GRE Argument 165重新选题
写作题目
收起Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct. Previous archaeological findings have suggested that early humans generally relied on both fishing and hunting for food; since archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, it is likely that the humans also hunted the mammals. Furthermore, researchers have uncovered simple tools, such as stone knives, that could be used for hunting. The only clear explanation is that humans caused the extinction of the various mammal species through excessive hunting.
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.

大约7000年前人类到达了Kaliko岛,在3000年内曾经生活在Kaliko岛的树林中的大型哺乳动物绝大多数已经灭绝了。然而人类并不是导致这些物种灭绝的因素,因为没有证据表明人类与这些哺乳动物有很多接触。而且,考古学家发现一些有大量鱼骨被抛弃的场所,而他们并没有发现存在大型哺乳动物骨头的类似场所,因而人类并没有猎杀这些哺乳动物。因此,一定是一些气候上的变化或其他环境因素导致了这些物种的灭绝。
