That's not even close to the case here.
The ep. shows and states that the Native American's were mentally challenged but because they respected nature, the aliens "blessed" them with average intelligence. That's a very racist picture they paint because it's calling Native American's savages and incapable of evolving mentally as well as every other race and culture on Earth.
I have to disagree with that interpretation.
The ep seems to discuss early Cro-Magnon man
on the eastern hemisphere of the planet that have yet to develop a culture, not a mentally deficient race. Think many thousands of years ago
, like when the reimagined Battlestar
Galactica first landed on "our" earth.
43,000 years ago, on our first visit to your world, we met a small group of nomadic hunters
. They had no spoken language, no culture, except the use of fire and stone
weapons. But they did
have a respect for the land and for other living creatures that impressed us deeply. We decided to give them an inheritance, a genetic bonding
so they might thrive and protect your world
. On subsequent visits, we found that our genetic gift brought about
a spirit of curiosity and adventure. It impelled them to migrate away from the cold climate to a new, unpeopled land.
It took them almost a thousand generations
to cross your planet. Hundreds of thousands of them flourished in their new land. Their civilization had a profound influence on others of your species.
But then, new people came with weapons and disease. The Inheritors who survived scattered. Many sought refuge in other societies. Twelve generations ago, when we returned, we found no sign of their existence.
