What is the study of the similarities and differences of body structures of different species?
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.
What is it called when structures that are similar in different species?
Homologous Structures. The structures derived from a common ancestor or from the same evolutionary or developmental origin are referred to as homologous structures.
