NEET BIOLOGY

Detailed explanation-1: -comparative anatomy, the comparative study of the body structures of different species of animals in order to understand the adaptive changes they have undergone in the course of evolution from common ancestors.

Detailed explanation-2: -Comparative anatomy refers to the study of the similarities and differences in the anatomy of two species. Generally, it involves comparing the body structures of two species as seen in evolutionary biology and phylogeny. Evolution, in a population, refers to a genetic modification occurring over a period of time.

Detailed explanation-3: -The three structures of comparative anatomy are as follow: Homologous structures. Analogous structures. Vestigial structures.

Detailed explanation-4: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Analogous structures are structures that are similar in unrelated organisms. Comparative embryology is the study of the similarities and differences in the embryos of different species.

Detailed explanation-5: -Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
