And in the Did You Know category: Did you know the Bible was written by mere mortal men who, according to their society, maintained a purely male dominated society relegating women to a second class status? The exception to this was with the Old Testament period wherein the Judaic society held women, in many respects, as the rulers of the tribe. This, in fact, holds true even unto today where the heritage of the bloodline follows the woman's line.
And, did you know, back in the 1980's (and recently released again pretending to be new info) there was one specific gene isolated and found in everyone? EVERYONE regardless of who or where they lived, were born, or what their native ancestry might be. This gene is passed down through the female only and was designated the Eve Gene. So that old saw about "we are all brothers" is actually true!
