Question

How do homologous organs represent divergent evolution? Explain with the help of a suitable example. [3]

Answer 1

Divergent evolution is the process whereby groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species. [1]

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. [1]

Whales, bats, cheetah and human (all mammals) share similarities in the pattern of bones of forelimbs though these forelimbs perform different functions. Hence, in these animals show divergent evolution. [1]
