Question

How does comparative anatomy support the idea that organisms share ancestors?

Answer 1

Step-by-step explanation:

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.

Answer 2

It allows you to observe both morphological and functional changes in organs and organ systems. Specific structures may be unique to a particular lineage of organisms, this would only be revealed through the study of comparative anatomy.

Comparative anatomy has applications in multiple fields; from evolution and taxonomic studies right through to physiology and ecology.
