The cow Bos primigenius (which is bred for meat and milk) has a smaller brain and larger eyes than closely related wild species of ungulates. These traits most likely arose by ________.

#Unit 11. Evolution and Behavior
  1. natural selection, because these traits evolved in the population over time

  2. natural selection, because these traits were not consciously selected by humans

  3. artificial selection, because changes in these traits co-occurred with human selection for high milk output and high muscle content

  4. artificial selection, because these animals differ from their close relatives and common ancestor
