what do you mean by homologous organ ? Explain in brief how Homologous
Answers
Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function. The most important part, as hinted by their name, is that they are structurally similar.
Answer:
Homologous organs are defined as the organs of different animals that are having a similar structure but differ in their functions. The structure of the two different animals resemble but the functions of their organs vary.
Example
Example of homologous organs are the forelimbs of frog, man, and the flippers of the whale.
The structure of these animals are the same but the function in a different manner. The flippers are used for swimming, the forelimbs of frogs are used for jumping and propping, and the forelimbs of man are used for writing, eating, holding things, etc. Having a similar structure shows that all these animals have a common ancestor.
