So... people who part their hair in the middle are ambidextrous? ;^) Dogs and rodents sometimes have funny little whorls. I just looked over at Skrogg and asked if I could search her hair and she gave me one of "those looks"... being a long-haired cat, any curliness would be hard to notice anyway. I've read something about the gene which determines stripes during development, but not about whorliness. Now I'm curious. Fruit fly legs are something else again. Those aren't really hairs, if hairs are something only mammals have. Carolly
