" We show the possibility of panspermia carried by these objects, " Zhang said.

" 证明了这些物体携带能够产的物质（被称为" 有源说" ）的可能性。" 张说。

The theory of panspermia states that life didn't start on Earth, but instead was brought here.

胚种论声称的起源不在地球，在地球之外。

Oh, I just realized what panspermia means.

噢，好像发现胚种论很污。

Now hold on, before you start to think that ancient aliens did it, panspermia actually refers to the transference of bacteria.

等一下，你千万别以为人类是古代时外星带到地球上的，因为胚种论实际上是菌转移学说的引用。

But a more interesting theory, and one which has more credibility, is that of panspermia.

但一个更有趣且更有可信度的理论是泛种论。

I've actually- - Directed panspermia or seeding some aspect of the evolution.

实际上——指导泛种论或播种进化的某个方面。

So, it's also the idea of panspermia.

所以，这也是泛种论的想法。

But the idea that life was delivered to Earth on space rocks, which goes by the awesome name panspermia… well there's just no proof it ever happened, and it doesn't really explain the origin of life anyway.

但是，由太空岩石带到地球的想法，也就是人所称的“胚种论” … … 根本没有任何证据证明它曾经发过，而且它也不能真正解的起源。

" Our life might have originated in Mars if panspermia is possible, " says Akihiko Yamagishi, an astrobiologist at the Tokyo University of Pharmacy and Life Sciences and the lead author of the new study.

“如果精论是可能的，的可能起源于火星，”东京药学与科学大学的天体物学家、这项新研究的主要作者 Akihiko Yamagishi 说。

Earth is now known to be vastly older than was believed in Darwin's time, so panspermia is not needed to explain the origin of life on the planet.

如今已知地球的年龄远比达尔文时代所认为的要古老得多，因此无需借助泛种论来解地球上的起源。

But for some scientists, the panspermia hypothesis still holds promise.

但对于一些科学家来说， 精论假说仍然有希望。

This is the thing about panspermia, right?

这就是关于泛种论的事情，对吧？

Many researchers consider this hypothesis, called panspermia, unlikely.

许多研究人员认为这种称为精论的假设不太可能。

You mean, like, in that directed panspermia?

- 你是说像定向泛种论那样？

The concept of panspermia was kicked off, in part, by the humongous eruption of a volcano on the island of Krakatoa in 1883, says Dr. Melosh.

Melosh 博士说， 精论的概念在一定程度上是由 1883 年喀拉喀托岛上一座火山的巨大喷发引发的。

So that's the generalization of what the famous astronomer Fred Hoyle called, I know this is a PG-13, it's called panspermia.

这就是著名天文学家弗雷德·霍伊尔所称的——知道这是PG-13级别的——它被称为“泛种论”。

Although he famously entertained the panspermia model for the origin of life on Earth at a conference a decade ago, today Dr. Benner is dubious.

尽管 Benner 博士在十年前的一次会议上以提出地球起源的源论模型而闻名， 但今天他持怀疑态度。

But if panspermia is indeed possible, and life can be readily dispersed throughout the cosmos, it would fundamentally change how we earthlings see ourselves.

但是，如果真的有可能出现精论， 并且可以很容易地散布在整个宇宙中， 那将从根本上改变地球人看待自己的方式。
