Human evolution is speeding up
Humans have moved into the evolutionary fast lane and are becoming increasing different, a genetic study suggests. In the past 5,000 years, genetic change has occurred at a rate roughly 100 times higher than any other period, say scientists in the US. This is in contrast with the widely-held belief that recent human evolution has halted. ... "Nobody 10,000 years ago had blue eyes," Hawks said. "Why is it that blue-eyed people had a 5% advantage in reproducing compared to non-blue-eyed people? I have no idea." http://news.bbc.co.uk/2/hi/science/nature/7132794.stm וגם: http://www.latimes.com/news/science/la-sci-evolution11dec11,0,5882337.story?track=rss
