▶ Your Answer :
First, the speaker says that the most problematic theory is the one about low reproducive rate. Having low fertility rate doesn't mean the species are doomed to extinction. For example,Koala bears have less offsprings than Diprotodon, but there are no signs of extinction to them. This casts doubt on the reading passage's claim that the low number of offspring made Diprotodon to be vulnerable to the environment, ending up to extinction. Next, the speaker argues that the shortage of food is not the cause of Diprotodon's disappearance. The early humans' use of fire actually led to an increase of soil's nutrition. Moreover, there were alternative foods that Diprotodons could have. This challenges the reading passage's point that elimination of Diprotodon's only diet, the saltbush, caused them to extinct. Finally, the speaker points that the explanation about Diprotodon being killed by predators is groundless. To be specific, because of the great size of Diprotodon, there were not many predators that were deadly to them. They actually coexisted with preadators for many years. This argues aganist the reading passage's claim that fossils with marks of predators are clues that support Diprotodon extinction was made by predators.
