So it is a mechanism that it can happen different ways, but often the places that you see it happening are the places where DNA is likely to get damaged.

And so it is often a repair mechanism.

And again, it's not limited to asexual species.

It can happen in one of your cells when your cell is copying.

And again, we all have two copies of all of our genes.

So sometimes one of them gets damaged, one of them, the DNA just breaks.

Maybe it's when it's getting copied, maybe in another scenario.

But the way that the cellular machinery can repair this, if a piece of the DNA is missing, is to exactly, as you said, use the other copy as a blueprint to fill in the gap.

Almost.

So it means that except for gene conversion and mutations, they are copies of one original Amazon Mali.

So, yeah, it can be really difficult to talk about evolution without veering into using language that suggests some sort of consciousness behind it that knows what it's doing.

And so often, even evolutionary biologists resort to using this kind of language.

And that's fine, as long as you remember that evolution

at the end of the day, it's really a random process going on.

And so in this case, the gene conversion is doing the same thing.

It happens in random places.

And maybe it happens in a place that is doing something helpful.

And maybe it happens in a place that's doing something not helpful.

Most of the time, it's going to be happening in a place that does something neutral.

It's not good.
