This measure protects teachers' and students' rights to present and hear “the full range of scientific views regarding biological and chemical evolution, ” but it does little in practice.

这个法规保护了老师和学生提出、倾听“关于生物和化学进化论的所有科学观点”的权利，但并没怎么落实。

There are many theories about how exactly it began, some believe simple life arrived from a meteorite, while others think chemical evolution started with compounds reacting to heat, or perhaps they were struck by lightning.

关于它究竟是如何起源的理论也有很多，一些人认为简单的生命是来自陨石，而另一些人认为化学进化始于化合物对热的反应，或者可能是被闪电击中。
