Detailed explanation-1: -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-2: -We can say that similar habitat has resulted in selection of similar adaptive features in different groups of organisms but towards the same function. B. Homologous organs – Forelimbs of man, cat, bat and whale are homologous organs.

Detailed explanation-3: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not hav e the same function in the descendants.

Detailed explanation-4: -Homologous structures homologous-structures The similar construction of these appendages indicates that these organisms share a common ancestor. Analogous structures, in contrast, have the same function but do not necessarily derive from the same ancestry, as some analogous structures evolved convergently.

Detailed explanation-5: -Homoplasy is the development of organs or other bodily structures within different species, which resemble each other and have the same functions, but did not have a common ancestral origin. These organs arise via convergent evolution and are thus analogous, not homologous to each other.
