Here's a link to a picture (won't let me right-click). Yes, I do indeed have "shovel teeth", but that's probably thanks to the Mexican Indian in me. The info I read said it's an "Asian" or "Indian" trait. So, it's fair to say that if someone has shovel teeth, they are not pure Northern European?

That's my understanding, although I haven't read about this for a number of years.
