Guns, Germs, and Steel

Tomorrow I have a test in human geo. I am going to study the notes that I have taken. I am going to pay extra attention to the 5 places that civilization began, and I will study the notes from the video. Here are some last minute notes from the video:

• The animals had to be social animals
• If humans can control leader of the pack, then they can control the entire pack
• Zebras can be as helpful as horse, but since they live in Africa they are skittish and vicious
• Dacthian and domestic camel
• None of those animals are from Papua New Gatineau
• South America has lama
• Asia, North Africa, and Europe have 13 of those animals  
• Mesopotamia wins
• Made plaster from limestone
• Work with fire was the first step to steel
• Fertile Crescent
• Settlement became bad
• Places of the same latitude (East and West) share the same climate and length of day
• There would be no cattle and wheat in America without the fertile Crescent
