M91(BT)

M168(CT)’s parent was M91(BT) and his sibling was L419(A1b1). “Macrohaplogroup BT has been found in populations on every continent, since prehistoric times.” It is believed that all non-African people are descended form M91(BT). In my mind this conflicts with the statement above about M168(CT). But then we have a bunch of different scientists working on this all with their own ideas which have not been fully argued out and agreed upon.
