Earth had just managed to evolve multicellular life.

上刚出现了多细胞生物。

And they can do it because they're multicellular, which is a rarity in the microbial world.

它们之所以能够做到这一点，是因为它们是多细胞的，这在微生物世界中很少见。

Several years ago, Albani and his team discovered it held the oldest fossils know of multicellular animals.

几年前，阿尔巴尼和他的研究小组发现这里保存着已知的最古老的多细胞动物化石。

The tentacled Archaean uses proteins common to multicellular organisms and might lend insight into how the latter evolved.

这种有触角的太古代微生物使多细胞生物共有的蛋白质，这可能有助于我们了解后者进化的方式。

Some people have even suggested that there could be multicellular life, such as fish-like creatures down there.

一些人甚至推测这些寒冷星上还可能有多细胞生命，比如说像鱼一样的生物。

Ultimately, it gives rise to a sophisticated system of cooperation that's somewhat like a multicellular organism in itself.

最终形成一个复杂、精致的合作系统，有些类似于多细胞生物。

By 800 million years from now, every green thing on Earth is dried up, and all multicellular life with them.

八亿年后，上不有何绿色植物，以及何多细胞生物苟活。

At some point, these cells began to form small groups or communities, which lead to multicellular life, and finally, to you.

渐渐，这些细胞开始形成小组或群体，导致了多细胞生命，最终形成了你。

Multicellular organisms, then larger animals, could now evolve thanks to this new element, essential for keeping these increasingly complex biological machines running.

多亏了这个新元素，多细胞生物和更大的动物才得以进化，这个元素对维持这些日益复杂的生物机器运转至关重要。

But then, scientists think an increase in oxygen allowed multicellular lifeforms to extract more energy from their food and perform more complex functions.

但科学家认为，后来氧气的增加让多细胞的生物得以从食物中取得更多能量，进行更复杂的功能。

Even further down at 3,600 meters is the deepest point that a multicellular organism has been found alive — this freaky looking worm.

再往下3600米深处，是目前发现有多细胞生物生存的最深处——这种看起来怪怪的蠕虫。

And this isn't just the case for humans — it's true of every animal, plant, and fungus, and nearly every multicellular organism on Earth.

而且这不仅仅是人类的情况——每种动物、植物和真菌，以及几乎所有上每个多细胞的生物体都是如此。

There are so many different kinds of seaweed, there's unbelievable genetic diversity in seaweed, and they're very ancient; they were some of the first multicellular organisms ever to evolve.

海洋中有很多不同种类的海藻，存在着不可思议的遗传多样性，而且它们非常古老；它们属于最先进化的一部分多细胞生物。

With oxygen's role in releasing energy, enabling the release of lots of energy through chemical reaction, it's more useful for animals, and probably led to the evolution of multicellular organisms.

由于氧气在释放能量方面的作，使其能够通过化学反应释放大量的能量，所以它对动物更有，可能还导致了多细胞生物的进化。
