How big would a pair of wings have to be in order to allow a human to fly? And how often would they have to flap?

While I'm sure personal human flight is much easier through fixed wings and some sort of rocket or jet propellant, however, these are not nearly as cool as a nice set of wings like a bird. I know humans are much bigger and heavier than any flying species of bird and are therefore not naturally built for flight at all. But surely this isn't beyond the capabilites of humans?

Have any intermediate forms survived to the present day, or have only final forms survived? If so, why is this?

Evolution posits that humans and chimpanzees are descended from a common ancestor. Other animals also share common ancestors or intermediate forms. Have any of these intermediate forms survived to the present day? Or have only the final forms survived? Shouldn't every final form also be an intermediate form?

loss of genetic diversity in human population

The human genoproject has demonstrated that the global population of humans can trace its roots to Africa. Given we're all linked to the same ancestory are we less genetically diverse than our African ancestors. ie over 200,000 years how much new mutation would have been added to our dna and how much would we have lost due to inbreeding in what is suspected to be small migratory groups out of africa.

Why do I live longer than a cat, but a cat lives longer than a bird, but a bird lives longer than an insect? Does life span actually matter to animals, and why do we all live for different periods of time? Does a beetle's life feel quicker, or what? Why has evolution made us like this?

Mitochondrial DNA analysis, indicates that all human race came from a single woman that existed about 140,000 years ago. Does the Neanderthal has a different ancestor? And where they came from?

Are we all blind? Last week, I helped a blind guy cross the road and while we were crossing the road I asked him if blind people can hallucinate and have dreams. He said "Of course we can". I researched this and it turns out that blind people can in fact hallucinate. This got me thinking. I was wondering if it is possible that we are all blind and we are all hallucinating the same things?

How far have primates left to evolve? I read somewhere recently that humans had all but finished evolving over the natural course of time. Whether that may be disputed or not, what I'm wondering is this: in some fifteen million years (which, according to David Attenborough's Life On Earth, is the amount of time it took us to make the transition) will primates evolve to be like us?
