Biological Evidence and the Fossil Record — Quiz

Question 7 • 26-27 - C - RUSD Biology in the Living Earth

A scientist makes the argument that she has found DNA evidence that shows that evolution does not exist. What would her evidence have to show for her to be correct?

Answer
A
Weak genetic similarities in closely related organisms and strong genetic similarities in distantly related organisms.
B
Strong physical similarities among closely related organisms and also among distantly related organisms.
C
Weak physical similarities among closely related organisms and also among distantly related organisms.
D
Strong genetic similarities in closely related organisms and weak genetic similarities in distantly related organisms.

Explanation

Evolution predicts that closely related organisms will generally have more similar DNA than distantly related organisms. To challenge that prediction, the scientist would need to find the opposite pattern: weak genetic similarities between close relatives and strong similarities between distant relatives. That is described by choice A.
