When evolutionary biologist Richard Dawkins' daughter was six years old, he told her that flowers are not here for beauty, not here for the bees, but instead merely to copy their own DNA. Sigh, what a Dad. So is Richard Dawkins always so gloomy and reductionist about the world? Well yes, but he would say that his vision of the world is anything but gloomy, he even calls it romantic. In this conversation from the 92nd St Y, Robert challenges Dawkins on this and a number of other sticky spots on the topic of biological evolution.

After we released our show about Stochasticity, we received a lot of comments about the idea humans can be just as predictable as coins. In that show, Jonah Lehrer was telling us about a study on the 82-83 76ers, and he was saying that even when a basketball player is supposedly hot – really on a streak – he is no more likely to make his next shot that any other time. Basketball players are slaves to their averages. Well, it turns out this isn't the whole story.

Stochasticity (a wonderfully slippery and smarty-pants word for randomness), may be at the very foundation of our lives. To understand how big a role it plays, we look at chance and patterns in sports, lottery tickets, and even the cells in our own body.
