Today in class we continued to watch Guns, Germs, and Steel. I learned that people in China grew not wheat or barley but rice. In America, they grew corn, squash, and beans. In Africa, they grew sorghum, yams, and millet. In Papua New Guinea, people have farmed there for 10,000 years. In the Middle East people evolved 10,000 years ago. They eat giant spiders for protein because they didn't have much protein. If you had the most product able crops, you had the most productive resource. It also depended on where you are in the world. Wheat is 1/5 of calories people eat. 9,000 years ago villages got bigger and had a good source of food. If you wanted meat, you had to hunt it. People raised animals like goat and sheep and ate them.Goats and sheep were also the first animals domesticated. In other parts of the world people used the the wheel and plow to farm. In Papua New Guinea, they didn't used the wheel and plow because they had no animal to pull it. There are 14 species of animals other 100 lbs have been domesticated. They are goats, sheep, pigs, cows, horses, donkeys, Bactrian camels, Arabian camels, water buffalo, llamas, reindeer, yaks, mithans, and Bali cow. Only the llama is from South America and the rest are from Africa or Asia.
