Reply to comment by xydanil in How are there more genetic differences between two of us than between us and Neanderthals? by bookposting5

I'm thinking that the viable variations in early Sapiens, Sapiens/ Sapiens, Neanderthalis were few, and so the differences between our population today and then would be small as there are few working combinations in the genome "lock" as it were. Was the study done between hybridised Sapiens, Sapiens populations vs Sapiens, Neanderthalis, or non hybridised vs. Sapiens, Neanderthalis?

I've dealt with (annoying, but not dangerous) low blood pressure my whole life, and never once has a medical professional ever mentioned flexing my core as a way to combat occasional dizziness. I'm weirdly excited to try it out!

Europe was a boiling cauldron of death, plague, and blood since the fall of the Roman Empire.

Then it met China again.

Then Europe was a boiling cauldron of death, plague, blood and innovation as they used the cross pollination of ideas to find more efficient ways of death, plague, blood. WWII ended this...

for now.

Edit: Russia has unpaused the game.

They did not have animals in north America suitable for domestication to magnify their work potential. They did not have farming technology on an industrial scale, and they didn't have the social structure suitable for long term growth in most cultures. There were a few exceptions in prehistory but they did not survive to contact with Europeans. The Aztecs being the only empire that did exist then. There were a long string of prehistoric empires in the Americas but for the most part they were separated by time and distance from each other.

Edit: the Incas also had contact with Europeans.
