Answer 1

Homologous Structures have similar morphology, embryology and anatomy etc. but are dissimilar in their functions.Analogous structures are those structures in different species which perform the same function, have similar appearance and structure but are not evolved together; therefore do not share a common ancestor.

I hope you are satisfied to my answer so please follow me

Answer 2

HOMOLOGOUS ORGANS:

》The organs which have similar structure or have same morphological structure but performs different functions are known as Homologous Organs.

》Homology indicates that the organism have common ancestry.

》It is a result of divergent evolution.

》Examples includes : Forelimbs of man, cheetah, bats, etc.

ANALOGOUS ORGANS:

》The organs which have different morphological structure but performs same functions are known as Analogous Organs.

》Analogy does not indicate that the organism had common ancestry.

》It is a result of convergent evolution.

》Examples includes : Wings of birds and insects.
