you like patently false statements, don't you?

as you can guess--wrong. the ToE is dependent on getting your genes passed on. your statement discludes (i may have made that up?) all the asexually reproducing organims. and if you don't have children, but you're sister or brother does, what do you generally do? you help your sister/brother with raising them--they do have a good chunck of the same genes you do--they are family.
In my own personal experience:I have an aunt, mom's sister, who couldn't have children. She has spent more money on my brother and cousins (mom's side of family) and me than any other aunt/uncle. She has also done more for us. If she had kids of her own, she wouldn't have. of course, this one example won't establish causality, but it's a start. someone here probably has a study to link for this.
All a man's knowledge comes from his experiences
