When we invented Society
Around 10 000 BCE the humans came to know that, given enough time, seeds, earth and water could produce food.
Most probably they started by burying seeds in fertile fields without paying too much care or attention. After a few months they would come around the same place and the expected crop would have appeared. This almost magical experience must have convinced them to settle quite quickly. A fairly stable and predictable source of food is one of the first things you pray for when you are on your own.
So at first, this new source offered the advantage of supplementing the hunting and collection; they didn’t have to go around for food so often. But if they were to replace the old ways almost entirely and for the whole clan, there was a lot of work to do in the fields. They had to accept (or rather they succeeded in) becoming sedentary and settle.
People had to learn and become experienced, the methods had to be improved: ploughing, planting, eventual watering and harvesting.
Some were better at doing some things rather than others, so they started to concentrate on what they could do best.
Probably that availability of food allowed them to lure and capture animals, either to eat them or to condition them to work in the fields.
Suddenly, sedentarism, the specialisation of tasks and the domestication of food sources became the main traits of humans.
With these favourable changes came also the first human chronic issues: the proximity to animals brought them illnesses, the specialisation and organization of tasks brought organised work, the abundance of carbohydrates brought tooth decay. Together with all its consequences, good and bad, Society was born.
