Urinating from sex organs

Why do humans and animals(?) urinate from their sex organs? Are these two bodily functions in some way related? Are their examples of animals that pee & have sex with parts of their bodies that are spaced far apart? [more inside]

How did sexual reproduction evolve?

How did we evolve separate genders? I assume it happened pretty early on, since most animals have a male and female, but wouldn't it have had to happen to lots of things at once for it to actually work?
