在前一章中，我们已经强调了双氧的出现给现存的厌氧生物带来的危险，以及它们进化出的处理这些问题的方法。然而，这只是故事的一部分，如果它在这里结束，我们和我们所知道的世界将不复存在。相反，发生的事情相当引人注目；因为生命抓住了自由二氧存在的机会，从食物中提取能量的效率提高了许多倍。正如我们将看到的，这种有氧、氧化代谢反过来又为生长和多样化开辟了许多新的机会。
In the preceding chapter, we have emphasized the dangers that the advent of dioxygen presented to the existing anaerobic organisms, and the ways they evolved to deal with the problems. However, this is only part of the story and were it to have ended here, we and the world we know would not exist. What happened instead was quite remarkable; for life seized upon an opportunity presented by the presence of free dioxygen to become many-fold more efficient in extracting energy from foodstuffs. As we shall see, this aerobic, oxidative metabolism opened in turn a multitude of new opportunities for growth and diversification.
