Quote of the Day

[W]e can paraphrase the Italian geneticist Guido Barbujani: imagine that at some time in the future Indian astronauts colonise Mars, and geneticists then type their Y chromosomes. We may well find that their lineages date back to 9,000–20,000 years ago. But we would not be wise to infer that they have been living on Mars for 9,000 years.
