There's an idea that says the tropics are so well suited to the creation of new species that it's like an engine for biodiversity.

一个观点是，热带地区适合新物种产生，它就像产生新物种的引擎。

It's possible that evolution is actually working on overdrive here near the equator, the speciation, the creation of new species by various natural forces, actually happens faster near the equator.

在赤道附近，进化很可能加速进行，需要多种因素共同促成的新物种在赤道附近能更快出现。
