Document Summary
Enough calories that your effort in gathering them is worth eating them. The early farmers were not conscious of how to properly farm, accidentally picked the better plants. 200,000 plants species but only a small fraction are good and edible. Eurasia had 33 of the 56 prized large-seeded grass species: animals. The calorie trade-off is not efficient enough for carnivores. Respond to a dominance hierarchy: the big five. Same latitude, same climate, same seasons, same day-light schedule. The trade routes can carry plants that will have a high chance in living in both the east and west because they had similar living environments. North-south had the desert, ocean, rivers, saharan desert, difficult for technologies, plants and animals to travel north to south. Faster spread of food production . 7/ year in europe vs . 2 to . 5 in americas. Climates more centrally similar (north and south vary vastly) Farming societies had more people because you could make more food to support people.
