If you look on National Geographic they show the population move. Africa first people, then north to Egypt,to the right to India then left into Europe if I remember rightly. We all come from Africa originally. I'm always amazed when archeologist in Britain dig up skeletons and check their teeth to find they came from Asia ( Iran and Turkey area)of the mediterranean, people they really got a lot more than I ever thought trading spices etc.
My husband had his DNA done, I can't remember when but he is on Familytreedna - Code/coad etc. The odd thing with that is the Code families lived 20 miles apart in Ontario and 20 miles apart in Wicklow and no DNA match!!AC
