Talking about animals that will never be extinct that humans take advantage of. Animals that have been domesticated by people are the ones that will always be around. Animals we use for power or energy, food or fiber, entertainment, research, religious elements (this is why we’re going to focus on them) how humans make use of them now and in the past. . Don’t say cow being that’s not their species name, it’s cattle. Cows are mature females that are cattle. Singular annaplural. Cattle are always in herds, sheep are always in flocks.

Domestication - an animal that has been breed in captivity for some assistance or profit in a human community that we control their breeding, eating, etc. Wild (Tame)v (Captive) domesticated Bear Elephants Dog Wild animals are falling more in the middle cause we’re not trying to shape them, but conserve them. It involves a SHAPING. Is there a breed? Sheep started out being domesticated from their wool, humans reshaped them. Key concept is the notice of the breed. Are you trying to take them in a specific direction (ie. are they taller, should they produce more milk, etc) We forced the animal in that direction. 9/27/10
