In the past 10,000 years, people have been evolving rather quickly, though this speed doesn't seem fast enough for everyone, says this US News and World Report article. Anthropologist John Hawks points out that some people can now digest lactose and others have some resistance to smallpox or malaria even though those genes used to be rare. But today's world is changing so quickly that Oxford's Nick Bostrom says biological evolution isn't keeping up and some people are turning to preimplantation genetic diagnosis to choose some of their child's traits. However, bioethicist Thomas Murray adds, "Our capacity to do these kinds of intentional designs is vastly overrated."
