The only fossilized bones of large prey found in and around settlements of early humans bear teeth marks of nonhuman predators on areas of the skeleton that had the most meat, and cut marks made by humans on the areas that had the least meat. The predators that hunted large prey invariably ate the meatiest parts of the carcasses, leaving uneaten remains behind.
If the information above is true, it provides the most support for which one of the following?
(A) Early humans were predators of small prey, not of large prey.
(B) Early humans ate fruits and edible roots as well as meat.
(C) Early humans would have been more effective hunters of large prey if they had hunted in large groups rather than individually.
(D) Early humans were not hunters of large prey but scavenged the uneaten remains of prey killed by other predators.
(E) Early humans were nomadic, and their settlements followed the migratory patterns of predators of large prey.
