Analogous structures

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.

1. Analogous Structures

2. What are Analogous Structures 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.

3. History of Analogous Structures Carolus Linnaeus first began the classification of species with taxonomy. He started grouping all similar looking species together. This led to the wrong classification of species because all similar looking structures are not evolved at the same time. Just because species look alike does not mean they are evolutionarily related.

4. Examples of Analogous Structures Analogous structures evolve due to convergent evolution when different organisms adapt to the same environment. 1- Wings of an insect and wings of a bird. 2- Fins of a fish and a penguin. 3- Limbs of humans, horses and dolphins.

5. Conclusion It does not depend only on appearance to determine which species are closely related, it takes more than just looks. However, analogous structures act as evidence that the theory of natural selection persists and the adaptations accumulate over time. Source:http :// explainry.com /biology/analogous-structures
