  Many prehistoric people subsisted as hunters and gatherers。 Undoubtedly, game animals, including some very large species, provided major components of human diets。
   An important controversy centering on the question of human effects on prehistoric wildlife concerns the sudden disappearance of so many species of large animals at or near the end of the Pleistocene epoch。
   Most paleontologists suspect that abrupt changes in climate led to the mass extinctions。 Others, however, have concluded that prehistoric people drove many of those species to extinction through overhunting。
   In their "Pleistocene overkill hypothesis," they cite what seems to be a remarkable coincidence between the arrival of prehistoric peoples in North and South America and the time during which mammoths, giant ground sloths, the giant bison, and numerous other large mammals became extinct。
