Question

what is a homologous ??​

Answer 1

The homologous organs are similar in form (or are embryologically same), but perform different functions in different organisms. These provide strong evidence in the favour of evolution.

The homologous organs are similar in form (or are embryologically same), but perform different functions in different organisms. These provide strong evidence in the favour of evolution. For example - The bone structure observed in wings of birds, wings of bats, flippers of dolphins, and arms of human beings resemble with each other. Though they look strikingly different on the outside and though they vary in function but they are very similar in skeletal structure. Thus in these animals, the same structure developed along different directions due to adaptations to different needs. This represents a case of divergent evolution.

Answer 2

Answer:

• Homology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.Homologous,” in biology, means a similarity in internal or chromosomal structures. With internal structures, homology indicates organs that have similar positions, structures, or evolutionary origins. It's important to note, however, that organs do not have to have the same function to be homologous.
• In organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by -CH2.
