Guns, Germs, and Steal...Again, again

When you store food and have extra, it's called a surplus.  Animals that are domesticated have a lot of requirements.  They need to got along with other animals and humans.  There are 48 animals that can be domesticated but only 14 are.  Goats, sheep, pigs, cows, horses, reinder, yacks, mithans, watter buffalo, llamas, donkeys, 2 kinds of camals, and valley cattle.  New Guinea does not have animals like this.  Once again they have very bad geographical luck.  This is another reason why New Guineans are still have nots.
