Document Summary
Paul martin"s book entitled twilight of mammoths chapter 2 summarizes his theory of overkill. The overkill theory claims that humans were responsible for the late pleistocene extinction of megafauna. Martin believes that there is a causal connection between the presence of people and the vanishing of numerous types of substantial warm-blooded animals. Martin argues that many forces could trigger extinction, well those that are evident in earths history such as meteor strikes, climate change, nutrient shortages, and diseases. Richard klein has an explanation and that is the ecological shock of human arrival (martin, 49). Martin strongly believes that climate change had nothing to do with the extinction of animals. By the 190s research information by paleontologist claude hibbard and by paleontologist in south america suggested that the large animals disappeared at a time when our species or its ancestors were present (martin, 49).
