Question

Differentiate between homologous and analogous organs.

Answer 1

1. Homologous organs are present in organisms that have evolved from a common ancestor.
2. Organisms that have originated from different ancestors have analogous organs.

Homologous organs	Analogous organs
1. These are organs are structurally similar but have varied functions.	1. The organs that have different anatomy but functions alike are called analogous organs.
2. The homologous organs are developed in the related species.	2. The analogous organs do not develop in the related species.
3. Divergent evolution creates homologous organs.	3. Convergent evolution creates analogous organs.
4. For example, the limbs of frog are homologous to the limbs of humans.	4. For example, the fins in fishes are analogous to bird wings.
