Back to Germs, Guns and Steel...

Today we finished Germs, Guns and Steel. Tomorrow is our test on the documentary, I hope my notes and blogs help me prepare for the test. Here are the notes we took today:

• Gwar, archaeological site, 9,000 years old, about 2,500 years after Draa, had a few hundered people, 
• Houses had windows for ventilation/AC
• Walls/Floors were plaster
• Homes were appearing
• Decoration
• Limestone + Fire = Liquid Steel
• Due to poor agriculture, New Guineans couldn't support specialist like metal workers
• Eventually, the fertile crescent became infertile, it was over farmed, and too dry
• When people moved from the fertile crescent, they moved directly east and west in hopes that on the same latitude line, the same plants would grow, and the same type of soil and growing methods would work
• Food was the main source of a modern civilization
• There was no cattle in the Americas in ancient times 
• 100 million cattle in U.S.
• Americans consume 20 million tons of wheat of year
• One race is not superior, just some did not have the same resources others had
