There's quite a bit in this Radiolab story, but the central question is where does morality come from? Is morality taught or is it innate? For our purposes, this will be a memorable example of evolutionary psychology.

Here's the link to the story: http://www.radiolab.org/story/91508-morality/

I wanted to reiterate some of the things that I was discussing in class about class notes. Specifically, with this story, there is quite a bit of extraneous stuff that can be ignored. The storytelling is rich, complex, surprising, and memorable. That's why I use it. Michael Sandel, the famous philosophy professor from Harvard uses the trolley experiment has used and presumably still does use it in his classes as well. Your notes, however, should be shorter rather than longer, but include lots of space to add things later on.
