> Unlikely. You can't mate with copies of yourself unless there are already multiple copies of yourself floating around.

Asexual reproduction doesn't require copies of "yourself". Plants can self fertilize and they are some of the most complex organisms to do it and you probably know this.

Can you rephrase that statement?

I /think/ they're saying that if sexual reproduction came first, you have a pretty basic problem: where's the second individual that the first sexually reproducing entity mates with?

[Supermancho]

Sexual reproduction can involve an asexual (which would be hemaphroditic) partner.

Why would you evolve the necessary organs to sexually reproduce with your self, with no one else around?

[Supermancho]

Often times sexual organs are multipurpose. It's likely a genetic mutation that allows for sexual reproduction, as with all structural advances. I might end up with a functioning probiscus near my gamete sack and if I end up bumping into my fellow eukaryotes, that's just how it goes.
