>While it's possible, hypothetically, that flouridation isn't the cause, doesn't the correlation still bother you?

No, why should it? There's a correlation between being in New York City and being killed in a terrorist attack... that doesn't stop me from visiting almost once a month.

Just because two things happen to coincide does not imply one is the cause of the other. Again - this is why I don't approve of "research" built purely on statistical observation.

Wrong. Evolution is a selective process. The simplest adaptation that is most effective is always the best. Once a creature evolves a working eye, it won't need another until it becomes more advantageous. We have binocular vision to judge distance. No creature would need a third eye. We have fingers to grip branches, we have noses to detect the chemical composition of the air, and we taste to detect the chemical composition of food mater so as to determine if it is poisonous(incidentally this is why we see colour as well). Every part of us(including our brains) is the result of a random mutation that proved more effective in our environment. Every endo-skeletal animal on the planet has four limbs because they didn't need more. The specific parts our brains are larger than the the lesser beast on our planet, because they needed to be. To judge colour we needed advanced visual centers, when we left the trees, we developed enlarged sections of the brain to support language because because we need extra eyes to watch for predators.(With binocular visions we loose the ability to watch behind us and our sides like slower beast. I.E. cows)

Aliens(if they are capable of space flight) will be startlingly similar to us, because they would have to have evolved along similar lines to posses the manual dexterity to craft tools, and the increased mental capacity to understand the abstract. They will likely breath air similar to ours and eat food similar to ours.(have you ever tried to design advanced computer systems in a completely submerge environment?)
