Prove or Disprove

Short one as not much to rant about today, however some general web surfing has made me think about a few issues in science related to Evolution / Creationism.

The scientific method is well established and is certainly the “generally accepted” way of defining what is scientific and what isn’t. This method, not some half baked 2000 year old text which has been re-written more times than I can count, provides the yardstick against which all science is measured – be it Evolution, Relativity, Electromagnetism, anything. Without it, well, it’s back to the dark ages.

The crux of the method is the ability to make testable predictions and carry out proper experiments which can falsify the theory. You dont actually have to prove the theory wrong for it to be scientific (although this is a common misconception of the term) but you need to be able to construct an experiment which could prove the theory wrong. This is important so make a note of it.

Now, on to the wonders of creationism. Most, if not all, creationist propaganda carries the sole message that “Evolution is Wrong.” If you do a YouTube, Google or (especially) a MySpace search you come across all manner of idiocy and madness about the topic. People saying “evolution is wrong because … [insert nonsense].” Things range from the “missing link” oddity to crazy arguments like irreducible complexity. The main thing they all have in common is the nonsense and bad science which tends to back them.

The important thing, in the context of this post anyway, is the issue about disproving evolution.

First off, the fact that the lunatics (ID, YEC et al) are capable of coming up with a possible experimental circumstance which could disprove evolution reinforces the fact that evolution is scientific. Scientific does not mean true or correct. Newtonian Gravity was a scientific theory which turned out to be incorrect. This is part of the way science works. A scientific fact has more caveats than the average person would ever think of applying to something “factual.”

Secondly, and possibly more importantly, even if the lunatics did manage to disprove the theory of evolution, that does not mean Creationism takes a default win. That is not how science works. A flaw in general relativity (eg, interactions on the quantum scale) does not mean Newtonian Gravity is correct – or to be a more accurate analogy, a flaw in GR does not mean gravity is caused by bananas. Finding something in a theory which is wrong is the “Holy Grail” (all puns intended) of science. It means people get to advocate new Scientific theories (sorry, creationists, you dont count). People get Nobel prizes. People get huge amounts of funding. (and so on).

Intelligent Design / Creationism / whatever, is not scientific. It really isn’t. Saying “God Did It” is not science – even changing God to something you think will slip under the radar still does not make it science. If anything it is the end of science. It blocks further investigation because if anything is unknown or fails to meet the predictions you can just say “the creator wanted it that way and who are we to second guess the all-mighty one?”

Falsifying evolution would be a good thing, but it certainly would not mean creationism was the correct science. The theory of evolution is scientific. It almost certainly is not the endstate for our understanding of life and it makes no predictions about how life started, but it is a valid, solid, theory. Just like gravity. I am not going to even think of getting worked up about the “it’s just a theory” crap…
