From what I understand, homosexuality among humans throughout history (to the best of our knowledge) remains at 10%. Why is this? Are enough homosexuals propogating through heterosexual means to keep the genetic causes for homosexuality in the population? [more inside]

Evolutionary Biologists: A friend and I were walking through the woods, saw a deer and started pondering our ability to survive with primitive tools. We couldn't get within 40 meters of the deer before it took off. I couldn't see myself making a missile weapon to kill it at that range even with years of experience. My friend asserted that evolutionary pressures have produced deer that are quite a bit more skittish than the deer our distant ancestors had to hunt... [more inside]

I was introduced to a fantastic image linked here on MetaFilter years ago. The image was a standard riff on the ascent of man motif, with the final Homo Sapiens looking up to the stars, and a message along the lines of "At NASA, we know where our future lies." If my memory stills works, it was originally a poster. Can anyone help me locate this? Apparently, my google-fu hasn't evolved since then, and constant browsing of NASA's image archive has been fruitless.
does the theory of evolution have an explanation for inter-species mimicry? [more inside]
Inspired by this question, does anyone remember an illustrated, sci-fi book that came out about 15-20 years ago, which consisted mostly of possible forms that human evolution would take, and full-colour illustrations of what these future humans would look like? [more inside]
I am trying to find articles online which delve into the origins of naming human offspring and whether or not other species have audible monickers as well. [more inside]
"Daddy, where do we come from? How did people get here?". I love my inquisitive little guy! Can anyone point me to a good illustrated resource on evolutionary biology for little kids?
Are there really such things as "scars on chromosomes" and "X vs. Y" 'wars' between the male- and female-determining genes? [more inside]

Is there an evolutionary drive towards more complex organisms? Douglas Rushkoff believes there is: ”It appears obvious, yet absolutely unconfirmable, that matter is groping towards complexity.” [link] I've taken it for granted, but is it really true? What do we know about this?
its my understanding that stuff generally feels smells tastes or looks good because it benefits our survival. Fats and sugars have energy. Sex continues the species. Good interior design makes you feel safe - etc etc.
So why do flowers 'smell good'?

My father, though a very iintelligent and respected lawyer, says he often has trouble accepting the idea of macro-evolution, because he says to him the idea is too vast to take in. Can anyone suggest some books on the topic that can explain evolution better than my feeble attempts?

How did we evolve separate genders? I assume it happened pretty early on, since most animals have a male and female, but wouldn't it have had to happen to lots of things at once for it to actually work?
This might be an easy one for you all. My former roommate was telling me about this book that sounded really interesting but I cant think of the title for the life of me. All i remember is that the book contained a conversation between an ape and a human being about evolution or something like that. Ring any bells?
I've always kind of wondered this. I don't know if it's a metaphysical question, an evolution question or just a childish question, but why exactly are there fruit trees? Has anyone seen a definitive answer to this. Does it seem weird that a tree would produce fruit just so animals can come and steal it? Do fruit trees benefit from producing fruit (like I understand how the leaves come into play)? I feel like a little kid asking this, but does anyone got an answer?
IS there any evolutionary advantages to monogamy; non-violence; vegetarianism; religion?
It's easy to tell when a species has gone extinct. How do you tell when a new species has evolved? Are there any criteria besides not being able to mate with the former species?
How do evolutionary changes occur in biology? Is there some sort of "intelligence" that helps a species adapt, or does a species have to wait for a random mutation to occur that just happens to confer an advantage (a mutation that might never even happen)? For instance, how do bacteria become resistant? And are there different theories on evolutionary changes?
Is the idea that "we evolved because we did" different from the weak anthropomorphic principle?
