These are physical features shared by organisms with common ancestry; they may have the same structure. What are these strucrures?

The correct answer will be - homologous structures

Explanation:

The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.

Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.

The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures. "

Thus, homologous structures are the correct answer.
