[求助]新东方语法教材Page57,No.11

According to scientists at the Uni of California, the pattern of changes that have occurred in human DNA over the millennia indicate the possibility that everyone alive today might be descended from a single female acestor who lived in Africa sometime between 140,000 and 280,000 years ago.

D) indicates that everyone alive today may be a descendant of a single femal ancestor who

E) indicates that everyone alive today might be a descendant of a single femal ancestor who

正确答案是D。我理解might/may在这里是表示推测，与时态无关，所以采用了对情态动词尊重原文的选项，选E。 请NN们给解释一下。根据正确答案，may与today搭配，那不就改变了推测的程度，不尊重原文了。感谢大家

记得没错的话 选项E  用了个descedant from 搭配   楼主是否把E选项给打错了

a descendant of 是固定搭配  

对比排除E 选D
