The Future of Man–How Will Evolution Change Humans?
Peter Ward’s article, Future of Man – How Will Evolution Change Humans? in Scientific American Magazine discusses how we may have and continue to shape our evolution through changing the environment through technology. A study of genetic markers from 270 people showed that humans underwent some evolution as little as 5,000 years ago. In another study, large data sets of genetic variation showed how changes to the genome increased survival chances through increased resistance to diseases like Lasser fever and malaria and may explain differences in peoples’ ability to digest milk in different regions of the world.
Whatever the future holds for human evolution, it makes for interesting speculation and food for thought…for the time being.
