Geneticists can track the paths of ancient migrations by studying the markers in Y chromosomes of men from different parts of the world.
Scientists trace the path of human migrations by using bones, artifacts and DNA. Ancient objects, however, are hard to find.
DNA from contemporary humans can be compared to determine how long an indigenous population has lived in a region.
The latest studies survey swathes of entire genomes and produce maps of human movements across much of the world. They also describe how people’s genes have adapted to changes in diet, climate and disease. (Scientific American, July 2008)

Very interesting article. Some people have been contacting me assuming that the DNA was the final answer. I have to say that it is not. When you find a DNA connection, you must trace that particular lineage. Somewhere in there, you will find a 25th cousin, ggg-parents, or whatever. In other words, you have part of the genealogy. Now, you need to get in there and dig.
