Before the Ordovician, terrestrial life was probably limited to microbes.

在奥陶纪之前，陆地生命 可能仅限于微生物。

Because, those tiny plants set up the conditions for more sophisticated terrestrial life to evolve.

因为，那些微小的植物为更复杂的陆地生命的进化创造了条件。

But another of the Moon's gravitational effect on our planet is directly responsible for nothing less than the continued survival of terrestrial life itself.

然而月球对我们星球的另一个引力作用，是直接作用陆地生存的生命。

These microbes were most likely the only terrestrial life around, and had been for several billion years.

这些微生物很可能是周围唯一的陆地生命，并且已经存在了数十亿年。

They are an incredibly adaptable and distinct life-form, playing a key role in terrestrial life on the planet.

它们是一种适应性极强且与众不同的生命形式，在地球上的陆地生命中发挥着关键作用。

Oxygen levels in the Devonian and Carboniferous periods, when terrestrial life first bloomed, were as high as 35 percent (as opposed to nearer 20 percent now).

在陆地生命大幅度增加的泥盆纪和石炭纪，空气中的氧的浓度高达35%（现在是将近20%）。

Sure, the first land plants were the spark that wreaked havoc on ocean biodiversity, but they also paved the way for all the terrestrial life that came after.

当然， 第一批陆地植物是对海洋生物多样性造成严重破坏的火花，但它们也为后来的所有陆地生命铺平了道路。

There, they released their spores, taking advantage of the tide to disperse those spores, like their ancestors had done for generations, and gradually transitioning from aquatic to terrestrial life.

在那里，他们释放孢子， 利用潮汐驱散那些孢子，就像他们世世代代的祖先所做的那样，并逐渐从水生生活过渡到陆生生活。

What if we also told you that other types of fungi can absorb oil spills, control insects' brains and that fungi in general are essential to all terrestrial life on Earth?

如果我们还告诉您其他类型的真菌可以吸收漏油、控制昆虫的大脑以及一般而言真菌对地球上所​​有陆地生命都必不可少，您会怎样？
