ABSTRACT
The study of genetic histories reveals how all humans are more closely related than is generally expected and how “no man is an island entire of itself”. Such an approach demonstrates the complex networks, contributions, and overlapping of our ancestries, thus knocking down conventional boundaries and the erroneous, preconceived notion regarding human races. This chapter describes the use of the genetic markers as they relate to migratory events in ancient times, in modern times, and with regard to one’s personal ancestry. There could have been a common, now extinct, source population from which different migrations originated, thus resulting in modern, separate genetic pools that are “cousins” rather than ancestral in nature. In more recent years, the picture of world migrations and the relationship among all humans already depicted by uniparental markers has been corroborated by sequencing the entire genome.
