LIFE SCIENCE

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: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Detailed explanation-3: -Analogous structures are structures which perform the same function, but have different ancestry. 3. We know that organisms must have evolved structures independently if they do not have a common ancestor.

Detailed explanation-4: -Analogous structures are similar structures in unrelated organisms. These structures are similar because they do the same job, not because they share common ancestry. For example, dolphins and sharks both have fins, even though they aren’t related.
