Oh, I just realized what panspermia means.

噢，我好像发现胚种论很污。

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

" 我们证明了这些物体携带能够产生生命的物质（被称为" 有生源说" ）的可能性。" 张说。

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

胚种论声称生命的起源不在地球，在地球之外。

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

下，你千万别以为人类是古代时外星生命带到地球上的，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.

但个更有趣且更有可信度的理论是泛种论。

Many researchers consider this hypothesis, called panspermia, unlikely.

研究人员认为这种称为生精论的假设不太可能。

This is the thing about panspermia, right?

这就是关于泛种论的事情，对吧？

You mean, like, in that directed panspermia?

- 你是说像定向泛种论那样？

So, it's also the idea of panspermia.

所以，这也是泛种论的想法。

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

我实际上——指导泛种论或播种进化的某个方面。

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

但对于些科学家来说， 生精论假说仍然有希望。

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

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

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生精论， 并且生命可以很容易地散布在整个宇宙中， 那将从根本上改变我们地球人看待自己的方式。

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， 生精论的概念在定程度上是由 1883 年喀拉喀托岛上座火山的巨大喷发引发的。

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 博士在十年前的次会议上以提出地球生命起源的生源论模型而闻名， 但今天他持怀疑态度。

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时代所认为的要古老得，因此无需借助泛种论来解释地球上生命的起源。

" 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.

“如果生精论是可能的，我们的生命可能起源于火星，”东京药学与生命科学大学的天体生物学家、这项新研究的主要作者 Akihiko Yamagishi 说。

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，生命由太空岩石带到地球的想法，也就是人们所称的“胚种论” … … 根本没有任何证据证明它曾经发生过，而且它也不能真正解释生命的起源。
