Question

what is the difference between analogous and homologous organs

Answer 1

Homologous Organs:

1. They differ morphologically.

2. They have similar internal structure.

3. They develop in related organisms.

4. Stages in the development are similar.

5. They perform different functions.

6. They have similar developmental pattern.

7. Homologous organs show adaptive radiation (divergent evolution).

Analogous Organs:

1. They show superficial resemblance.

2. Their internal structure is quite different.

3. They develop in unrelated organisms.

4. Stages in the development are different.

5. They have similar functions.

6. They have dissimilar developmental pattern.

7. Analogous organs show convergent evolution.

Answer 2

The diff. Between analogous and homologous organs are

Analogous-organs with different basic design structure but same function

They do not have common ancesters

Homologous - with common basic design structure but different function

They have common ancestor
