Two theories of how animals came to be domesticated - ANSWER-Adoption Theory: humans made it
happen by capturing/taming/raising baby wolves (only let the tamest wolves breed and eventually may
not be wild/unpredictable); human initiated; artificial selection
Adaptation Theory: wolves chose domestication because the tamer wolves could get more food if they
weren't afraid of people and their offspring are more likely to survive; natural selection; animal initiated
What is the difference between Artificial vs. Natural Selection? - ANSWER-
Behavioral traits that facilitated domestication - ANSWER-

The fox farm experiment - what did we learn about domestication from it? - ANSWER--their adrenaline
levels went down which has a correlation to coat color because of their hormones
-hormones help change the genetic structure of animals

down, and their tails went up
