Recent studies of the Philippine fruit bat fauna have confirmed some previous hypotheses regarding bats on oceanic islands: for example, species richness [the number of different species in a particular area] and abundance are generally highest in the lowlands and decrease with increasing elevation. With few exceptions, each endemic species [species native to a particular place] is restricted to the modern islands that made up a single island during periods of low sea level,
and genetic differentiation has been influenced by the ecology of the species and the current and past geographic and geological conditions.
However, far more previous hypotheses have been overturned than supported. Some endemic Philippine species use disturbed habitat as extensively as nonendemic species that are widespread in Southeast Asia. Levels of genetic variation within all species are high, not low, and rather than showing evidence of an intrinsic vulnerability to extinction from natural causes, independent lineages of these bats have persisted in rather small areas for very long periods of time (often millions of years) in spite of frequent typhoons and volcanic eruptions. While colonization from outside areas has clearly contributed to the high species richness, speciation within the archipelago has contributed at least a quarter of the total species richness, including many of the most abundant species.

选项
A、identify a finding from the Philippine fruit bat studies that will have a significant impact on how oceanic bats generally are viewed
B、point out a hypothesis that has been the subject of considerable disagreement among researchers studying oceanic bats
C、present evidence that is difficult to reconcile with other recent findings regarding the Philippine fruit bat
D、illustrate a widely held view about oceanic bats generally that was confirmed by the Philippine fruit bat studies
E、identify a feature of the Philippine fruit bat that does not appear to apply to oceanic bats generally
答案
D
解析
本题属于功能题,定位句3s版本,即“被证实的假说”,因此选项D正确。A项黑体部分不是发现,而是最近关于菲律宾水果蝙蝠的发现所证实的假说。B项黑体部分没提disagreement。C项既然黑体部分是被菲律宾水果蝙蝠发现所证实的,也就意味着黑体部分不是与最近发现不可调和。E项黑体部分没提feature。
