The limited nature of organic change has been common knowledge among farmers and breeders for centuries. You can breed for faster horses or larger apples, but eventually you reach a boundary that cannot be crossed, no matter how intensively you continue the breeding program. A horse will never be as fast as a cheetah, or an apple as large as a pumpkin. What's more, as you approach the boundary, organisms become progressively weaker and more prone to disease, until eventually they become sterile and die out. This has been the bane of breeding efforts since the dawn of time. Luther Burbank, possibly the most famous breeder of all times, suggested that there might even be a natural law that "keeps all living things within some more or less fixed limitations."
