Just when I thought I was getting it? On the MTDNA everytime I check new countries emerge? The sequences so far are H, H1, H10, H2, H2b H3, H4a ,H7, HV, R, U, V and has a numerical number assigned after each one or country. Is this recent origins? or thousands of years ago? Where are the databases comming from? Anyone.

Thank you in advance.
