And so being able to have a precise chronometer we can relate things like speciation events, or dispersals of various life forms.

我们可以通过一个精确的时钟将各种事件关联起来，比如种起源或各种命形式的分散等。

Sheela Turbek: Normally, for speciation to occur organisms have to be confined to different geographic regions in order to accumulate genetic differences.

Sheela Turbek：通常情况下，要发种形，须局限于不同的地理区域，以便积累遗传差异。

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的新种在赤道附近能更快出现。

I mean just like you see a lot of speciation on Islands, these plastic wraps are essentially little islands and they're going to be long-term Islands because that plastic degrades so slowly.

我的意思是，就像你在岛屿上看到的许多种一样，这些塑料薄膜本质上是小岛，它们将是长期的岛屿，因为塑料降解得很慢。

Who knows? I mean just like you see a lot of speciation on Islands, these plastic wraps are essentially little islands and they're going to be long-term Islands because that plastic degrades so slowly.
