What is analogous organs and what is homologous organs?

Question

Answer

Analogous organs are the organs having different structure but same functions for example -->Wings of insects and Wings of bird.
Homologus organs are the organs having same structure but different function for example--> Dolphin flipper and bird wing.

Answer

Analogous organs:- Organs having different structure and origin but similar characteristics.
Examples:- Wings of bats, butterflies etc..

You may came to know that the wings of bats and wings of butterflies having similar characteristics, means, they use their wings for flying. But they having a very different in their structures.

Homologous organs:- Organs having same structure and origin but different in their characteristics.
Examples:- Forelimbs of Amphibians, Reptiles etc..

You came to know that the Forelimbs of Amphibians and Forelimbs of Reptiles having a very similar in their structures but in their functions, they are totally different.

Answer

Analogous organs are the organs having different structure but same fuction .

Answer

Analogous Organs and Homologous Organs:

Analogous Organs:
Analogous organs are those organs that have a similar function but have different evolutionary origins. These organs are formed in different species in response to the same environmental pressures and needs. The anatomy, structure, and development of these organs may differ from each other, but they serve the same function. The wings of birds and insects are a good example of analogous organs. They both serve the same function of flying, but their anatomy and structure are different.

Homologous Organs:
Homologous organs are those organs that have a similar structure and evolutionary origin but may have different functions. These organs are formed from the same ancestral structure in different species due to the process of divergent evolution. The anatomical, structural, and developmental similarities of these organs indicate a common ancestry. The forelimbs of humans, cats, whales, and bats are a good example of homologous organs. They have the same bone structure, but they serve different functions in different species.

Difference between Analogous and Homologous Organs:

1. Origin:
Analogous organs have different evolutionary origins, while Homologous organs have the same evolutionary origin.

2. Structure:
Analogous organs have different anatomical structures, while Homologous organs have similar anatomical structures.

3. Function:
Analogous organs have the same function, while Homologous organs may have different functions.

4. Evolution:
Analogous organs are formed in different species due to convergent evolution, while Homologous organs are formed in different species due to divergent evolution.

Conclusion:
Analogous and Homologous organs are two concepts that help us understand the evolution and diversity of life on earth. While Analogous organs have different evolutionary origins and serve the same function, Homologous organs have the same evolutionary origin and may have different functions. Understanding these concepts is essential to understand the evolutionary relationships between different species.
