Detailed explanation-1: -Definition. Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period.

Detailed explanation-2: -Divergent evolution is the process whereby groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species. Divergent evolution may occur as a response to changes in abiotic factors, such as a change in environmental conditions, or when a new niche becomes available.

Detailed explanation-3: -What Is Divergent Evolution? Divergent evolution occurs when a population of animals or plants is split into two groups by a geographic barrier (for instance, a body of water or a migration to a new area), causing each group to develop different traits under their respective selective pressures and natural selection.

Detailed explanation-4: -Common descent is an effect of speciation, in which multiple species derive from a single ancestral population. The more recent the ancestral population two species have in common, the more closely are they related.

Detailed explanation-5: -Convergent evolution refers to the evolution in different lineages of structures that are similar or ‘analogous’, but that cannot be attributed to the existence of a common ancestor; in other words, the fact that the structures are analogous does not reflect homology.
