Some researchers aren't happy with the current view of evolution. They picture it as being faster than many think and capable of genetic changes being even faster. One case they cite is the ability of adult humans to digest cow milk. It appears that the sudden increase in people who had the gene needed to do that mushroomed in the last 50 centuries -- a lot faster than traditional Darwinists would have predicted.
Academic radicals and futurists try to make a case for human intervention to speed up desired genetic changes. That's a scary thought unless morals and ethics are the guiding light in any such decisions. Could we leave such decisions up to companies who might profit from genetic changes or from causing the changes to happen? Whose morals do we use? Who gets to decide and for whom?
