Anthropologist Shepard Krech points out that large animal species vanished even in areas where there is no evidence to demonstrate that Paleoindians hunted them.

人类学家谢泼德·克雷奇指出，即使在没有证据证明古印第安人猎杀大型动物的地区，大型动物也灭绝了。

Still, Krech attributes secondary if not primary responsibility for the extinctions to the Paleoindians, arguing that humans have produced local extinctions elsewhere.

克雷奇仍然认为古印度安人在灭绝上的责任即使不是主要的，也是次要的，他认为人类在其他地方造成了当地物种灭绝。

Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene.

Krech 断言广泛的气候变化确实发生在更新世末期，这与 Martin 排除气候变化作为解释的观点相矛盾。
