Darwin made extensive use of comparative anatomy in advancing his theory, and it in turn revolutionized the field by explaining the structural differences between species as arising out of their evolutionary descent by natural selection from a common ancestor. Since Darwins time, the study of comparative anatomy has centred largely on body structures that are homologousi.e., ones in different species that have the same evolutionary origin regardless of their present-day function. For example, if we observe the limbs of humans and other primates, we can deduce that they evolved from a common ancestor. Gross anatomy- systemic or region-wise study of human body parts and organs.
