Homology is the similarities that are present among the various species due to the fact that they are derived from the mutual ancestor. This similarity can be in their forms and structures, physiology, development from the same ancestor etc. The forelimbs of a number of organisms such as humans, bats, deer are homologous of each other as they all have the same number of bones.
They have an identical form of construction and depict common adaptive modifications. Take an Homologyof the wing of a bat and a whale’s flipper which are homologous to each other. Both of them form the forelimbs and have undergone adaptive modifications as one has to fly whereas the other has to swim.
