Document Summary
Chapter 3 power of genes : domestication of plants and animals, artificial selection: ie manipulating to there benefit. Phenotype is a trait: behavior or physical characteristic seen earliest in dogs, domesticated wolves, not tamed wolves. Domestication is when they lose wild instinct and breeding cycles, genetically preprogrammed to be purposeful for humans. Dogs were the first domestication around 15-20,000 yrs ago. Taken the wolf and made it into something cute, but still have the sane genes, humans have selected flavors of genes, and selectively breed to get certain characteristics, have all diff sizes and shapes however same characteristics. On the surface we look different however we all have the same genes, if you tweek it slightly you get different version of the genes ie phenotypically diverse. They continue to do this for there own purpose to breed diff types of dogs, aggressive or more passive, different qualities.
