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 is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
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 ...
The theory of evolution explains these homologous structures: all four animals shared a common ancestor, and each has undergone change over many generations. These changes in structure have produced forelimbs adapted for different tasks. [49] The bird and the bat wing are examples of convergent evolution.
Contrast divergent evolution. copulatory behavioral isolation coupling court jester hypothesis cospeciation A type of speciation in which more than two species speciate concurrently due to their ecological associations (e.g. host-parasite interactions). [15] crossbreeding. Also crossing and outbreeding.
We took the neurotypical vs. neurodivergent question to an expert and found out their definition, the differences between the two and, perhaps most importantly, why you should care. Read on for ...
Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by Lancelot Alexander Borradaile, who described it as "the many attempts of Nature to evolve a crab". [2]
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 ...
