Combining DNA studies with archaeologic evidence, it has been possible to map out the migratory paths of prehistoric tribes and their inter-relationships. DNA samples show that the Gaul tribes originated from the Parisii
tribe which inhabited the area of modern Paris around 4000 BC. The Parisii tribe, approximately 2000 strong, was highly migratory and headed north where they would have encountered the English tribe.
It was at this meeting approximately 3975 BC that the Parisii tribe divided with approximately half the tribe forming the first Parisii oppidum
with the other half of the tribe continuing its migration. Archaeological evidence indicates that the nearby English village of London predates the Parisii village by approximately 25 years so it is possible that the Parisii tribe were emulating the English when they settled their first village.
Regardless of the reason for settling so close to London, the result was that the two villages exerted such a tremendous cultural influence over one another that it was previously believed that the Parisii tribe was originally of Celtic (English) origin
. Recent DNA evidence has shown that the two races are genetically unique and that any relationship between the two is the result of cultural influence only.
The migratory portion of the Parisii tribe headed north where they would have encountered the Viking territory. The tribe then veered east until then ran into the Grunzen Neanderthal tribal territory. The tribe then veered southeast until they encountered the Turkish tribal territory.
