I just returned from the Yucatan Peninsula in Mexico.  I learned that the Mayan
Indians had a practice of squeezing their babies' heads between two flat boards
bound together to force the head into the familiar pointed and "angled-back"
form which they found beautiful.  But I don't understand how this has apparently
resulted in the DNA of the contemporary Mayan Indian typically born with
similarly shaped heads . . . unless the DNA of Mayan Indians has been somehow
modified by the practice many years ago.  I reviewed the archive ID:
982014507.Ge and it doesn't really address this question.
