Wow, this was an awesome lecture. Admittedly, the introduction in lecture 1 was so long that I almost gave up. Evolution stuff was fine but I bet that EVERYBODY in the room could spell out that history without notes... but once that was done with... excellent. I like the concept of culture as physical portion of ourselves, since we are capable of, and often change our culture, with all that entails, with the same ease we change our hairstyles. Congratulation. Great job on the lecture.
