destinyland writes "One in 12 men suffers from colorblindness, though '[t]he good news here is that these folks are simply missing a patch of DNA ... which is just the kind of challenge this Millennium is made for. Enter science.' But NPR's Moira Gunn (from Biotech Nation) now asks a provocative question. Is it wrong to cure colorblindness? She reports on an experiment that used a virus to introduce corrective DNA into colorblind monkeys. ('It took 20 weeks, but eventually the monkeys started distinguishing between red and green.') Then she asks, could it be viewed differently? 'Are we trying to 'normalize' humans to a threshold of experience?'"
