Israelites, Josephus, and the Parthian Empire

Flavius Josephus is one of the best 1st Century historians we have from the Middle East. He was employed by the Romans, but he was a Jew, giving him a very unique perspective having lived through the destruction of the Jewish Temple in 70CE. The main reason I bring him up now is because of what he implies in his writings about Central Asia and the possible connections with the Y-Chromosome Haplogroup K, but more specifically the child haplogroups, R and Q (See map). Below is one of his quotes not commonly known (especially amongst secular population geneticists) regarding the ten lost tribes of Israel, who were brought into Assyrian Captivity more than 800 years prior to the life of Josephus:

"...wherefore there are but two tribes in Asia and Europe subject to the Romans, while the ten tribes are beyond Euphrates till now, and are an immense multitude, and not to be estimated by numbers." Antiquities of the Jews - Book XI (Ch. 5)

When Josephus was writing the “Antiquities of the Jews”, the Euphrates River had been the armistice line for many many decades between the Roman Empire of the West and Parthian Empire of the East. He was treading on thin ice to even bring up this subject and if you read the whole passage you'll see he never brings up "Parthia" by name and for good reason, most notably: self-preservation. Rome and Parthia were about to start up their wars again. In the next century, both sides lost so many men in their conflicts that Rome would soon be fighting civil wars and Parthia would completely collapse. The surrounding Saka/Scythians, many not formally a part of the Parthian Empire, were strong allies with Parthia and even fought together against Rome (many believe the Parthians were of Scythian stock themselves).

Parthia's disintegration in particular is what many historians believe was the catalyst for what became known as the "Great Migration Period" where a flood of humanity poured into Europe from Central Asia. You’re probably aware of these migrating peoples: the Huns, Vandals, Saxons, Angles, Goths, Ostrogoths, Visigoths, Franks, etc. They show up two hundred years after the Parthian demise… exploding out of Asia. What is noteworthy, many centuries later, is the fact that the Saxons called back to "Scythia" for re-enforcements when invading Britannia (British Isles).

Personally, I think population geneticists are exaggerating about how much time exists between us and the originators of various haplogroups, largely because of radio-carbon dating. This isn’t based on gut-feeling alone, for in much of my reading so far, I’m convinced the geneticists have under-estimated how rapidly the human genome is mutating and they overlook common historical migration facts. For example, Central Asians rapidly poured into Europe within a few hundred years to a couple thousand years, NOT tens of thousands of years.
