它们已经在深海热泉区的边缘处繁衍生息，那里喷涌着含有毒化学物质的过热海水。

They've adapted to thrive at the edge of hydrothermal vents, which spew superheated water saturated with toxic chemicals.

因此，在某些潮湿的地区，也许是海底热泉喷口附近，或浅水池塘岸边的粘土中，有机分子开始了自我复制。

So in some wet place, maybe near an undersea hydrothermal vent, maybe in the clay on the shore of a shallow pond, organic molecules started to replicate.
