I have a questions about evolution myself (also not doubting it's truth)
How did we evolve from an organism that reproduces by asexual reproduction, to an organism that reproduces with sexual reproduction? Wouldn't it mean that at the same time in the same place, two organism mutate in such a way that they can mate with each other?
And another simpler question that I'm pretty sure i know the answer to, where do tree's fit into evolution? I'm assuming at the very beginning.
It's like asking, if Americans came from europe, why are there still Europeans? Simple, there were Europeans, now there are both Americans and modern Europeans.
Evolution is not goal orientated, one species A does not actively seek to evolve into another species B until all of A has turned into B. And rarely is evolution about one species turning into another, but diverging from a common ancestor.
Like NoNameC68 says, we did not evolve from modern apes but rather have evolved from a common ancestor, later than other animals. Although depending on classification we are still a species of apes. We don't evolve from our cousins, that just doesn't make sense, that's like asking if my cousin gave birth to me, but we do share grandparents.
There are of course species alive today that seem to have evolved very little for some time, but this does not disprove evolution at all. It's a studied part of evolution called punctuated equilibrium which you can read up if you want.
I don't claim to be an expert on the subject by any means, most of this should be taught in schools and is easily available online. If you don't understand how something is, look it up. Just because you don't understand how something works doesn't even hint that the theory is wrong.
human and other primates evolved from an older species of monkey. Not modern day monkeys mind you. This might bring you to ask why are there still monkeys then? Think of it this way if I took a large lump of clay split that clay into two piles and made a statue out of one of the piles. Would it then make sense to ask "If you made a statue out of clay why is there still a pile of clay?" With the monkeys they got split up into groups. With one group undergoing far more changes due to different environmental pressures than the other. This resulted in one group eventually losing it's tail, growing a larger brain becoming less hairy and so on. While the other group remained in the niche it was in and didn't need to change all that much.
If you would like to learn more about the theory please check out my profile or ask away.

I don't really see any difficulties in imagining that two multicelular organisms each releasing a copy of one of their cells which do a mixing of genes being at an advantage over one that simply doesn't mingle. Evolving two different types of gametes would then come next, producing hermaphrodites.
Although it would interest me if someone could go into detail on how two different sexes comes about. Seems like two branches of evolution occuring simultaneusly for each species, one for each sex.

Here's a video that can answer your question. Also keep in mind evolution occurs in groups not individuals. The Origin of Sexual Reproduction

No not at the beginning the came onto the scene around the late Devonian period some 416-359 million years ago.
I actually found this video off your profile already, which also answered my question about multi cellular organisms.

I find it difficult to see that this mutation in organism came to be in two different organisms in the same time and place, but the links Mage provided (still in the middle of them) seem to answer it.
