Below is a video of the talk I gave at the Harvard Museum of Natural History nine days ago, “Why evolution is true and why many people still don’t believe it.” The original website of the “Evolution Matters” lecture series is here, where you can see other talks in the series by Jack Szostak, Randolph Nesse, and Iain Couzin.

The introduction is by my old friend Andrew Berry, a lecturer and advisor at Harvard. What he says is true, except that my draft number was low—#3—instead of high, a number that was a recipe for going to Vietnam in those days. The Harvard folks are trying to add the Q&A to this video, and the sound is a bit weak at the very beginning of my spiel, but improves about a minute in.
