Absolutely nothing disparaging meant.
Why are people of Mexican decent short in stature?
Because several hundred years ago:
** they did not inter-breed with tall cultures
** Being Tall wasnt a particularly attractive trait and therefore was not passed on.
** There was no cultural or evolutionary advantage to being tall in Mexico.
** There were advantages to being short in stature in mexico. You blend in with the rest of the population. You dont need larger animals to transport you. You dont need as much food. Easier to farm lands. Basket wont be invented for a few hundred years.
