Guns Germs and Steel Part 3

Humans started interacting with animals in the Middle East. They started domesticating them.  They began with plants and hunting and gathering and gradually advanced to domesticating animals. When you have an excess of food you don’t have to worry about starvation and you can have time to figure out how to make granaries and other ways for food preservation.  They people in Papua New Guinea just spend all of their time getting and preparing the food.  As well as for meat, animals could be used for milk, and skins for clothes for extra warmth. Animals could eat the remains of crops for food.  Plants and animals are beneficial to each other as well as for the people. Use their waste for soil and fertilizer.  And you can reproduce them so they won’t have to constantly hunt them down.  They now have meat right there under their control and no need to keep hunting but you have it right there.  They also invented the plow.  They domesticated the animals and trained them to pull a plow.  They would train the big animals for this; this way is faster and more efficient.  The animals will work and work and work and you don’t have to make the people do as much labor intense work.  The plow was the most powerful tool at the time.  It allowed the farmers to make for food for more people.  People in Papua New Guinea have pigs and deer but they can’t domesticate them.  The only muscle power they have for the jobs are human muscle power. Domesticated animals need to get along with humans.  Out of 148 animals, only 14 have been successfully domesticated. They include; Goats, Sheep, Pigs, Cows, Horses , Donkeys, Camels, Water buffalo, Llamas , Reindeer, Yacks, Mithan, Valley cattle , Some Birds, Fish , Reptiles, Large plant eating mammals.  Some zebras would be good but they have a vicious streak that humans cannot tame.
