Scientists have created a DNA tool that can accurately identify ancient populations, and may be used to test an individual's similarity to ancient people who once roamed the earth.
Currently the study of ancient DNA requires a lot of information to classify a skeleton to a population or find its biogeographical origins.
Scientists at the University of Sheffield in the UK have defined a new concept called Ancient Ancestry Informative Markers (aAIMs) - a group of mutations that are sufficiently informative to identify and classify ancient populations.
