The right-hand species may undergo divergent, parallel, or convergent evolution at this amino acid position relative to the first species. When two species are similar in a particular character, evolution is defined as parallel if the ancestors were also similar, and convergent if they were not.
Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation ) and experience different ...
Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome , as similar environments will select for similar traits in any species occupying the same ...
However, the criteria for defining convergent as opposed to parallel evolution are unclear in practice, so that arbitrary diagnosis is common. When two species share a trait, evolution is defined as parallel if the ancestors are known to have shared that similarity; if not, it is defined as convergent.
Convergent evolution is the process in which related or distantly related organisms evolve similar characteristics independently. This type of evolution creates analogous structures which have a similar function, structure, or form between the two species. For example, sharks and dolphins look alike but they are not related.
divergent evolution. Also divergence. The process by which any phenotypic or genotypic distinction emerges between two different populations or evolutionary lineages. Divergence may occur by any of a variety of mechanisms but is often especially noticeable after the two lineages have been reproductively isolated for many generations. [7 ...
After the final Divergent film’s 2016 debut, many of the franchise’s stars have gone on — or continued — to have very successful acting careers. Based on Veronica Roth’s book series of ...
