3 stars The wolf at history's door | Razib Khan’s Unsupervised Learning This eruption of warrior ferocity five thousand years ago was triggered by an economic revolution that swept across Eurasia, the advent of an unbeatable new cultural toolkit that finally harnessed the full productive potential of the cattle, sheep and goats that had long been viewed as simply mobile meat lockers in agricultural societies. Though these animals had already been domesticated by 8500 BC, it took millennia to perfect milk, cheese and wool production, and the harnessing of oxen as beasts of burden. North of the Black Sea, this revolution arrived around 3500 BC, as small groups of farmers huddling on river banks shifted from a mixed agro-pastoralist production system eking out a living cultivating wheat in an unforgivingly short growing season, to one of pure pastoral nomadism that turned over the vast grasslands around them to massive herds of animals.
