Comparative anatomy is the study of similarities and differences in the anatomy of different species as it is closely related to evolutionary biology and phylogeny (the evolution of species) and it serves as a evidence for evolution. It includes the change, adaptation and mutation of species, the invasion of new territories and the species compatibility with the surroundings. The adaptation in terms of comparative anatomy is defined as the genetic and physiological changes that occur due to pressures or changes in an animal’s environment. Examples due to changes in adaption are Forelimb of humans used for manipulating etc. The important concepts of Comparative anatomy are Homologous structures and Analogous structures. This includes the Ontogenesis-development of individuals and the phylogenies-ancestral histories of individuals. This also involves the study of ecology, embryology, genetics, molecular biology, biodiversity, Pale biology.
