问题 From the first paragraph, we can deduce that ______.
On the forth paragraph, the word "extinction" in the sentence "Climate changes caused the extinction of many elephant species, but human influence has also taken its toll." means ______.

选项 A、evolution
B、distinction
C、production
D、depopulation
