Touch your tongue to the back of your two upper top front teeth. Are they wedge shaped like your bottom front teeth or are they kind of shaped like a shovel, a little scooped in with a bump up at the gum? If they are shovel shaped you may have a Native American ancestor. I don't remember if Asians also have this trait. Maybe someone with an Asian ancestor can tell us, but it is a dominant trait passed down through Native Americans. I have the shovel shape, but I already knew I had a distant Paiute ancestor even though I don't look like it.

What about you, wedge or shovel?

I forgot to add that Europeans and Africans do not have the shovel shape, they have the wedge.
