Celebrate Darwin Day!

Today is the 201st birthday of Charles Darwin. As both a celebration of his life and ideas, and as a means of scientific public outreach, I gave a talk last night entitled:


I got the first part of the title from the question and answer session after a presentation on creationism that P.Z. Myers gave in Manitoba. One audience member charged P.Z. with the task of explaining how evolution red in tooth and claw could have resulted in a "molecules to morality" transformation. P.Z. rather tactfully responded:
"...he's demanding a bit much for a short answer. Forget the molecules part, since they don't exhibit morality; all you need to know is that a population of apes found it advantageous to regulate their activity to promote cooperation, and voila, here we are, apes who say that rape is a bad thing."
After seeing the same inane question pop up again during a debate between Frank Turek and Christopher Hitchens (i.e. "How do you get morals from an carbon atom?"), I felt obligated to take this opportunity to give other materialists an answer.

My presentation gave a brief overview of some of the ways we understand how altruistic behavior can evolve in natural systems, and rebuts the idea that morality can have only been a gift from a higher power and is therefore proof of that higher power's existence. You can view the slides below:

I was pleasantly surprised that my presentation was standing room only. I wish I had actually counted, but the room holds ~18 chairs so there were probably around 25 people that showed up. I wish I had been a bit more entertaining (everyone loves a good sight gag) and presented less but did it more clearly. Some of the details about kin selection and reciprocal altruism could have been cut back, and I wish I had done a better job explaining the examples of altruistic behaviors observed in animals. Still, I think it was a great turn out and hopefully the people there went home a little more informed than they were when they came.

I'm also having a Darwin Day party tonight at my house, so call me if you're in the Kent area with nothing to do. Since I'm a huge nerd, I'm making it a theme party: come dressed as your favorite adaptation! I blatantly ripped that idea off from another party, but it is so good I couldn't resist. My amazing fiance also made me some delicious "electrophoresis" cookies, which I will definitely have to post pictures of later. Happy Darwin Day everybody!

  1. I love the idea of the talk. One thing that some people forget is that relatedness underestimates the genetic incentives for altruism. All humans share the overwhelming majority of genes. If you save the life of a stranger, most of the genes you will be saving will be your own.

    I hope you had a great party.

  2. Hey Dan, great talk! And I have to say, this is a snappy blag. I'll definitely be watching it -- I'll add it to a list if I can find some way of organising feeds that doesn't involve going insane.
