Evolang ended with a presentation by Terrence Deacon that gave everybody plenty to contemplate while they wait for volcanic ash to clear from the Atlantic and northern European skies. Deacon is a neurologist and anthropologist along with teaching a course on evolution at the University of California at Berkeley. His presentation covered all these areas and covered them in original, creative ways that forced everybody to pay close, persistent attention. I’m not sure how much the tired, ready-to-go-home audience was able to take out of the presentation, but I’m hoping they came away with at least an appreciation that they need to learn more. In the opinon of this blog, Deacon gave the most important presentation of the conference, and that’s saying something after Christiansen’s great contribution yesterday morning.
