A lesson on speaking out in ignorance

As part of his Easter homily, Pope Benedict XVI invoked evolution in describing Christ’s resurrection:  If we may borrow the language of the theory of evolution, it is the greatest ‘mutation,’ absolutely the most crucial leap into a totally new dimension that there has ever been in the long history…

Darwin’s “theory of evolution” isn’t evolution; it’s natural selection

I can always tell when an opponent of Darwin's "theory of evolution" has never read Darwin, because they try to claim that Darwin's "theory of evolution" means that "evolution is a theory." Unfortunately for them, the phrase "Darwin's theory of evolution" does not mean evolution was Darwin's theory.  Scientists recognized evolution long…

Why does “irreducible complexity” sometimes demand a creator and sometimes not?

So here's my question:  creationists (a subset of Fundamentalist Christians) claim that life on earth is too "irreducibly complex" to have arisen spontaneously, without an "intelligent designer," so how do they explain the existence of God, who is, presumably, infinitely more "complex" than any life on earth?  Was God designed by…

The importance of pop quizzes

You’ve just noticed several people carrying signs that say “Down with Ice Cream.”   You approach them to ask what is so bad about ice cream.  After listening to them for a few minutes, it becomes clear to you that there is a misunderstanding.  To them, the phrase “ice cream” actually means kicking dogs.  They are against kicking dogs. 

“Oh, you mean that you’re against kicking dogs?” you ask.

“Down with ice cream!” they nod.

It’s impossible to have a meaningful conversation without a common understanding of the words being used.  “Evolution” is a good example.   When I hear someone speaking disparagingly about evolution I can trigger the following exchange:

Q:  What’s so bad about evolution?

A: It’s just a theory (#1) that says that everything here is just an accident (#2) and that people came from monkeys (#3).

Zero for three, every time.  In short, most people who “oppose” evolution are against something other than the scientific theory of evolution.  Further, most anti-evolutionists I’ve encountered don’t know what scientists say about evolution and don’t care [Good places to learn what scientists think would be here and here.]

The irony is that most people who oppose evolution are not opposed to any of the major facts upon which evolution is based (e.g., that random mutations occur, that some of these mutations make organisms more likely to survive long enough to bear offspring, or that a parent’s traits tend to be passed on to its children).  In fact, opponents don’t usually …
