Question

Why are analogous structures a result of convergent evolution?

Answer 1

Hint: Different origins are present in the similarity of function and superficial resemblance of the structures in biology called analogy. Such as moths, wings of fly and birds are analogous because they developed independently as the adaptations as compared to the common functions present in the flying. It is distinct from the homology but evolutionary aspects of the analogy.

Complete answer:
Homoplasy is the phenomenon same as the cladistics and recurrent evolution of flight such as birds flying and bats that evolved in the capacity of flight. The related species involved in the different traits but opposite convergence is divergent of the evolution. Parallel evolution also known as a convergent evolution that occurred between the two independent species that are part of the same direction but independently that have similar characteristics such as the tree frog evolved in parallel form of the gliding frogs.
In plants many including the development of the ${C_4}$ in the photosynthesis, seed dispersal that obtained by the fleshy fruit and eaten by the animals or carnivorous are the instance part of the convergent evolution. The first time identification of the analogous structure introduced by Richard Owen by identifying the fundamental difference between the homologous and the analogies. Some attire sites like protease, one snail and fish insulin, Na, k-ATP and insect resistance to cardenolides and nucleic acid present at the molecular level in the analogous structure.

Note: The structure has similar types of functions and is not a part of the last common ancestors in the present group such as bats birds and pterosaurs but their forelimbs are homologous known as the convergent evolution. It is a type of independent evolution with a similar function but different periods of time.
