Question

how do homeologous organ represent divergent evolution? Explain with the help of suitable example.​

Answer 1

Answer:

Homologous organs are the organs having fundamental similarity in structure and origin but different function. They represent a case of divergent evolution. ... Thus, in these animals, the same structure developed along different directions due to adaptations to different needs.

Explain with the help of a suitable example. For example in plants the thorn and tendrils of Bougainuillea and Cucurbita represent homology. Both the thorn and the tendril have a common ancestor but have evolved to perform different function in different organism. ... Thus, it represents divergent evolution.

Answer 2

Answer:

Whales, bats, cheetah and human (all mammals) share similarities in the pattern of bones of forelimbs. Though these fourlimbs perform different function in these animals, they have similar anatomical structure. All of them have humerus, radius, ulna, carpals, meta carpals and phalanges in their forelimbs. Hence, in these animals the same structure develops along different directions due to adaptation to different needs. This is divergent evolution and DJ structures are homelogus.

Homology indicates common ancestar. Other examples are vertebrate hearts or brains. The thorn and tendrils of Bougainvillea and cucurbita represent homology which is based on divergent evolution.
