I'm not anti-evolution. I'm just wondering, how can a species evolve from asexuality to sexuality? Would it have to go through a period where it could do both?

And what came first, the ability to have sex to have kids, or the pleasure the comes from having sex? Neither would help much without the other.

I can accept that my grandfather was a monkey, but there's no way he was some shrub. I don't need science to tell me that. What is wrong with you people? Just because I had an ancestor in common with G.W. Bush doesn't make you evolutionists right.

How does a white blood cell know where to go and what to attack? How does a RNA know that it has to deliver a message to a ribosome? How do antibodies know what to attack? How does a virus know where to go? etc...
How can it do all these things without a brain or something?
I'm very curious!

Yet they do function. As a eurkaryotic cells develop, they begin to compartmentalize and form organells, which allow them to perform specialized fuctions. what are 2 cellular structures or organells that provide unique biological functions for the cell and describe them
