I think Greg's 'biologists' are a special subset of biologists. As I see it CP Snow was right about the two cultures. But within science there are also two cultures, one of whom speaks mathematics and the other that speaks organic chemistry. Speaker of organic chemistry share a view that enough lab work and enough data will answer all the questions. They don't need no silly equations.
In our field the folks who speak mathematics tend to view the lab rats as glorified techs. This is certain not right but it is there and leads to a certain amount of mutual disdain.
This kind of mutual disdain is apparently just not there in physics between the theoretical and experimental physics people. I wish evolutionary biology were more like physics.
Edit: Q&A is now closed. Thanks to everyone for participating, and thanks very much to Harpending and Cochran for their responses.
In response to Kaj's review, Henry Harpending and Gregory Cochran, the authors of the The 10,000 Year Explosion, have agreed to a Q&A session with the Less Wrong community.
If you have any questions for either Harpending or Cochran, please reply to this post with a question addressed to one or both of them. Material for questions might be derived from their blog for the book which includes stories about hunting animals in Africa with an eye towards evolutionary implications (which rose to Jennifer's attention based on Steve Sailer's prior attention).
Please do not kibitz in this Q&A... instead go to the kibitzing area to talk about the Q&A session itself. Eventually, this post will be edited to note that the process has been closed, at which time there should be no new questions.
