Question

Difference between homologous and analogous organs biology discussion

Answer 1

This answer is best understood in terms of ancestry and function. Analogous structures have different evolutionary ancestries but they have the same function. Examples of these types of structures are the wings of birds, bats and insects. Homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism. A dolphin’s flipper, a human arm and the leg of a cat are examples of homologous structures. Analogous structures represent convergent evolution, where natural selection drives species to have the most efficient and practical structures for specific functions.

Answer 2

$\huge\red{Homologous}$ is an organism which has same structure but have different function.

Example :-

Limb of human and whale.


$\huge\red{Analogous}$ is an organism which has same function but have different structure.

Example :-

Flipper of whale and penguin.
