A MUTATION that causes some Asians to flush red when they drink alcohol may have evolved to help their ancestors cope with rice wine. A genetic study suggests that it evolved around the same time as Asians were starting to farm rice and ferment it into boozy drinks. Bing Su, a geneticist at the Chinese Academy of Sciences in Kunming, studied the genes of 2275 people from 38 east-Asian populations. He was looking for a mutation that modifies the gene responsible for the enzyme alcohol dehydrogenase (BMC Evolutionary Biology, vol 10,
