托福阅读文本：
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.
Perhaps the human species was driving others to extinction long before the dawn of history.
Hunter-gatherers may have contributed to Pleistocene extinctions in more indirect ways. Besides
overhunting, at least three other kinds of effects have been suggested: direct competition,
imbalances between competing species of game animals, and early agricultural practices. Direct
competition may have brought about the demise of large carnivores such as the saber-toothed cats.
These animals simply may have been unable to compete with the increasingly sophisticated
hunting skills of Pleistocene people.
Human hunters could have caused imbalances among game animals, leading to the extinctions
of species less able to compete. When other predators such as the gray wolf prey upon large
mammals, they generally take high proportions of each year's crop of young. Some human hunters,
in contrast, tend to take the various age-groups of large animals in proportion to their actual
occurrence. If such hunters first competed with the larger predators and then replaced them, they
may have allowed more young to survive each year, gradually increasing the populations of
favored species. As these populations expanded, they in turn may have competed with other game
species for the same environmental niche, forcing the less hunted species into extinction. This
theory, suggests that human hunters played an indirect role in Pleistocene extinctions by hunting
one species more than another.
