Summary

Glowing organisms might seem like something out of science fiction, but not only do they exist here on Earth, they are incredibly common. Some species glow when exposed to certain kinds of light, and others produce their very own light in the darkest habitats on the planet. This episode, we explore glowing life: how they do it, what they use it for, and what we can tell about how this remarkable ability came to be. In the news: painted turtles, dinosaur herbivores, human brains, and insect ears.

0:00.0	You're listening to the Common Descent podcast.
0:19.0	Hello, David.
0:20.2	Hello, Will.
0:21.2	And hello listeners.
0:22.7	Welcome to episode 157 of the Common Descent podcast.
0:27.6	Today we are discussing bioluminescence and biofluorescence.
0:31.8	This should be illuminating.
0:33.7	Yes.
0:34.8	We're going to talk about things that glow.
0:37.0	Glowing creatures. Creators, creatures, critters, organisms, actually. Yeah, all sorts of life. So these are two
0:43.2	different ways that life can glow. And they are distinctly different, even though at a glance, literally,
0:51.3	they might look similar, but they are different, but they have a myriad
0:57.0	of uses and are found just across life. So we'll discuss what they are, you know, what does it
1:03.8	mean to luminous or flores, what organisms do it and what do they use it for, and then a little bit about what do we know about how things started to glow?
1:16.1	Yeah, the evolutionary insights into this phenomenon.
1:19.1	Absolutely.
1:20.3	This is a massive topic where we could have zoomed in on pretty much any group of life.
1:25.8	Sure.
1:26.3	And we've chosen not to.
1:27.3	Yep. Like, we could have just picked a group of life and go. And we've chosen not to. Yep.
1:27.7	Like, we could have just picked a group of life and go, all right, we will only discuss it
1:31.0	within this and that would have given us enough.
