I can envision observations and experiments that would disprove any evolutionary theory I know.

Skepticism's bad rap arises from the impression that, however necessary the activity, it can only be regarded as a negative removal of false claims. Not so... Proper debunking is done in the interest of an alternate model of explanation, not as a nihilistic exercise. The alternate model is rationality itself, tied to moral decency--the most powerful joint instrument for good that our planet has ever known.

You put three facts together - that all organisms produce more offspring that can survive, that there's variation among organisms, and that at least some of that variation is inherited - and the syllogistic inference is natural selection.

People may believe correct things for the damndest and weirdest of wrong reasons.

I'm not a great deductive thinker, but I will admit to having competence in a very wide range of things - not being afraid to try to write about baseball, choral music and dinosaurs in the same week and see connections among them.

But we all recognise the primary foible of frail humanity - our propensity for embracing hope and shunning logic, our tendency to believe what we desire rather than what we observe.
