How did sex pop up? (Introduction)

"popped up" = appeared suddenly like a jack-in-a-box

> "evolved" = appeared gradually over a long time period-We can give very good reasons for the usefulness of two sexes, more diversity in the results of reproduction, undoubtedly producing more complexity over time, and more advanced organisms. Binary fission gives the same old same old. See, I can write Darwinism. But back away from the glib just-so explanations which explain nothing.- We have no idea how DNA split into male and female chromosomes. We can talk about hermaphrodites, we can understand sperm spilled into water over eggs, etc, but at some point intromission develops. The male develops a projecting sex organ and the female provides an opening or an invagination. Here again is the same problem I have mentioned before. Two different organisms with differing sexual DNA are developing different body parts that have to fit each other and work together. Is this accomplished by simultaneous beneficial mutations in both sexes or is epigenetics at work? Is pre-planning at work?-That is why I used the term 'popped up', like the rabbit out of the hat, out of nowhere. Of course it 'evolved' over some time, but just simply saying that, does not raise the questions I have raised. If you wish, bluntly, simply accept evolution, and don't ask why or how. It is easier than puzzling over it.
