Detailed explanation-1: -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: -Homologous features Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.

Detailed explanation-3: -Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.

Detailed explanation-4: -Divergent evolution: Divergent evolution occurs when two organisms with a common ancestor end up as different species. For instance, bats and mice share a recent common ancestor, but divergent evolution has turned them into two entirely different species.

Detailed explanation-5: -New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups.
