Question

Which of the following best describes how comparative anatomy can be used to determine the evolutionary relationship between two organisms?

Organisms that have a great deal of physical similarity are more likely to share a common ancestor than two organisms with few physical traits in common.
Comparing the physical traits of two organisms makes it possible to determine how long ago they shared a common ancestor.
Studying the physical differences between two organisms will show which organism evolved from the other.
Two species that have few physical traits in common do not share a common ancestor and most likely evolved from different species.

Answer 1

Two species that have few physical traits in common do not share a comman ancestor and most likely evolved from different species.

Step-by-step explanation:

Answer 2

The correct option is D.

Step-by-step explanation:
