As I've mentioned in previous columns, mutations - accidental changes to DNA - provide the raw material for evolution.
正如我在以往专栏中提及的那样，突变是DNA的意外变异，也是进化的原材料。
Despite so much evidence, evolution remains difficult to accept because it implies everything living is largely accidental.
尽管存在大量的证据，但进化论依然难以被接受，这是因为进化论中暗示世间万物都是以偶然的形式存在的。
This phenomenon is not a accidental things, it is the embodiment of the two saying way in the evolution of ci.
这一现象绝非偶然，正是词体这一散文化诗体两种言说质素于词体演进中的体现。
But mankind has caused lots of accidental changes as well, and these also offer opportunities to study evolution.
不过人类也造成了许多非刻意的环境改变，这些改变也为研究生物进化提供了机遇。
