And then that sacrifice allows the younger members of this community to hopefully survive a little bit more until maybe better times come along.

So that was a crazy, not crazy, it wasn't crazy, it was a really good project, but it was a surprise.

I mean, everything I'm going to tell you is a surprise.

So yeah, Amea was this postdoc that found that.

And of course, again, and I think this is what you're alluding to, is that we know there are all kinds of programmed cell death processes in human cells.

So for example, when you're an embryo, your feet and your toes are webbed.

And then the cells that are in between your toes and your fingers, those cells, as one example, those cells die and you get your digits.

That's a programmed cell death process that gives you, for example, your fingers and toes.

There's others.

And again...

Programmed cell death was thought to be in eukaryotes, right?

So we don't really know, in this case, we don't actually know if this quorum sensing trait is actually programmed cell death.

It sure smacks of it.

For quorum sensing, we know these bacteria are carrying out collective behaviors.

We know that.

may have found that these cells do die.

They die in this regional way.

Quorum sensing controls it.

We hinted in the discussion of this paper that perhaps, just like quorum sensing was the original collective behavior, perhaps bacteria also have programmed cell death mechanisms

as do eukaryotes.
