I buy Darwin and his evolutionary theories 100 %. One thing that puzzles me is how do genes for homosexuality get passed on, since presumably homos engage primarily in non reproductive sex. What selective pressure could their be to make this non reproductive behavior persist and how is it passed on? Of course, Im assuming that in many cases, genes play a part in a persons being gay or straight.

For the upcoming science fair, I'm toying with the idea of such an experiment.
How do you think I could compare the bacteria in food samples? Is there some kind of solution that I could use with a food sample that could determine the level of contamination?
Oh, and please keep this relatively simple. I'm in the eight grade.
