I read your 2010 post about Jewish genetics. You made reference to Heroditus, Colchis and circumcism and Egypt. It is believed the one Egyptian ruler about 2,000 bc extended his reach as far as Colchis on the east end of the Black Sea. Soldiers and perhaps Egyptian merchants and settlers were stationed there and it has been reported that people there sometimes have black curly hair suggesting some African influence (interesting genetic study project). I believe the ruler was Sesostris II.
A related tidbit of information. Colchicine is a medicine (for gout?) taken from a kind of crocus found in that area. There is a picture from Santorini in ruins preserved by volcanic ash (Akrotiri?) which shows a Greek goddess surrounding with crocuses. Perhaps these were the medicinal crocuses from Colchis? That might have been around 1600 bc. The question marks are because I am too tired/lazy? to Google the facts, just using memory.
