[Aztlan] African Olmecs

[Sam Edgerton]

One bit of circumstantial evidence that there was no consequential 
"peopling of the Americas" after the Beringian crossing until the arrival 
of Columbus is that neither of our two continents was likewise ever visited 
by the terrible plagues that swept over the conjoined Eurasian and African 
continents from biblical times through the Middle Ages. In fact native 
America was suddenly and horribly vulnerable to a flock of diseases which 
the European invaders brought over for the first time. While the Europeans 
and even their later imported African slaves were partially immune due to 
ancient exposure, the indigenous Indian population had no such genetic 
defense, and were almost immediately ravaged by what may have spread from a 
single infected sailor who deposited his germs on the beach of  "San 
Salvador" on October 12, 1492.
