You can't.
Correct.
In my view.
Yes.
And not just my view.
That's a fact.
But that is also my life's work.
And so I do think that's how they work.
accomplish so many of the good and the bad things, and we know that for a fact.
So that's quorum sensing.
And so the way it works is that bacteria, they consume nutrients from their environment, they double their size, they double all their components that are in them, and they divide in half.
And so one cell becomes two, becomes four, becomes eight, so they just divide asexually.
And then what they also do is that they make and release more molecules that you can kind of think of like hormones, right?
And so as the bacteria are growing in number, you know, more cells, since each of the bacteria is making a share of these molecules and releasing them into the environment, the amount of these molecules around the cells increases in step with the number of cells present, right?
More cells, more of the molecules.
And when the molecules hit a particular amount of
they get above the threshold that the bacteria can detect.
And when the bacteria detect the molecules, they infer from that detection event that they must have neighbors around.
And so in unison, all of the bacteria change their gene expression, which allows them to make new proteins that change their behaviors, and they begin to, in synchrony, carry out these group behaviors.
So they don't have a clue.
