比如这道题~

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.


错误推理: 1.鱼骨的发现说明哺乳动物被人类捕猎 2.小刀是用来捕猎的
问题:

1.我是只用自己提出其他可能的mammal灭绝的原因(气候原因, 其他天敌捕猎)就可以了呢, 还是必须也解释一下题目中间提到的那几个错误结论呢?
2.这里鱼不属于哺乳动物吧? 有的提纲写得这里的问题是鱼可能是被其他动物吃掉的而不是人类,好像没考虑鱼并非哺乳动物? 这个错误需要提吗?

你要指明文中的解释有什么问题，这点很重要
