LIFE SCIENCE

Detailed explanation-1: -Organs with similar structure and origin are called homologous organs.

Detailed explanation-2: -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-3: -Structures which have a common basic structure but perform different functions are called homologous structures. For example, forelimbs of reptiles, amphibians and mammals. Yes, they have common ancestor but variously modified to carry out different activities. Analogous organs have different basic structure.

Detailed explanation-4: -Comparative Anatomy Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Detailed explanation-5: -Evolutionary biologists that study genetics of organisms noticed similarities in structures of these organisms even when the function was not the same. These structures are called homologous because they have the same organization, but different purpose.
