Answer 1

Explanation:

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.
