Most mammals reach sexual maturity when their growth rates are in decline, whereas humans experience a growth spurt during adolescence. Whether apes experience an adolescent growth spurt is still undecided. In the 1950s, data on captive chimpanzees collected by James Gavan appeared devoid of evidence of an adolescent growth spurt in these apes. In a recent reanalysis of Gavan’s data, however, zoologist Elizabeth Watts has found that as chimpanzees reach sexual maturity, the growth rate of their limbs accelerates. Most biologists, however, are skeptical that this is a humanlike adolescent growth spurt. While the human adolescent growth spurt is physically obvious and affects virtually the entire body, the chimpanzee’s increased growth rate is detectable only through sophisticated mathematical analysis. Moreover, according to scientist Holly Smith, the growth rate increase in chimpanzees begins when 86% of full skeletal growth has been attained, whereas human adolescence generally commences when 77 percent of full skeletal growth has occurred. [br] The passage mentions which of the following as one of the reasons why most biologists remain skeptical that chimpanzees experience a humanlike adolescent growth spurt?
选项
A、Chimpanzees do not experience a demonstrable increase in growth rate until they are fully sexually mature.
B、The increase in growth rate that chimpanzees undergo at sexual maturity is less apparent than that of humans.
C、The increase in growth rate once regarded as a humanlike adolescent growth spurt in chimpanzees is too sporadic to be regarded as significant.
D、Not all chimpanzees undergo a calculable growth spurt.
E、Watt’s approach to analyzing data is considered to be highly unorthodox.
答案
B
解析
根据题干,大多数生物学家对黑猩猩的发育持质疑态度,定位到五六七,因此选项B正确。A项意味着黑猩猩完全性成熟时也是生长加速最明显的,但是根据文章的信息,黑猩猩在性成熟时的生长速度反而不明显。C项文中没提黑猩猩的生长是否是断断续续的。D项根据第六句,通过复杂的数学计算是可以得到黑猩猩的生长加速的。E项文中未提及。
