Mental retardation is seldom genetic.
Mental retardation is overwhelmingly caused by fragile X syndrome or down syndrome, which are 100% genetic. They make up the majority of the developmentally delayed community.

Haven't we proven enough of our theories about this world that we know for certain things are stable to a known degree?
Not to be contrarian, but we haven't proven any of our theories at all.
First, you do not know what is occurring in every place in the universe. No number of experiments will ever prove a theory to be true because you cannot perform the test at every conceivable place in the universe. This is why Francis Bacon stated that the proper scientific method should be falsification. You only have to find one place where a theory comes up short to prove it wrong, but time constraints say that you can never prove that it is right. This is what modern science is based upon.
More importantly to his post, however, is the fact that we have no deductive reason to assume that the future will replicate the past. The GP says
Pointing out that it's worked before is just begging the question
He is referring to the problem of induction http://en.wikipedia.org/wiki/Problem_of_induction
This is not "fancy footwork," it is a many centuries old philosophical problem brought up by David Hume. You cannot state "X happened in the past, therefor it will happen in the future" without using "X happened in the past" as your reason for believing "X will continue to happen."
Essentially, you cannot prove induction correct without being inductive. "The ice I've touched has been cold, therefor all ice is cold" is not deductive reasoning.
This is, for all intents and purposes, a genuine criticism of the scientific method. "All ice I've ever touched is cold" may be true, but "All ice is cold" is completely false. http://arstechnica.com/science/news/2007/03/turing-water-into-very-hot-ice-very-very-quickly.ars http://uk.reuters.com/article/idUKN1621607620070516
This is the sort of thinking that science employs, however. Now, his point is not that science is not useful, nor is it that science is wrong. He is simply stating that inductive thinking is programmed into us, and that there is no good deductive logic which led us to it. You see neither causality nor time, these concepts exist inside of you -- i.e. Science is a byproduct of being an ape, not a byproduct of logic itself.
