It is not just a matter of man being able to reduce the time it takes to produce varying characteristics and traits, but also a difference between artificial selection and natural selection....
So artificial selection is quite a bit different than natural selection in this way. I don't mean to be a nit, but it's an important distinction, especially for those with little understanding of how evolution works to begin with. To even ask the question, 'why hasn't evolution produced a chihuahua?', shows an astounding ignorance on the subject.
