Genetic variation is a good thing, because you would look like me and I don't think you want that =). What I'm asking is why or how you go from asexual reproduction to sexual reproduction. That's a pretty big jump. What I believe evolution is saying is that a cell (or bacteria) mutated to form a male part and somehow kept that genetic mutation (let's say for a thousand years). Later a second bacteria mutated to form a female part (let's say another thousand years). Then somehow those two understood the male and female parts were used for reproduction. And then, the genetic mutations continued to form something as complex as a flower or mouse. And please remember that this is a trial and error process of getting ALL the genetic material aligned properly. So, there is no organization to this process. This is a brief outline of thought. There is much, much more that needs to happen! I've been stuck on this question of sexual reproduction for a while and I think I would believe evolution more if there wasn't such a deviation from asexual to sexual. The more I think about the details and intricacy of this process, the harder it is for me to believe in evolution.
