BIOB38H3 Lecture 3: Origins of agriculture
Document Summary
Correction on slide last week under passive transport and osmosis: water always goes to where the concentration of solutes is higher. Primary diet is fruit and berries because they were mostly just gatherers. Way better than the north american diet in terms of balanced minerals, protein, overall nutrition: average 400-1000 hours gathering food during the week, so plenty of social time! Lowest limit of time spent gathering compared to agriculture farms today and in the past. 1000 years with both nomads and sedentary life with crops: plants or hunting depended on seasons. About 11,000 years ago, there was a large drought and it was hard to control how much food you could get, as well as a decrease in wildlife due to the drought. Used all parts of plant: parts for medicines, aromas, Traits that were selected in plants (selective breeding), may be helpful within the crop and beneficial for humans, but the plants will not survive in the wild.
