Gerald Francis Joyce Quotes
… biologists are now going to be directing evolution.
He and others have already done it. Joyce's lab at the Scripps Research Institute was the first to produce a self-replicating in vitro system, capable of exponential growth and continuing evolution, composed entirely of RNA enzymes. Most politicians do not understand much about evolution and many actually believe that evolution has not been proven an is not what governs the development of species. And at some point these men and women will have to come to grips with this scientific reality and decide what if any restrictions there should be on the human control and manipulation of the evolution of different species.
Gerald Francis Joyce, Evolutionary Biologist, Winner of the Urey medal of the International Society for the Study of the Origin of Life, Quoted in Laurie Grant, “Biology’s Brave New World: The Promise and Perils of the Synbio”, Foreign Affairs, November – December 2013

What he thought was conceivable in the 1970’s seemed almost certain to come to pass 30 years later. Scientists had already altered the evolution of various plants and animals, and the complete human genome had been sequenced. The question will be not whether man will be able to control and modify his own evolution, but how should this be done and who should decide it. We have realized that man has already—unintentionally—altered the evolution of many species from passenger pigeons which are now extinct and the dog which coevolved with humans. Arguably, man’s development of the ability to control his own evolution is an evolutionary development itself. One great question for society is whether it is better to alter evolution unknowingly or in a planned, relatively controlled manner. For man to participate in the design of human evolution will be the nightmare of the Creationists who insist that evolution is too complicated to be somewhat of a random process and that there must be a designer who they assume is God. When man becomes the designer, that will be very disturbing. For most theologians, there will be little difficulty with the notion that God chose the mechanism of evolution and chose humans to give the intellect and knowledge to implement and design the evolutionary process.
Actually, while such selective breeding is possible in all animals, the selection for a single trait almost always produces other unintended and unanticipated traits and these could be devastating to the “new generation”, unpleasant, benign, or anything else. At the time selective breeding was the only possible tool to produce “desirable” traits in an animal or to eliminate what someone things of as “undesirable” traits. Today, our understanding of the human genome and genetic engineering offers a much more reliable possibility of affecting animal traits without as many risks of random and unintended consequences that are present with breeding.
Gore who generally was a progressive on almost all issues, was quite conservative when it came to human genetic manipulation and cloning. Scientists for whom Gore was a favorite politician based on his leadership of digital technology and the Internet and his Nobel prize winning work on environmentalism, but his stance in this quotation was puzzling to many.
Evolution sometimes produce or retain components that have no purpose or are even inefficient. But he is urging the biologist to remember that none of the life form were designed much less designed efficiently. We humans have an appendix for example, which does nothing positive and sometimes gets infected and kills us. Yet it is still there. We have so much else on the positive side that a few weaknesses are not material to our survival.
