How does Diamond refute the argument that the failure to domesticate certain animals arose from cultural differences?
Certain animals couldn't be domesticated for many different reasons:

  1. Wrong kind of climate for the animal
  2. Too large of an animal to control
  3. Not the right kind/ amount of food needed for the animal year round
  4. Some animals could be too dangerous to domesticate

What does the modern failure to domesticate, for example, the eland suggest about the reasons why some peoples independently developed domestic animals and others did not?

  1. Bad temper
  2. Shaky and nervous constantly (Tendency to panic)
