Explain the terms analogous and homologo | Class 10 Science Chapter Heredity and Evolution, Heredity and Evolution NCERT Solutions

Question:

Explain the terms analogous and homologous organs with examples.

Answer:

Homologous organs are the organ whose origin is similar (or are embryologically similar) but perform different functions. Such as the forelimbs of humans and the wings of birds look different externally but their skeletal structure is similar. It means that their origin is similar (as wings in birds are modifications of the forearm) but functions are different - the wings help in flight whereas human forearms help in various activities.

Analogous organs, on the other hand,  are those organs that have different origins but perform similar functions.such as, the wings of a bird and a bat are similar in function but does not mean that these animals are closely related. wings of a bat are the folds of skin that are stretched between its fingers whereas the wings of birds are present all along the arm, these organs are analogous organs.
