DNA GPS

Genes not only give you a key to different traits and disease, they can also tell your hereditary history.  Eran Elhaik from the University of Sheffield has created the Geographical Population Structure algorithm with help from participants from the Genographic Projecy  The way this works, if once you have your DNA sequenced by another company, input the information in the system.  It will then be able to show you where your roots are from.  In addition to showing the evolution of humans, it may also help with medical history.
