; Ichikawa et al. 2004), suggesting that bryophytes (mosses, liverworts, and hornworts) are in an intermediate stage in the evolutionary expansion of the sigma factor family.

Early stages in the evolutionary pathway of cells presumably centred on RNA molecules, which not only present specific catalytic surfaces but also contain the potential for their own duplication through the formation of a complementary RNA molecule.

That dessert left me with faith in 5 Ninth, and in the possibility that the low points of the meal -- the too-tough meat on an appetizer of smoked pork ribs, a snapper entree without any snap -- were simply necessary stages in the evolutionary process, unsightly but unavoidable paces.

Family tree of Cnidaria and the origins of animals It is difficult to reconstruct the early stages in the evolutionary "family tree" of animals using only morphology (their shapes and structures), because the large differences between Porifera (sponges), Cnidaria plus Ctenophora (comb jellies), Placozoa and Bilateria (all the more complex animals) make comparisons difficult.

These three sets of consensus sequences represent distinct stages in the evolutionary history of the Family B protein from its original discovery in a pool of 4 trillion random sequences to its optimization for improved binding and subsequent optimization for improved folding.

Given three stages in the evolutionary history of an inversion (origin, establishment and maintenance), we consider RCIs to be early in the process of establishment: present in several copies in the population and potentially subject to selection and drift [ 9].
