May be we should use different perspective, How about a scientific equation that change everything(from -MAN IS THE EXTENSION OF WOMAN)But look at the man. He is something more. He is X and Y. That means, he is essentially an ‘X ’plus something extra. What do I mean by that! Man is already a woman that is ‘X’, plus something extra. Does that mean first step towards manhood is womanhood? Now let’s talk in mathematical language. Here is the equation, Man = 22 autosomes + X + Y Woman= 22 autosomes + X + X= 22 autsomes + X (by logic not by mathematics). . . Man= (22 autosomes + X) + Y= Woman + Y (by mathematics, simply) So man is everything that woman is, plus something extra. Now the extra thing is not qualitatively different, but quantitatively. Hence Y here must be somewhat like X + 1, X+2 or X+ 3 or something like that. It would be ultimately proven that woman can potentially grow into man. Similarly man can reduce to woman, if he loses some part of ‘Y’.
