The point is that this began among the bacteria two billion years ago. By the time of the Cambrian and modern. larger critters two sexes was simply how it was done.
. . . The biology professors, to a man, or woman, scratch their heads to the point of bleeding concerning an intractable problem with mammalian sex: meiosis and polar body.
They explain that there appears to be no way under the sun that meiotic sex could have arisen naturally, since for one, it's irreducibly complex, and two, there appears to be no possible reason for its very existence.
When the great Jewish sages find a great and intractable exegetical problem in the DNA of the cosmos, the Torah-text, they realize it hides the greatest of secrets.
Meiotic sex is that in spades, since, as I pointed out earlier in the thread, sex was a trade made with the angel of death itself.
Organisms allowed the serpent of death (the serpentine organ) to enter the original, non-gendered body (which is the form we now call "female," though before the male it was singular and non-gendered flesh), in a trade-off for allowing the the bride and groom of gendered-sex to have some modicum of authority over evolutionary adaptation.
Ancient religions sanctify and glorify the chuppah, the wedding rituals, understanding mythologically speaking precisely what is being said. Marriage, and gendered-sex is a trade with the serpent of death whereby he enters into the very biology of the biosphere, in trade for bride and groom sharing in nature's power over selection, life, and death.
Meiotic sex is the unfathomable glory revealed in the newest version of the Bible. It reveals that by throwing off the senescent, death-infected chromosomes, preparation is being made for the biggest surprise death could ever get: it was tricked in the trade-off that let it into biology through two-gendered sex.
Meiotic sex, by throwing off the twenty-three chromosomes associated with semen, not only makes the semen the sole carrier of death's authority (senescence and death) but it prepares for the end of the reign of death that Professor Elliot R. Wolfson calls "the reign of the phallus."
By cleansing the ovum prior to re-contamination at the point of conception, the seed of the woman is prepared for a virgin birth whose son will not be subject to the trade made with death in the first place, the garden of immortality.
Death is dumb. It's been tricked. It was on the wrong side of the trade-off between its sole authority over environmental death versus the organism's ability to skirt that death.
Through the virgin birth, death has lost it all. Living organism don't intend to merely return to some form of immortality that leaves the environment still able to destroy life. Through the virgin birth, life is now set to eliminate the environment's ability to bring death to even immortal organisms.
The virgin birth is the myth of how mind tricked death so that all who trade this life, and this mindless realm, for Christ Jesus, will not, per Moses and the Law, return to some realm of mere immortality still subject to death. On the contrary, those who are in-Christ, through virgin birth, being born-again, without the serpentine flesh, will, as Jesus said, never die, ever; will never taste death.
