Detailed explanation-1: -The organs found in different organisms which have a common origin and same basic structure but differ in the functions they carry out are called homologous organs. Examples of homologous organs include the forelimbs of a man, the forelimbs of a cat, the flippers of a whale, and the wings of a bat.

Detailed explanation-2: -Wings of a bat and forelimbs of a horse are considered homologous because they have a common origin and are built on the same fundamental pattern, but perform varied functions and have varied appearances.

Detailed explanation-3: -An example of homologous organs is our arm and a dog’s foreleg, our teeth and an elephant’s tusks, potato, and runners of grass.

Detailed explanation-4: -As shown in the next image, the bones in the wings of bats and birds, the arms of humans, and the front leg of a horse are homologous structures.
