Micro‐wear patterns found on the teeth of long extinct specimens of the primate species australopithecine may provide evidence about their diets. For example, on the basis of tooth micro‐wear patterns, Walker dismisses Jolly’s hypothesis that australopithecines ate hard seeds. He also disputes Szalay’s suggestion that the heavy enamel of australopithecine teeth is an adaptation to bone crunching, since both seed cracking and bone crunching produce distinctive micro‐wear characteristics on teeth. His conclusion that australopithecines were frugivores (fruit eaters) is based upon his observation that the tooth microwear characteristics of east African australopithecine specimens are indistinguishable from those of chimpanzees and orangutans, which are commonly assumed to be frugivorous primates.
题目：
The passage suggests that Walker’s research indicated which of the following about australopithecine teeth?
(A) They had micro‐wear characteristics indicating that fruit constituted only a small part of their diet.
(B) They lacked micro‐wear characteristics associated with seed eating and bone crunching.
(C) They had micro‐wear characteristics that differed in certain ways from the micro‐wear patterns of chimpanzees and orangutans.
(D) They had micro‐wear characteristics suggesting that the diet of australopithecines varied from one region to another.
(E) They lacked the micro‐wear characteristics distinctive of modern frugivores.
疑惑这道题的E。
原文是说：Walker觉得这个australopithecines和 chimpanzees and orangutans的tooth microwear characteristics一样，因为chimpanzees and orangutans主要吃水果，所以australopithecines也主要吃水果。
这里E表达的意思也是说australopithecines和吃水果的tooth microwear characteristics没有区别。
那这个选项错在哪里呀？还是modern有什么问题？
新人求解！谢谢~

"Distinctive of" is the same as "characteristic of" or "belonging to." (E) says that australopithecine teeth lacked the micro-wear characteristics characteristic of modern frugivores. In other words, australopithecine teeth didn't have the same micro-wear characteristics that the modern frugivore teeth have.
Walker said no such thing. In fact, Walker concluded that australopithecines were frugivores because he had observed that the tooth micro-wear characteristics of east African australopithecine specimens are indistinguishable from those of the primates that are commonly assumed to be frugivores. That's why we eliminate (E).
