One frequent claim is that biologists believe evolution happens by random chance. They don't. They think that species adapt through a process called natural selection. For example, the idea that a complex structure could arise spontaneously by chance is equivalent to throwing 100 coins in the air and expecting them all to come up heads. There is only about one chance in 10^30 of this happening. Why would creationists say that any scientist could possibly believe in something so preposterous? Instead, biologists think like this: Throw 100 coins as before. Now pick up the tails (usually about 50) and throw them again. Pick up the remaining tails and throw again. In less than 10 throws, all 100 coins will come up heads! All it took was random chance, selection, and repetition. So randomness is not what drives evolution in a certain direction (like, towards more complexity); it is NATURAL SELECTION that's in the driver's seat.

Dear Indecisive, "Get your facts straight before you criticize." Couldn't have put it better.

Dear chris_muriel007, I helped create an FDA-approved diagnostic test that scans HIV genes (protease and RT) for mutations that result in anti-viral drug resistance. Yes, mindless objects (very tiny ones) do undergo natural selection. Just because you've never seen a thing doesn't mean it's not there. Now look! I'm preaching to a Believer!

OK, I ask a perfectly legitimate question, and even gave an example. Not one responder so far has EVEN ATTEMPTED to answer the question. Yet creationists are still telling biologists that they think we all got here "by chance". Please answer the question!
