Debunking 'Humans Are Getting Dumber' Study
George Dvorsky, io9
A new study published in Trends in Genetics is suggesting that humans are slowly but surely losing their intellectual and emotional capacities. According to Stanford University's Gerald Crabtree, humanity peaked in intelligence about 2,000 years ago, and we've been heading downhill since then, owing to genetic mutations that aren't being selected against. It's possible that Crabtree is right — but his argument may be a moot point.
