But how could scientists spend so many years studying these lichens—and still miss this crucial third species?

但是，科学家们怎么会在研究地衣多年后仍未发现这至关重要的第三物种？

The microbes from the third species, Onthophagus batesi, significantly decreased the growth of all nine.

第三种微生物 Onthophagus batesi 显著降低了这九种细菌的生长速度。

Eventually, these AI progenies continued  and developed this process, producing what became a third, new species: the Naos, the first  conscious descendants of originally AI beings.

最终， 这些人工智能后代继续并发展了这一过程，产生了第三个新物种：Naos，即原始人工智能生物的第一个有意识的后代。
