i want to see loc post in here
Your wish is my command...
Basicly what Sylverfish says, is correct, only I didn't know it was done in those terms.
What I basicly know is that by definition everyone starts out as female, Penis and Testes, excuse the lingua here, only develop at a later stage, its the same as why men have nipples, tis the same cause, only with men, nipples are redundant "organs" so they don't develop as much as with women, also, the male breed misses the organs for synthesizing "Maternal milk" out of bodical fluids, the men have them alright, but theyve shriveled by the time we reach age five or so, as is with all Organs that have outlived their function, only some organs don't shrivel as fast as other, the human Tailbone, a non-gender specific organ, will take a few more thousand years to fade away, the organ has reached redundancy a few million years ago, with the introducion of Homo Erectus iirc, but I think I am happily strolling away from the point here.
Basically what defines male and Female are XX and XY, as already stated before XX for women, and XY for men.
Or in common playground talk, A Penis and a Vagina (again, sorry for the explicitives)
well thats my drivel for the day, ill leave it up to the pro's to consider if its not total hogwash, and as always, if not correct, please feel free to correct the incorrectives.
