G1 persons today are found in highest frequency in Iran. Thus an argument can be made that the common ancestor of G1 persons lived in Iran and very little movement has taken place since then. G1 is found in next highest frequency in the countries adjacent to Iran on the north and west. In addition, there is a pocket of G1 persons in Kazahkstan. Very few G1 persons are found in Europe or Africa. Very little is known of how G1 persons may have moved around. In addition, no attempt will be made here to break down G1 into its known components. As explained in the categorization section of this site, it can be difficult to distinguish G1 only persons from G1a persons. And vurtually no G1b samples are available. Among G1 persons of European ancestry, the majority are Jewish men with recent ancestry in various parts of northeastern Europe. How the ancestor(s) of these men arrived in northeastern Europe is currently unclear.
Based on available detailed samples, it is generally estimated that the G1 mutation (M285) occurred about 4600 B.C.E.
The one available detailed sample from India suggests the common ancestor he shares with those G1 persons in Europe and Iran-Turkey-Middle East lived about as far back as the origin of G1.
The Kazakh G1 group shares a common ancestor with the Ashkenazi Jewish G1a group generally about 1200 B.C.E. Diverse Europeans are the next nearest relatives, and common ancestors with the Middle Eastern and Indian components seem much older.
The Ashkenazi Jewish G1 and G1a groups are not closely related. The common ancestor of the two groups generally lived in the earliest days of the origin of G1. In our detailed samples, the Ashkenazi G1a group's nearest relatives are found among the Kazakhs, and the Ashkenazi G1's groups nearest relatives are found among scattered Europeans generally with shared common ancestors in the latter situation about 4300 B.C.E.
The Middle Eastern detailed sample from Yemen has a shared common ancestor with various Europeans about 3100 B.C.E., and these are his nearest relatives. The Jewish G1a persons are next nearest in relationship.
