The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

They can produce a bunch of different types of spores, sexual and asexual, a bunch of different fruiting bodies that can survive various disturbances.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

So one way is through this sexual reproduction, they are able... Okay, so one thing that's really cool about Basidiomycete fungi is that they literally, instead of... We are all diploid.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

We have our genes from our mom and our dad, and they combine...

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

And then we have two copies in our cells.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

What they do is they separate them.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

And so they're literally separated by either a clamp connection or a septation where the two nuclei are separate.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

and they can have separate genes in them, and they can express different genes in these different nuclei.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

They only join really briefly, like basically at the moment of meiosis.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

I don't know why we're looking in the cosmos for aliens.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

We have aliens right here on Earth is what I'm hearing.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

Yeah, fungi are really cool.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

I mean, they really are really interesting.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

And then the last thing that also is my favorite is they actually were able to co-opt these genes from bacteria.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

So bacteria have really amazing abilities to...

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

like all sorts of metabolic abilities.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

And they are able to do horizontal gene transfer where they transfer genes from one organism to another.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

So like for us, we have vertical transmission.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

Like a mom gives birth to a baby.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

That's the only way you can transmit genes.

The Last Show with David Cooper
Fire-loving, Charcoal-eating Fungi

But for bacteria, it's like, imagine you could share genes with your friends or you could share genes with other people in the room around you.
