Last time we talked about passive habitat selection, like plants for example, they don't make active choices about where to grow.

上次我们讨论了被动的栖息地选择，比如植物，它们不会主动选择在哪里生长。

The biggest advantage of genetic selection, however, is probably not that it makes it possible to grow transgenic crops (" Frankenfoods "), but that it allows faster and more precise breeding.

但是，基因选择的最大优势或许不在于使得种植转基因作物(转基因食品)成为可能，而是他可以使育种更快和更准确。

Ironically, natural selection may even inadvertently provide some of the tools that cancer cells can use to grow.

讽刺的是，天择甚至可能无意中提供了癌细胞生长的工具。

Although most edible plants grow in the tropics, the main efforts to increase harvests have been based on a small selection of species from industrialised countries.
