The authors would be most likely to agree with which one of the following statements?

Text and explanation?
Can someone explain why E is correct here and what evidence in the passage they used to arrive at the correct answer choice? My gut instinct is that E is unsupported because the passage seems to be saying the opposite? Thanks in advance.

Hi all,
We have just put a group of instructors on the message boards so that your questions will be answered promptly going forward!
On this one, take a look at the final paragraph. The author speaks of the human digestive system and how its evolution has been traditionally explained by adaptations to a high raw-meat diet. The author proposes a different explanation for the evolution, the adaptation to cooked meat. While this is what the author believes, we still must consider the logical force. The author says the cooking model explains the digestive system “at least as well” as the raw-meat model. This is far from definitive proof that the cooking model has better explanatory power. The author even goes on to say that further testing is needed (line 56).
A similar thing happens in paragraph two in which the author talks about our teeth and jaw. The author does state, in discussing the decrease in jaw and teeth size 100,000 years ago, that, “we suggest that this was a consequence of eating cooked food.” The author even provides some support with a correlation between dental reduction and cooking technology (lines 35-38). However, the author never indicates that there is definitive proof for their conclusion. See line 39, for example, in which the author speaks about another explanation for the impact of cooking that is “also possible” (line 38).
Answer choice E is saying that there is not yet definitive support. The author seems to believe that humans could have developed biological adaptations, perhaps even that they likely did, but we have no reason to believe that the author thinks there is definitive evidence for it. Thus, E is the correct answer.
