According to a theory advanced by researcher Paul Martin, the wave of species extinctions that occurred in North America about 11,000 years ago, at the end of the Pleistocene era, can be directly attributed to the arrival of humans, i.e., the Paleoindians, who were ancestors of modern Native Americans. However, anthropologist Shepard Krech points out that large animal species vanished even in areas where there is no evidence to demonstrate that Paleoindians hunted them. Nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption. 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. Still, Krech attributes secondary if not primary responsibility for the extinctions to the Paleoindians, arguing that humans have produced local extinctions elsewhere. But, according to historian Richard White, even the attribution of secondary responsibility may not be supported by the evidence. White observes that Martin’s thesis depends on coinciding dates for the arrival of humans and the decline of large animal species, and Krech, though aware that the dates are controversial, does not challenge them; yet recent archaeological discoveries are providing evidence that the date of human arrival was much earlier than 11,000 years ago.

红色部分的话应该如何翻译比较恰当呢？

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.

我的翻译是：Krech也反驳了Martin把气候变化排除在外的理论，认为蔓延的气候变化的确发生在更新世末。求指正。

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

这个。。。不知道该怎么翻。

根据研究者Paul Martin所改进的理论，位于北美洲11,000年前，第四季冰川末期的种群灭绝可以被直接归因于人类的到达，即原始印第安人—当代美洲印第安人的祖先—的出现。但是，考古学家Shepard Krech指出大型动物种群即便在那些没有证据表明原始印第安人狩猎的地区也消失了。种群的灭绝并不仅限于大型动物：小动物、植物、甚至昆虫都消失了，可以推测这些消失应该不都是由于人类的消耗。Krech也反驳了Martin将气候的变迁这一因素排除在对上述动物种群灭绝现象的解释之外，他断言说大规模的气候变化的确在第四季冰川末期存在过。当然最终Krech仍然把原始印第安人归于上述灭绝的第二个主要理由，声称人类造成了其他地区的当地的种群灭绝。但是根据历史学家Richard White的描述，即使把人类活动作为第二主要理由仍然缺乏证据支持。White发现Martin的论文依赖于人类到达和大型动物种群消失的偶然时间巧合，而Krech尽管意识到了上述时间是有争议的但是并没有进一步去考证它们；但是最近的考古学发现提供了很多证据，这些证据表明人类的到达比11,000年前要早得多。
