No Maciamo there wasn't Hindu-style segregation in Greece (or Greek Macedonia) you claim to be a scientist and you don't know that?
First of all, I don't see why being a scientist confers knowledge about history. Second, even historians cannot know everything about history. Third, I never "claimed" to be a scientist. This appellation doesn't mean anything to me. There are all sorts of "scientists". There are hundreds of specialities. Then a scientist could be either a researcher or a practician (like a doctor) or just someone who studied a scientific subject at university but doesn't necessarily work in a scientific field. These are all completely different things. That's why I would never refer to myself simply as a "scientist". Too vague. Meaningless.
Now to the point debated.
How could you possibly know that no Hindu-style apartheid happened in Greece following the PIE invasions ? Apart from archaeology (pots, weapons, graves), nothing is known about Greek society when the PIE invaded Europe from the steppes (a long process of successive waves of migrations that last from circa 3500 to 1500 BCE) We do know about the Mycenaeans who were the first Greek rulers who spoke an Indo-European language and had arts and customs clearly linked to the Pontic steppes (axes, fortified palace, underground burial chambers like the kurgan, etc). The Mycenaeans did practice a sort of apartheid between the elite/nobility and the the da-mo (demos, populace), i.e. the craftsmen, farmers, and merchants. This was followed by a long dark age in Greek history (1200-800 BCE) about which virtually nothing is known of the way people lived. The most likely scenario in my eyes is that the Indo-Europeans behaved similarly in all the regions they conquered. The similitude in culture, religion, language and lifestyle are so striking between Bronze-age Celts, Germans, Slavs and Hindus, over 2000 years after they split from each others, that it is reasonable to suppose that the organisation of society was roughly the same too. I have little doubts about the Mycenaeans, and am convinced that the genetic testing of Mycenaean graves will confirm that their elite remained predominantly Indo-European, not indigenous Greek. It is however much harder to estimate whether this elitist segregation continued through the Dark Ages or not, and if so whether it lasted until the time of Alexander.
Your reply is typical of people who cannot read properly (quite a few people here it seems). I never claimed to know. I just wrote:
"
If the Macedonian elite descended from the Macedonian branch of the Indo-Europeans,
and ["if" implied] the elite kept a strict apartheid with the conquered population until the time of Alexander (possible considering that Hindus have managed to do it for the last 4500 years),
then the most likely haplogroups for Alexander the Great and other ancient Macedonian nobility was R1a1a, R1b1b2 or G2a3b1."
There are
two strict conditions to my hypothesis:
1) the Macedonian elite
must be descended from the Indo-Europeans
2) this Macedonian elite
must have kept a Hindu-style apartheid for thousands of years
If both conditions are met, then (and only then) there is a very high probability (but never 100%) that Alexander belonged to R1a1a, R1b1b2 or G2a3b1. I know that is a lot of if's, which makes it only a remote hypothesis. I never claimed otherwise. There are only people here who can't read (you and Sprinkles) and mistakenly assume that I have reached an irrevocable conclusion, when I have just presented a mere conditional hypothesis.
And by the way nobility does not come from a straight line for thousand of years, there are countless examples of Kings in ancient Greece who came from abroad and substituted previous Kings of native origin. You seem to think that ancient Greek kings belonged to what you call Indo-European rulling class but this is absurd...Alexander claimed descend from Temenus of Argos who belonged to the Heraclidae (they considered themselves descendants of Hercules who was a Danaan).
Because descending from Hercules, a mythological figure, is less absurd in your eyes ?!
