参考答案

正确答案：C
解析：本题问“短文最可能的标题是哪项”，属主旨题。短文的第一段和最后一段分别都点明了主题。在第一段中提到“Exactly why evolution has produced all this fussing，squawking and tapping is aquestion many biologists are trying to answer．”第二段接着说“Someday，that answer may shedsome light on the mystery of crying in human babies．‘It may point researchers in the right directionto find the causes of excessive crying，’…”也就是说科学家试图找出动物为什么嗷叫的原因，而这个问题的解决可能会揭示出婴儿啼哭的原因。最后一段中作者又提到“…these evolutionaryforces may have also shaped the cries of human babies．‘All primate infants cry．’Maestripieri said．‘It’s a very conserved behavior．It’s not something humans have evolved on their own．’”即科学家认为自然界的进化可能也导致了婴儿的啼哭。哭这种现象并不是人类独立形成的。因此。这篇文章最贴切的题目应该是：“动物身上找到对人类婴儿啼哭的提示”，故C正确。
