Document Summary
Bio220 lecture 8: ecology of ancient and modern food production. Quaternary period: dramatic changes of era, glacial periods and interglacial periods. Agriculture emerged during holocene epoch (interglacial period) Having a primitive diet can be unreliable. Good fruits appearance selection disperse of seed fruits, seeds, and tubers that are less defended in plants and packed with nutrition seeds and tubers (energy storage organs) Grasses (wheat, rice, maize, barley, non-shattering seed heads, amylase evolution) legumes (beans, lentils, chick peas) fruits (tomatoes, squash) independent origins stored seeds, plants, cultivate. Ancient technical innovations fishing by net irrigation (water) tunnels. Domestication of cattle, sheep, poultry (or lactose tolerance) Use of plow crop rotation, draft animals (working animal) change from scavenging to the rise of cities. Irrigation brought water, solve the drought problem. Rothamsted john bennet lawes chemical fertilizers. Soil amendments exhausted soil: repeatedly use of soil, less transfer of nutrients from the soil to the crop over time.
