Even after thousands of years of evolution, the human race is not perfect: it is ravaged by disease and limited by nature. Yet in recent times, researchers have begun to establish an advanced understanding of humanity's underlying genetic code. The Human Genome Project, now completed, has provided a map of the complexities of human DNA, allowing researchers to begin examining the purpose of each gene. When combined with selective embryo implantation, now occasionally used to avoid hereditary diseases or to choose gender, genetic discoveries can become a kind of artificial evolution. By modifying genes in embryos before implantation, humanity has the potential to control many aspects of its offspring. The human race should welcome human genetic engineering, because the technology will inevitably be used, is ethically sound, and offers opportunities for progress in preventing disease and improving the human body. Modification of the human genome will occur as a natural result of genetic engineering. research, even if it does not directly concern the remodeling of human DNA. In areas such as agriculture and livestock, genetics already plays an important role in determining success. Within a few decades, genetically modified crops moved from laboratories to farmland, foreshadowing the future success of similar projects in humans. The techniques used by scientists to modify the nature of plants predate the slightly modified procedures that are used today to modify the DNA of animals. In Redesigning Humans, Gregory Stock describes one specific way that genetics is already being used to determine traits, saying, “This is not improvised genetic design.
