One other exhibit in the hall was for Evolutionary Genealogy, an excellent site run by Len Eisenberg of Ashland, Oregon. I was in Ashland a while back and got a tour of the geology walk he installed there, which is phenomenal — look it up if you’re ever in town.
He’s selling posters and t-shirts to support his work in evolution education. One of the hooks he uses to get people interested is to talk about relationships in the great big family of life on earth, and he estimates the number of generations that separate us from any organism you might be interested in. He’s got nice shirts that show how closely related you are to that animal; wouldn’t you know Jerry Coyne got in there early and snatched up the kitty-cat shirt? I got a dragonfly, because invertebrates are always much cooler.
