According to Genetic Genealogy, the DNA Ancestry Project discovers ethnic origins of people by looking at their DNA and DNA mutations. For example, DNA mutations during human migration out of Africa links certain groups of people to certain places according to specific mutations. These mutations allow people to trace their distant and recent ancestral lines throughout the world.Continue Reading
The DNA Ancestry Project looks at a person's DNA markers then compares those markers to other known DNA markers throughout the world. It shows where that person's ancestors originated, where they migrated and where they dispersed.
This project determines a person's haplogroup, which are common ancestors that lived thousands of years ago. The project finds out where this haplogroup lived, such as Europe or Africa. It also discovers someone's specific lines of descent. For example, she might belong to the Jewish Cohanim line or the Niall of the Nine Hostages.
The DNA Ancestry Project cannot yet distinguish between whether a person's ancestors were Spaniards or Italians. The geographic locations determined by the DNA tests are quite a bit wider, divided into Scandinavia and Southern Europe, for example. Most people who take these tests find that they have Viking and Roman ancestors. As of 2014, there are more than 24 companies offering genetic ancestry testing.Learn more about Internet & Networking
