"why sex has been preserved and propagated by evolution, it brings us to the next enigma as to how it is determined. In humans the presence of a single gene called SRY and located on the Y Chromosome determines the development and thus birth of a male child. Those with two X chromosomes and no Y develop as females. Those with an XY combination develop as males. A non-functioning SRY gene on the Y chromosome leads to development as a female with a blind vagina and an absent uterus. Thus the natural tendency of a human fetus is to develop as a female unless interfered and stopped by the product of the SRY gene on the Y chromosome.


It gets even stranger in a fish called the blue-headed wrasse, where the normal social life is organized like the Mormons, with a single large dominant male and a harem of females. Surprisingly, if the male dies by natural causes or predation, the largest female in the harem swiftly changes into a male and captures the harem. individuals begin life as either male or female, but females can change sex later in life and function as males. "

So was the human female ever capable of this "miracle" and whether or not some "cosmic program" or ????? prevented this - AND 4 HOW LONG? if the human male becomes gerund in 100,000 years as predicted by geneticists-IF EVOLUTION HAS ANY MEANING Y DID HUMAN MALE EVOLVE (From Female)?.
