Ever been tempted to do a DNA spit test to see which ancient groups you're descended from?
Such tests use autosomal testing, which involves comparing parts of your genome with bits from people all round the world to find the commonalities.
But is there an easier way?
If you trace your family tree back far enough, you'll find almost all Europeans alive today are related to all the Europeans of 1,000 years ago. So you're most likely part Neanderthal, Viking, Celt and more.
