Harvard Economist Suggests Humans Are Still Evolving
Harvard economist Jonathan Beauchamp has conducted a study of lifetime reproductive success (rLRS) of a small segment of the U.S. population and has concluded that there is evidence that humans are still evolving. In his paper published in Proceedings of the National Academy of Sciences, he describes the study he conducted, his results and why he believes we are still evolving despite our control over our environment.
As Beauchamp notes, many in the scientific community have come to believe that humans stopped evolving approximately 40,000 years ago—shortly after the advent of agriculture. But he notes there is also evidence that refutes such claims, such as studies that have shown that people developed an ability to digest milk and to live at high altitudes much more recently.
