PrepTest 83, Section 3, Question 10
The prehistoric fish Tiktaalik is the earliest known animal with fingers. Since variations were so great among prehistoric fish species, Tiktaalik would not have stood out as unusual at the time. However, Tiktaalik's fingers were an important development in animal evolution because it is likely that Tiktaalik is an ancestor to the many land animals with fingers.

The statements above, if true, most strongly support which one of the following?
Tiktaalik likely used its fingers to move on land.
Tiktaalik's fingers were its only feature to play a significant role in the development of modern land animals.
Tiktaalik is not the ancestor of any currently surviving fish species.
No fish without fingers would ever be able to move on land.
The evolutionary significance of Tiktaalik could not be determined just through comparison to fish species of its time.
