We are all cousins

If you go and trace your family tree back to the time of the ancient Romans you will have a common ancestor with any one on this planet. We all even have a common ancestor that lived in Taiwan at about 300 B.C. Every one is at the least 50th cousins. Also if you are the same ethnicity and your ancestors are from the same country's,then it is more likely that you are only 10th cousins, or closer.
