It's not a bad way of putting it, because I wasn't referring to natural selection. I didn't disagree with you, I simply noted another fact that many people forget. I know this won't persuade you into "believing" me, but I'm a biology student and many of my professors cannot stress the factor of chance enough, because it's something that many people tend to forget, when they're teaching the theory of evolution. This does not contradict the mechanisms of natural selection, it adds an aspect to it, that cannot be predicted.

Random mutations, change of environment and natural selection are factors of evolution, but so is chance. As I said, chance is another important factor. There may be organisms that are perfectly adapted to their environment, but they still wouldn't survive a volcanic eruption or a meteor hitting the earth. And chance in the form of natural 'catastrophes' has contributed to the biodiversity that we know today.
Natural selection does not lead towards the strong surviving, but the best adapted surviving.
