Smart doggy, wise humans: The sooner we give up on preferred racial purity, the sooner racial prejudice will wither away.
This is a sensitive, complex issue. It is possible that gene pools are enhanced by mixing gene pools in any species, including homo sapiens. There is, however, no doubt that the dog pictured above would be the match for any purebred in such things as intelligence, health, longevity, and agility. The situation with regard to breeding between us and our favourite companion animal is not exact, but it is suggestive. More important, when families like those pictured above become accepted worldwide as normal, it is hard to see how the supreme folly of racial prejudice could have much purchase.
