Pretty odd, huh? This was mentioned on a BBC documentary on genetics a couple of weeks ago. When I mentioned this later on I had several tables of men in a gay pub all holding out their hands and comparing finger lengths. Judging by this rather amateur practical test there didn't appear to be any basis to this theory at all. Ho-hum. And since no-on else has mentioned it - Wolfe's essay "The Best Introduction to the Mountains" is up for the British Science Fiction Association's Non-Fiction Award --
