Detailed explanation-1: -Homologous organs are organs that evolve from the same ancestor. They have the same organ structure but different organ functions. Eg, the Forelimbs of humans, whales, cats, and dogs. Homologous organs are a result of divergent evolution .

Detailed explanation-2: -Homologous organs : The organs which have the anatomically same structure but are different in functions are called homologous organs. Examples of homologous organs are as follows: Mouth parts of cockroach, honey bee, butterfly. Forelimb of man, whale, bat, cheetah.

Detailed explanation-3: -Homologous organs have the same fundamental structure which they inherit from common ancestors. Thus, their origin is common but they are functionally different. For example, the forelimbs of frog, lizard, pigeon and whale have the same basic structural plan.

Detailed explanation-4: -Homologous organs are organs that have the same structural organization but different functional properties. They have a common ancestral origin. These organs are anatomically similar. Homologous organs are a result of divergent evolution as they evolved through a common ancestor.

Detailed explanation-5: -Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.
