I'm not sure about 99% of the whole world, but your point is certainly correct, and I spoke about it earlier in the thread too. But for european, mediterranean and middle east population it is certainly true. There is in fact a very interesting mathematicsl study published recently that concluded that all present day europeans and descendants are all related to each other and the most recent common ancestor lived only 1000 years ago. Therefor, everyone of us descends from Charlemagne and any other person that lived before and left descendancy, including the romans.
