Summary

Nearly all animals have some form of nervous system, and this system is often monitored and regulated by a brain. We humans are particularly proud of our enormous brains, but these organs come in all shapes and sizes across the animal kingdom, past and present. In this episode, we discuss brain diversity, the sometimes roundabout ways we explore brains in the fossil record, and what we’ve come to learn about the evolution of brains. In the news: turtle embryo, frog-legged leaf beetle, early lizard cousin, and tyrannosaur brains.

0:47.6	discuss the organ the brain as in what is it you know what a brain? What makes it a brain?
0:55.6	What is our brain?
0:59.5	Because our brain is a very complex thing that we have studied immensely.
1:01.5	We as a species are very proud of it.
1:02.0	Oh, yes.
1:03.4	We think it's pretty great. So we're going to go through a semi-detailed, not actually detailed, since it's the brain.
1:10.2	Semi-detailed walkthrough of our mind, how it compares to other brains,
1:16.1	and then we'll talk a little bit about how do we study brains of the past,
1:20.1	and what do we think might be some of the evolutionary history of brains?
1:25.6	Yeah, this is one of a few episodes that we've done on body parts. Yeah.
