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?

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.

They had chemical batteries that would be connected to statues of Zeus that would shock when touched. They had primitive steam engines that would spin up when boiling water was heated inside them. They had the archimedes screw. Complex machines for milling,stamping, grinding. If someone had known of all these pieces and thought to combine these technologies to actually do work then you have an industrial revolution.

There's a fair amount of randomness to it as well. You need all these important pieces, but you need them to come together in the right way, the right time, and in the right place. The ancient Greeks had all they needed to jumpstart the industrial revolution 3,000 years ago, but the pieces were locked away as religious displays and secret knowledge in mystery cults.

Genetic disorders can happen both from random mutation that happens just to one person, and inherited mutation passed down from the original mutated ancestor to descendents. An inheritable mutation must happen in an egg or sperm originally to be passed down, such as sicle cell anemia.

Random mutations otherwise, such as bone cancer in example, are not passed down. Random mutations appear the same a lot of the time because our genes can be broken in some ways more easily that others that cause rare diseases.

Our genome is a patchwork thing from several different human and human ancestor lines and it's amazing it all works together as well as it does.
