Over the last century, paleontologists have used small differences between fossil specimens to classify triceratops into sixteen species. This classification is unjustified, however, since the specimens used to distinguish eleven of the species come from animals that lived in the same area at the same time.
Which of the following, if true, would enable the conclusion of the argument to be properly drawn?
(A) Not every species that lived in a given area is preserved as a fossil.
(B) At least one individual of every true species of triceratops has been discovered as a fossil specimen.
(C) No geographical area ever supports more than three similar species at the same time.
(D) In many species, individuals display quite marked variation.
(E) Differences between fossil specimens of triceratops that came from the same area are no less distinctive than differences between specimens that came from different areas.
答案給C
題目是說古生物學者化石樣本間微小的差異將三角龍分成16種 但這種分類方式是不妥當的 因為用來分類的化石 有11個來自相同時代的同一地區
C是說[沒有一個地理區域可以同時維持超過三個類似的物種生存]
看不出兩者的關係耶
如果是說[沒有一個地區可以同時維持超過三個不同物種的生存]的話 那還可以解釋說古生物學家在同一時代的同一地區採用了11個樣本 可是實際上最多只能分出三種 所以這種方式是不妥當的
可是現在是說[沒有一個地理區域可以同時維持超過三個類似的物種生存]
感覺還ok呀 因為11個樣本還是有它們的判斷分類價值呀(雖然3個一樣 其它8個還是可以分類)
煩請各位高手指點一下吧
