S&T Watch-4: "Changes in DNA discovered"

Scientists have spotted signs of recent evolution in the human genetic code, suggesting that diet and changes in habitat have had a lasting effect on our make-up… Among the most striking changes is the emergence of a gene now found in 90% of Europeans that allows them to digest milk into adulthood, a likely consequence of dairy farming. The gene will probably be found in everyone in a further 1000 years, the researchers say.
