Ok, lets just say natural selection makes apes become people. But natural selection doesn't make all things exactly alike. That's why it's NATURAL SELECTION. But if you look at a human you see that we ALL have the same body parts. Maybe not the same skin or look but the SAME body parts. How does natural selection turn all the monkeys into the SAME thing? Can it think? Is natural selection some how magic? Does it have GOD like abilities to change a whole tribe of one animal into a whole tribe of another. Why didn't some of use get three arms and one leg. Why didn't some of us get three eyes instead of two??? Funny how natural selection somehow made us all the same....almost like we were created..... NAW, That would make TOO MUCH SENSE!

People nowadays seem to be attributing homosexuals to have a gene in them that makes them prefer the same gender. The same people are strong believers in evolution, which strikes me an oddity. My question is, wouldn't the result of evolution be completely heterosexual genes to allow fruitful reproduction? Are homosexual genes and evolution compatible? Is one right, the other wrong? Will evolution outgrow homosexuality and eventually leave everyone to be heterosexual?

Not trying to stir any controversy - just an honest question wanting a legitimate answer.
