In Reference to the "Sexes Without Sex" Post

The evolutionary explanation of where male and female must have come from, has angered some believers in the theory. Calling me an idiot, a rat, a dummy, stupid, a hypocrite, an imbecile, dense, brainless, a dimwit, an uneducated fool, a liar, or a combination of these is okay. However, names with sexual connotations will be deleted.

Some of you have written long and sincere comments, and then ended with a remark I have to delete, when I would prefer to let it through.

It would strengthen the evolution case (instead of resorting to name-calling) to instead explain what Darwin did believe about the origin of male and female. Enlighten me.

Dimensio said, "In fact, distinct gender emerged as a result of organisms being able to reproduce through the sharing of genetic information in reproduction. Initial 'sexual' reproduction of this nature was essentially gender-neutral, as there was no 'male' or 'female' assignment because any given organism could share or receive compatible genetic information from another organism of the same species. Gender differentiation emerged as a result of specialization of this ability."

Dimensio...Can you please explain to me how you know this to be true?
