Define and explain the concepts of Homology and Adaptive radiation (divergent evolution).

(N/A) Homology refers to the similarity between organs of different animals based on common ancestry or common embryonic origin. These organs are built on the same fundamental structural pattern but perform varied functions and have different appearances. For example,the flippers of a seal,and the forelimbs of birds,bats,horses,and humans look different and perform different functions,but they exhibit the same underlying structural plan.
Adaptive radiation (divergent evolution) represents the evolution of new forms in several directions starting from a common ancestral type. This process leads to the development of diverse species adapted to different environments from a single common ancestor.
