Ooh, you were a science teacher! Gosh, I thought about this post for a while and it just makes me want to finish my WIPs. I have so many human-Cylon hybrids in my WIPs it's a shame. I've been fascinated with the idea for years. Remember I once had started an essay on science fiction's fascination with an alien/human hybrid? That WIP is on permanent hiatus now, but I think the fact that I've seen humans uniting and attempting to breed with aliens in so many TV shows and movies that it totally affects my reading of BSG. Someday I will get my totally non-human aliens. But your points are well taken. Humans made them and they used human bodies to 'evolve'. And they have succeed in mating so they are human-like. I just don't like to think that all aliens' natural end point is to become human because that's normal or good or right. I believe in each species' intrinsic right to simply be whoever they are without being judged by our standards.

I don't know if the Cylons are human or not. I honestly think they are still evolving. Humans are still evolving. Who knows where it might end? I also think that whenever two closely related human species tried to exist on Earth, one eventually died out. I'm talking about prehistoric humanoids. Even though they could probably interbreed, I don't know, we sorta always ended up with one species at a time, I think.

I need to finish my WIPs! You have woken me up to do that! This is why I like conversations with you. :-)
