"And only people with shovel shaped incisors can properly speak Chinese."

All Chinese do not have the 'shovel-shaped' (Sindont) teeth (Christy Turner). The North Asians are descended from South East Asians (Oppenheimer) who have predominately Sundadont shaped teeth. The North Asians have the Sindont teeth, peculiar eye-lid, flatter faces and lighter skin

BTW, Kennewick Man has Sundadont shaped teeth like South East Asians.

So things can actually be a bit more complicated than we believe when viewing the peopling of the Americas.

For example, if the Celts arose from areas within present-day China, than some European-appearing North American 10,000 y/o remains (eg, Kennewick man) may have STILL come from Asia. What do you think?
