I think you should read my statements more carefully There you will find answers to your questions There basically exist no new and old lineages The Europid race diverged ca   years ago in the Near East and between   years ago expanded to the whole Eurasia and later in a partly mixed form as far as to America The Mongolid race originated from one branch of the Coastal Clan I ie factually from one branch of the australoid race So far I havent studied when it happened but it must have been quite shortly after they reached SouthEast Asia ie some   years ago When they came into contact with old europids ONQ Ylineages about   years ago they must have been already well adapted to the Siberian climate The degree of adaptation to the cold climate in mongolids is higher because they have been exposed to it maybe   years longer than Europeans and of course the Siberian climate may have been even generally harsher than in Europe
