With the continuous advancement of social consciousness and science, human beings have once again ushered in evolution, no longer the simple sexual reproduction in history.
Women with a sense of aggression and struggle gradually lose their reproductive function, and instead gain the ability to impregnate others - female Alhpa;
Gentle, family-oriented men, with the ability to give birth to life - male Omega;
In the process of evolution, more and more human beings seem to be no longer willing to bear the responsibility of transmitting life from their consciousness, and their fertility ability gradually weakens. If it were not for the occasional miracle of life fire, humans almost thought that their fertility ability had completely disappeared-Beta
Humanity has since differentiated into five or six genders.
It is probably a compensatory effect in evolution. Along with this gender transformation, human hormones are no longer the things that affect human love emotions in the ancient world. This thing changes with human fertility, that is, the glands of A and O are abnormally developed, and B has only a very small chance in his life to activate this gland, and thus have the possibility of conception or fertilization, just like the appendix of old humans.
