Question

What does the presence of homologous structures in different organisms suggest?

Answer 1

The answer is “common ancestry”

Answer 2

Answer:

The correct answer is option 2. Common ancestry.

Explanation:

The homologous structure is the structure that has a similar anatomical structure or underlying skeleton and can perform a different function in different organisms.

Homologous structures are similar in different organisms because they diverge from a common ancestor. All organisms that have homologous structures are considered to have a common ancestry. for example, human arm, dogs forearm, bat's wing all have a similar skeleton structure  

Thus, the correct answer is option 2. Common ancestry.
