Document Summary
Plant domestication may be defined as growing a plant and thereby, consciously or unconsciously, causing it to change genetically from its wild ancestor in ways of making it more useful to human consumers. Many crops like almonds were originally poisonous and bitter tasting. Seeds from gathered fruits pitted on the found at camp reproduced. Some fruit rotted on the ground and the seeds germinated. Grains dropped on the ground on the way back to camp reproduced. Seed and fruits dropped as part of human faces reproduced. Some were edible but had other characteristics making them unsuitable for domestication (easily scattering seeds, seed ripening not taking place uniformly) Some criterion had to do with the characteristics and qualities from consumptive use: Cultivated peas 10 times bigger than wild peas. Cultivated apples are 3 inches in diameter, wild are 1. Wild corn barley hand an inch we can get them to more than a foot.
