Homologous
Organs are those which are similar in their morphology, anatomy,
genetics and embryology but dissimilar in their functions.
These structures are inherited from a common ancestor; they have similar developmental pattern in the embryos; they have the same type of bones, blood vessels, nerves, muscles etc. but they have to do dissimilar functions in different animals.
The forelimbs of higher vertebrates are examples of homologous organs. The forelimbs of a bird, whale, cat, a horse, a bat, mole, a monkey and man are doing different functions; but they have similar anatomy in all the animals.
