        Summary
        World map of human migrations, with the North Pole at centre. Africa, harboring the start of the migration, is at the top left and South America at the far right. Migration patterns are based on studies of mitochondrial (matrilinear) DNA. Dashed lines are hypothetical migrations.
        Numbers represent thousand years  before present.
        The blue line represents area covered in  ice or  tundra during the last great ice age.
        The letters are the  mitochondrial DNA  haplogroups (pure motherly lineages); Haplogroups can be used to define  genetic populations and are often geographically oriented. For example, the following are common divisions for mtDNA haplogroups:
        
         - African: L, L1, L2, L3
 
         - Near Eastern: J, N
 
         - Southern European: J, K
 
         - General European: H, V
 
         - Northern European: T, U, X
 
         - Asian: A, B, C, D, E, F, G (note: M is composed of C, D, E, and G)
 
         - Native American: A, B, C, D, and sometimes X
 
        
        Data derivation
        
        
         - All migration data based on  mitomap.
 
         - Geographic data from  
 
         - and adding the following data   we get this interesting result
