Response to Jared Diamond's thesis

I think that Jared Diamond is correct in believing that expansion of civilization is largely due to geographical luck. Because you need a crop that can grow in large quantities from one seed and produce many fruits to feed many people. The plant also needs to be rich in nutrients. In Europe and the middle east that plant was wheat and barley. In Asia it was rise, in the Americas it was corn. However in New Guinea there was no crop like that. Another thing that you need for civilizations to develope is animals. In Euroasia there were 13 species od animals that are domseticated to this day. One was in America, however in New Guinea there were none, except pigs, who were brought there from Asia. I think that this is largely the reason that civilization never got under way in New Guinea. Aside from that there is the fact that it was on an island and there wasn't much space to expand to. In Mesopotamia there was perfect climate, cows, pigs, sheep, and goat. Four species of animals that are very usefull when domesticated. There was also barley and wheat, and a good climate. When the climate changed the people from Mesopotamia had places to go. When they went to Egypt there was a huge boom in civilization, proving that what the Mesopotamians had was very helpfull for civilization.
