And, two is that being centrally located, it is at best a somewhat isolated sampling of the Olmec facial characteristics. One has to consider that the faces are similar to those of the eastern world. This would lead one to group these people with the Mongoloid races of Chinese, Japanese, Malaysians, Mongolians, Siberians, Eskimos, and American Indians. The eastern route to the sea is a possible avenue traveled by the early Jaredite expedition until they reached the Pacific if they came that way. One must also consider that the populous was derived from a small original group which would entail much more inbreeding than that which would have occurred in comparison to the other descendants of Noah left behind from whom the rest of the world is made up of.
Scholars divide the 'Mesoamerian' civilization development into three periods.
Their assumption is that the evolution of the people is one homogeneous group of people evolving from one period to another. They assume that the Olmec group grew into the later Mayan people. Any synthesis of Mayan prehistory at this point is merely speculation. The truth from scripture, is that the Olmec or Jaredite group where only as closely related to the later 'Mayan' group as the first few generations from Noah would allow. They were a different people and evolved separate and apart from the Egyptian and Jerusalem back grounds of the Mayan who themselves where hundreds of year removed from even that middle eastern origin by the time they came to the land of Central America.
