The Prodigal "Son"
Lots of surprises with this one. The relationship between the Scandavian and Germanic languages are fairly obvious, but below those you have a relation arising from a common source between English and a language that was once spoken on the steppes of Russia, and by the Dacians on the Adriatic Sea, across the water from Italy.
We can almost imagine a people migrating – over the course of hundreds of years – from the East, across the Baltic countries, to the North across Russia, and West again once they reached the sea. The Sanskrit suggests that they began in modern day India.
The prodigality of “son” suggests that their path was open, that they were travelling over unpopulated land. Later this unpopulated land was settled and, probably at the outbreak of intertribal conflict, some stayed while others left, either to escape war, or because they were defeated and exiled.
The diffusion suggests that they migrated across land at first, then by ship. It’s plausible to assume that their culture mutated as the migrants continued adapting to their environment, and what began as a land-based, agrarian culture transformed into a sea-based culture for those who were compelled to continue wandering.
Who were they, how long did their journey take, and when did it happen? The PIE hypothesis situates these events 6000 years ago, taking place from between 4000 to 2500 BC.
