What is at the top of the list of species extinctions?
Researchers at the Royal Botanic Gardens and Stockholm University recently found that at least 571 plant species have gone extinct since 1750. The figure was calculated when scientist Rafael Govaerts reviewed all publications on plant extinctions over more than 30 years and found the number to be four times more than the current listing of extinct plants. It’s also twice the number of all bird and mammal extinctions combined.
选项
A、Plants.
B、Birds.
C、Mammals.
D、Insects.
答案
A
解析
根据新闻定位句可知,自1750年以来,至少有571种植物已经灭绝,这个数字是目前已灭绝植物名单上的四倍多,也是鸟类和哺乳动物灭绝总数的两倍。故选A。
