Chapter 4
Farmer Power
Agricultural Societies
• Agricultural societies produce more food and thus more people.
Meat
• Meat from livestock replaces wild meat, animals also provide power to pull plows and fertilizer.
Sedentary Existence
• Sedentary existence leads to shorter birth intervals for women (4 years for hunter-gatherers versus 2 years for agriculturalists), contributing to higher population densities
Specialists
• Food was stored allowing existence of non-food producing specialists:– kings– bureaucrats– soldiers– priests– artisans.
Fiber
• Crops and livestock provide natural fibers for:– clothes– blankets– nets– rope
Big Animals
• Big animals provided transport by riding:– horse– donkey– yak – reindeer – camels
Animal Utility
• Horse, donkey, yak, reindeer, camels plus the llama also used to bear packs.
• Cows and horses were hitched to wagons
• Reindeer and dogs pulled sleds.
Horses
• Horses were the most potent military technology of ancient warfare on the Eurasian continent.
Germs• Germs evolved in human societies with
domestic animals: smallpox, measles, flu are derived from animals.

History's Haves and Have-nots
Unequal Conflicts
"Much of human history has consisted of unequal conflicts between the haves and the have-nots: between peoples with farmer power and those without it, or between those who acquired it at different times."
Crop Domestication
• Agricultural production originated independently in only a few places in the world at widely different times.
Crop Domestication
• Every other place got it as a cultural package of both domesticated plants and animals.
• Can trace by archeology where a crop was domesticated.
• Clues include finding wild varieties growing nearby.
Teosinte
Often areas of most intense production are not where domestic crops originated.
Global Potato Production
Where Crops were Domesticated
• Five areas where crops were domesticated independently are:
• Southwest Asia (Middle East): – wheat, pea, olive
Where Crops were Domesticated
• China: Rice, Millet
Where Crops were Domesticated
• Mesoamerica: corn, beans, squash
Where Crops were Domesticated
• Andes: potato
Where Crops were Domesticated
• E. USA: sunflower
Other Domesticated Crops
• Other crops were domesticated in other places probably after domestic crops arrived from these five centers, and people were already committed to farming.
Adoption by Hunter-Gatherers
• Sometimes arrival of domesticated plants and animals were adopted by hunters/gatherers– Egypt– Atlantic coast of Europe– South Africa– Native Americans in U.S.
Displacement of Hunter-Gatherers• Sometimes hunters/gatherers were displaced by
agriculturalists – South China expansion into Philippines and Indonesia– Bantu expansion over subequatorial Africa– European expansion into
• California • Pacific Northwest • Argentine pampas• Australia• Siberia
Bantu Expansion
Head Start
"The peoples of areas with a head start on food production thereby gained a head start on the path leading to guns, germs and steel. The result was a long series of collisions between the haves and have-nots of history."
Chapter 6
To Farm or Not to Farm
Food Production• Food production often led to
– poorer health– shorter lifespan– harder labor for the majority of people.
Adoption of Agriculture
• Adoption of agriculture was not a discovery of food production nor an invention.
• It was a process of cultural evolution.
Evolution of Agriculture
• Without having seen an agricultural society, how could first people who adopted agriculture have consciously chosen it?
• Food production evolved as a by-product of decisions made without awareness of their consequences.
Piecemeal Adoption of Agriculture
• Many hunters and gatherers adopted some agricultural practices or sedentary life while continuing hunting and gathering:
– Pacific Northwest Native Americans.
Piecemeal Adoption of Agriculture
• Also, many agriculturalists are nomadic, and many hunters/gatherers manage the land they live on.
Piecemeal Adoption of Agriculture
• Agriculture was often adopted piecemeal as it became desirable.
Factors in Adoption of Agriculture
• Relative decline in availability of wild foods. – As human populations
grew and animal populations shrunk, agriculture became desirable
Factors in Adoption of Agriculture
• Climatic changes after last ice age increased range of domesticable plants.
Factors in Adoption of Agriculture
• cumulative development of technologies for harvesting and storing wild foods facilitated agricultural life– sickles– baskets– roasting techniques– mortars and pestles.
Factors in Adoption of Agriculture
• Autocatalytic rise in human population with agriculture, and agriculture with human population. – Population was rising
due to increased technology and thus demanded agriculture.
– Agriculture itself results in ever increased populations.
Factors in Adoption of Agriculture
• At boundary of agriculturalists and hunter-gatherers, denser population of agriculturalists allowed displacement or killing off of hunter-gatherers.
• Where there were only hunter gatherers, those who adopted agriculture outbred and displaced or killed off those who didn't.
Hunters of the World
20th Century Hunter-Gatherers
"Those few peoples who remained hunter-gathers into the 20th century escaped replacement by food producers because they were confined to areas not fit for food production, especially deserts and Arctic regions."
