So they're the essentially the musical equivalent of what geneticists call a " neutral mutation, " one that doesn't alter an organism's fitness.

因此，遗传学家说的“中和突变”在音乐界中大概就是这种小突变，而这种突变不会改变有机物的健康。

You do, you have built-in redundancy, which means, like, you have built-in chances for evolution to get to work and start to modify things through neutral mutations, but some of them work.

内在的冗余意味着你有内在的机会让进化开始起作用，并开始通过中性突变来修改事物，但其中一些是有效的。
