back in school

after missing three days of school Wednesday, Thursday and Friday. here we are on Monday back and school continuing to watch guns germs and steel. as a refresher, Jared diamond is in papua new guinea birdwatching, then one of the natives asks him why Americans have so much and they have so little. So Jared goes on a mission to answer that question.  13,000 years ago the middle east was much more fertile and better. humans thrived here and at this time were hinter gatherers. they would follow animals to hunt, kill, and eat. today the forest of new guinea is still a place for hunters. It takes great skill to capture an animal. gathering is done by women, they cut down a sago tree and take they core make pulp, and cook it. this food is low calorie and not enough protein to support a big population. Barley and wheat grow and they are a much more better source of food. 11,000 years ago, scientists believed that they created a food storage building in the middle of the village which allows them to keep them safe, the food will last longer and they people wont have to move and follow animals anymore. they figured out how to grow their own food. they only picked the plants that are better for them and those were the plants that would be grown and the traits were passed on. they became domesticated. china learned how to grow rice. South America learned to grow corn and beans. New guinea never had natural crops growing so they were at a disadvantage. all they can do is just hunt and gather. people in New guinea also have bananas but sometimes have to resort to eating spiders for nutrients.
