And every time a cell is hijacked, little mistakes are made in copying the genetic material.

每次劫持细胞时，复制遗传物质时都会出现小错误。

In a study from 2014 by Pam Mueller and Danny Oppenheimer, students typing wrote down almost twice as many words and more passages verbatim from lectures, suggesting they were not understanding so much as rapidly copying the material.

在帕姆·穆勒和丹尼·奥本海默2014年发表的一项研究中，课堂上打字的学生写下了几乎两倍的单词和更多的逐字段落，这表明他们并不完全理解，只是在快速抄写材料。
