But if you take samples and bring them back here and start to culture them,

like we did on top of a building, leaving them, you know, you will see the second generation of this organism, they are starting to switch on and off again.

So they are extremely adaptable, extremely rugged, and that's why they are still here.

And probably that's why we're here, because life founds ways.

Well, it will shut down those that cannot survive.

Obviously, you know, this is a statement that's kept an obvious right there, but it's also the survival of the fittest.

And this is what evolution is, right?

So they are here because they were the most adaptable.

And so evolution is going to show the path of the fittest.

The one that cannot resist, they might have a good time for a little while, but then, you know, we've seen this at much different scale and with complex life.

Not so long ago, 100,000 years ago, Neanderthal.

was side by side by Homo sapiens.

But Neanderthal was completely adapted to a cold earth, to a glacial earth of the end of the Pleistocene.

And when conditions change, it couldn't last.

No, no, no, no.

No, no.

Some shady stuff that happened.

Shady stuff happened.

They met.

They bred together.
