Patterns of genomic traits have the power to identify individuals and also populations. By following these traits through time we are able to spotlight prehistoric migratory events that we are otherwise not able to detect. 

I will describe two events that we have recently identified with paleogenomics. The first one being that of the early colonization of Scandinavia, and how this peninsula came to be inhabited by anatomically modern humans. The other one is a description of the dynamic history of nomadic groups on the western Steppe. This area was a melting-pot of different groups during the late Bronze Age and early Iron Age.
