Because different mammalian species favor different environments, identifying and counting bones from prehistoric deposits in caves can reveal much about climatic changes. However, using large mammals’ bones can be problematic. Some species, such as
red deer
, are very adaptable—at home both on open grassland and in thick woodland. Moreover, some large-animal bones may have traveled considerable distances before being discarded: both carnivores and humans can have large hunting territories and bring home large animals quite unlike those near their den or campsite. Consequently, the bones of the small mammals found within cave sediments provide a better index of climate change: they are generally more numerous, the species are more sensitive to environmental conditions, and few travel far within their short lives. [br] The passage mentions “red deer” as an instance of an animal that
选项
A、is likely to be transported long distances by carnivores or humans
B、is frequently represented in prehistoric bone deposits
C、can be used to reconstruct past climate changes
D、can travel considerable distances over the course of its life
E、yields limited information about past environmental conditions
答案
E
解析
本题属于功能题,由定位句可见马鹿是那些具有适应性的动物的例子,因此选项E正确。正是因为适应性强才无法让人们推断出过去的气候。A项对应原因二,但是从文中看不出来马鹿本身是不是这种会被捕食者搬运很远的动物。B项没提及这些动物骨头的发现频率。C项显然说反了。D项对应原因二,但是从文中看不出来马鹿本身会不会走很远的距离。
