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 had become extinct. Yet humans cannot have been a factor in the species' extinctions, because there is no evidence that the humans had any significant contact with the mammals. Further, archaeologists have discovered numerous sites where the bones of fish had been discarded, but they found no such areas containing the bones of large mammals, so the humans cannot have hunted the mammals. Therefore, some climate change or other environmental factor must have caused the species' extinctions.

针对这个可不可以这样写：
The arguer assumes that there is no evidence that humans had contact with the mammals, so that humans are not responsible for extinction.

开头直接说出题目的结论，即大型哺乳动物的灭绝是因为天气的原因而非人为因素！
