LIMITED TIME!!!! HELP PLEASE!!
Fossils of ancestors of the modern horses show a small, 4-toed, almost dog-like browsing animal named Eohippus. Over time, the horses got larger, lost toes, and changed to a grazing diet.

What is the best explanation for why this change occurred?

Select one:
A. The horses needed to run faster, so they ran more and their leg
and foot structure adapted.

B. The horses changed their environment to fit their needs for
survival.

C. The horses with traits most suited to the changing environment
survived.

D. The horses took the extra energy from a grazing diet and used it
to grow larger.
