Guns, Germs, and Steel (continued)

The large four animals and the best growing crops was in the middle east and was called the fertile crest. This was leading towards the first civilization. Some of the houses had some of a air conditioning. Some people created new skill and new technology from farming like making plaster. Learning how to make fire was a major part of creating technology. You use fire to bend steal and you can make weapons and tools, new technology. The people in Newguinea couldn't make new tools and technology because they spent all their time feeding themselves. The fertile crest changed, the climate was dry and it couldn't support all the farming and people. Entire communities had to move just because there was no arable land, but once again geography was on their side. Right next to the middle east there was many places that also had great crops and animals, they werent isolated. Wherever wheat and barley spread they helped form a civilization. When wheat hit Egypt and Europe it  help them out a lot and helped during the renaissance. European took the domesticated animals to the United States where non were. That pretty much raps up the movie! Guns, Germs, and Steel thats it.
