Question

which part is taken homologus evidence in the following animals a. man B. cheetah c. Whale d. bat​

Answer 1

They share a common ancestor

The bones of forelimbs of whale, bate, cheetah, and man are similar in structure because they are homologous organs. The organs which have the same fundamental structure but are different in functions are called homologous organs. These organs follow the same basic plane of organization during their development. But in the adult condition, these organs are modified to perform different functions as an adaptation to different environments. The homologous structures are a result of divergent evolution. Homology indicates common ancestry.

So, the correct answer is 'They share a common ancestor'.

Answer 2

The limbs of man, cheetah, whale and bat are taken as homologous organs as they have the same structure but are differently adapted for different functions…. ^.^
