Reddit reviews Ultrasociety: How 10,000 Years of War Made Humans the Greatest Cooperators on Earth

There is an argument using evolutionary theory that agriculture was only adopted to increase group fitness at the cost of indivual fitness.

Lots of civilisation diseases started with the adoption of agriculture.

So there is the argument that agriculture made civilisation possible but at the cost of pure indivual strength and physical prowess.

There is lots of evidence that early agricultural societies had less than healthy members compared to hunter gatherers.

When you think about it, the indivual skills of a warrior in a large army is less important than pure numbers, most armies in the past were farmers called to war once a year, and yet the prevailed most of the time against nomad societies whos way of life made them formidable indivual warriors like the steppe people, just by numbers alone.

Edit:

If someone is interested where these theories come from, I recommend these books:
