Scientists were able to pinpoint the nomadic patterns of our ancestors who migrated from Africa to different continents of the world by analyzing and mapping genetic profiles, as reported on The Conversation.

Evolutionary biologists claim that our ancestral lineage can be traced back to Africa. However, they were not successful in explaining the patterns of migration which led to the development of different races. The answers to that question can now be explained using three genetic mapping of over 200 populations across the world.

The findings concluded that humans first traveled out of Africa going to the middle east and Europe. It then furthered to the Northeast going to the Americas. The researchers also found out that humans today could have been interbreeding the offspring of Neanderthals of Eurasia and Denisovans of Asia. There were very few differences in the genetic make-up of the African nomads who went out of Africa to the Africans who stayed because they theorized that only a few group of African migrated which delimited the genetic diversity between African nomads. A group of Africans coming from the mainland then migrated that became the first habitats of Australia.

According to the Simons Genome Diversity project, which analyzed 142 populations across the globe, they concluded that several factions of modern African hunter-gatherers departed from Africa that went to be non-Africans we know today.

Another research suggests another major migration of mankind which suggests that there have been migrations to Asia earlier that the major migration mentioned earlier. It also theorized that modern human species migrated way earlier than what was previously believed.

These conclusions supporting the "Out of Africa" theory were derived by cross-analyzing the DNA from a gene pool of populations found in different parts of the world. By keeping on updating the genomic databank we may able to further establish our very own evolutionary history for a better understanding of our origin.

These different research were originally published in Nature.
