"The hybrid frustrates the purpose of creation. All things, we are told according to Genesis, were created with their seed in themselves, destined to be fertile. Hybridization seeks to improve God’s work. It seeks to gain the best of two diverse but somewhat related things. The result is a limited advantage but a long range launched including sterility. Second, these laws clearly require a respect for God’s creation. We are not to change one kind into another, or to attempt it. All things we are told were created good. Now when we hold to evolution we cannot see all things as created good. Because evolution is the survival of the fittest, and the best you can say about anything is that it is the fittest. Not that it is the best, not that it is morally the most desirable thing. And though it has survived thus far it may not survive in the next ten thousand years, so that man for example, we are told may be a mistake. Thus we cannot under an evolutionary perspective see all things as created good. But man under God has been created good and the world around him has been created good. Man can kill and eat plants and animals to use this creation under God’s law. But he cannot tamper with it, he cannot hybridize; which is to violate God’s kind. And the penalty for it, of course, is sterility. You can cross a horse and a donkey, but the mule is sterile. You can put all kinds of new variety of squash and carrots and the like on the market, but the penalty for these is sterility. They will not produce a seed. And while they will have certain advantages --the mule has certain advantages over the horse-- they have marked disadvantages, and a greater frailty, sensitivity, nervousness (as with the mule), so that they are a real handicap."
