> If eugenics doesn't work then how come every single Border Collie is smarter than every single English Bulldog?

This statement is worse than wrong; it's nonsense.

Even if you come up for some very specific metric of intelligence that you think is valid (which will always involve the use of some limited test constrained by subjective considerations) you're still wrong! Not every single Border Collie will perform better than every single English Bulldog, at best you will find some consistent comparison between averages, which is absurdly far from the same thing.

Let's say that our measure of intelligence is "good at herding sheep". Are you certain that all we will find is "some consistent comparison between averages"?
