A buzzword that creationists use to refer to the theory of
evolution. They use this word to try to equate the theory of
evolution with ideologies like
communism and fascism.
Such a tactic is dishonest. The theory of
evolution is not an ideology. Ideologies are PROSCRIPTIVE--they make value judgments and say what should and shouldn't be done. The theory of evolution, like all other scientific theories like gravity, relativity, etc., is DESCRIPTIVE--it describes and explains facts. Such theories are testable by analyzing them to see what the predictions that they make, and then seeing if those predictions match the facts.
For example, applying the theory of relativity predicts where the stars will be. We look at our hubble telescope and see that lo and behold, the stars are indeed where the theory predicts them to be!
The theory of evolution predicts that the evidence will show that humans and chimpanzees are closely related. We look at human chromosome 2, and see that it's virtually totally analagous to
two chimp chromosomes, and lo and behold, human chromosome 2 has a fusion site with telomeres in the middle of the chromosome! (Imagine taking the 2
chimp chromosomes and "scotch-taping" them together--that's what human chromosome 2 looks like).
