Summary

Evolution loves to plagiarize. You might be surprised at just how useful it can be for an organism to copy the signals, sights, sounds, and smells of others. Mimicry is all about making use of miscommunication. In this episode we’ll discuss the astounding diversity of modern mimics, the rare examples of fossil mimics, and the complex and confusing evolution patterns of mimicry. In the news: Cambrian bryozoans, early tusks, hermit worms, and parthenogenetic condors.

0:00.0	You're listening to the Common Descent Podcast.
0:19.0	Hello, David. Hello, Will. And hello, listeners.
0:22.0	Welcome to episode 126 of the Common Descent Podcast.
0:25.8	Today we are discussing mimicry.
0:27.7	Oh, it's going to be a good one.
0:29.0	I think so, too.
0:30.0	Mimicry is a feature that we oft see in many organisms where one organism takes on the traits of another to benefit from the original purpose
0:42.4	of those traits.
0:43.5	Right.
0:43.9	I am copying this thing because it behooves me to do so.
0:47.4	Yes.
0:48.0	So this is different than we just ended up looking similar for similar reasons.
0:52.6	Right.
0:52.9	That's convergence.
0:53.8	Mm-hmm. Episode 70. Which we will discuss
0:56.1	in this episode, the ins and outs of that, but this is, I am looking like someone else or
1:01.0	acting or smelling like someone else to trick someone. Right. There's deceit in mimicry,
1:08.6	basically in all cases. So we will go through exactly what that means
1:13.6	and the variety of it. And then what types of mimicry do we see in the fossil record and how might
1:20.3	it evolve in the just ridiculously diverse list of examples? Very cool. This is going to be an
1:26.9	episode full of neat examples of
1:29.4	mimicry. Oh yeah. I'm sure. It gets so weird and crazy. It's going to be a lot of fun to dive into some of
