Up for adoption

Further to our piece last week on the scientific research that could identify your surname by examining your Y chromosome, except of course if you were a woman or someone who had changed their last name.
Angela Walker, at Skynet Applied Systems, points out that: ‘it wouldn’t be much use if you were adopted either.’ In fact, as a way of finding out your surname, it’s probably not quite as useful as asking your postman, but who are we to stand in the path of scientific invention?
