I've been watching episodes of Cosmos, just watched episode 2 (One Voice In The Cosmic Fugue), and it serves forcibly to remind one that people who want to ban the teaching of evolution (or better still, give equal time to creationism or Intelligent Design theory) are fucking morons.
A common misconception about evolution is that it's a force that drives things, when it is actually just a word that describes a process that has already happened, and a way to (maybe) predict what may happen. It doesn't mean "survival of the fittest" or any buzzwords like that. All the process of evolution means is that patterns of genes change over time due to mutations, and particular patterns of genes propagate themselves in particular environments and other patterns of genes don't. "Fitness" for survival means nothing in any moral or qualitative sense.
Anytime someone says "if people evolved from monkeys, why are there still monkeys?" feel free to slap them around a lot, and then explain to them, using small words, that people didn't evolve from monkeys; monkeys and humans evolved from a common proto-simian ancestor.
When someone says that evolution is a theory, inform them that it is not a theory - it is a fact. It can be observed. There is physical evidence you can look at. It can be directed - poodles don't occur in nature, you know, we created poodles with artificial selection. We don't fully understand how evolution works yet, but that doesn't mean it doesn't happen. The theory of evolution is an attempt to explain the observed fact of evolution, just as the theory of gravity attempts to explain the observed fact of gravity.
The insidious thing about Intelligent Design theory (aside from the fact that it's complete bullshit) is that it tries to equate crazy voodoo religious ideas with actual science, by solemnly intoning about "objectivity" - if you don't entertain alternate theories to evolution, you aren't being objective, and therefore not practicing good science. The problem with this argument is that Intelligent Design isn't science, it's religion. Like all religious arguments, it uses circular logic - it attempts to prove its arguments using its conclusions. It can't be objectively proven. Equating unscientific religious ideas with actual hard, provable science isn't being objective, it's being stupid.
