Sentence examples for by convergent evolution or from inspiring English sources

Did they arise by convergent evolution or were they transferred from species to species by lateral gene transfer?

Motifs shared among nonhomologous genes may have arisen independently by convergent evolution or by domain shuffling, and suggest a biochemical feature of general importance.

This grouping could be explained either by convergent evolution, or by the fact that all eight CD94L genes derive from a common ancestor.

Sand flies express related salivary proteins that might have been acquired by convergent evolution or share a distant common ancestor that can no longer be recognized with the available sequences.

There is some debate over whether bat echolocation is (1) a derived characteristic not present in the common ancestor that has subsequently evolved in multiple echolocating lineages by convergent evolution, or (2) was present in the ancestral species then selectively lost (Teeling 2009).

Species living in similar ecological environment can be shaped by convergent evolution to form physiological or morphological similarities (Stern 2013).

A consequence of the fact that species living in similar ecological environments can be shaped by convergent evolution to form physiological or morphological similarities [ 72].

For these virulence factors, it is not clear whether the pathogens picked up their actin nucleators by horizontal gene transfer or by convergent evolution, but in either case it is still striking that bacteria are easily able to nucleate eukaryotic actin filaments but do not seem to have any regulated protein nucleators for their own cytoskeletal filaments.

Structural similarity is either inherited from a common ancestor or arises by convergent evolution as the result of similar selective constraints.

While some superficially analogous processes may have arisen independently by convergent evolution (e.g. secretion of substrate- or tissue-macerating enzymes by both animal and plant cells), at the heart of cell invasion is an evolutionarily conserved machinery of cellular polarization and oriented cell mobilization, involving the actin cytoskeleton and the secretory pathway.

In these cases their true affinities may have been obscured by convergent evolution and morphological adaptations to new habitats or food sources, and genera like Myrmeciza antbirds and the Myrmotherula antwrens obviously need taxonomic revisions.
