An interactive world map of human genetic history reveals
likely genetic impacts of historical events
When individuals from different groups interbreed, their
offspring's DNA becomes a mixture of the DNA from each admixing group. Pieces
of this DNA are then passed along through subsequent generations, carrying on
all the way to the present day. Researchers from the Max Planck Institute for
Evolutionary Anthropology in Leipzig, Germany, Oxford University and University
College London (UCL) have now produced a global map detailing the genetic
histories of 95 different populations across the world, spanning the last four
millennia.
