Early embryology; chromosome count correction! (Introduction)

I'd love some Darwinist explain this phenomenon to me. How did evolution add this protective mechanism to embryoes that are in the 3 to 5 day range of development? How does natural selection operate in this situation?

> Cells have had an ability for self-repair-->Not everyone who gets sunburned develops cancer... I don't see how this challenges NS.-What caused those cells to develop self-repair? These are blast cells in very early development. They are competing against their own death. I'm imagining this occuring in early evolution, as sex first appeared. This is epigenetics, not NS. Epigenetics had to be present very early as a self-defense process when organisms mated. NS is an after-thought, if you wish to use it by recognizing the organism can survive. Cells without self-defense will not.
