The Infinitely Prolonged
I agree with you on one point: Chance mutations could not possibly have evolved a bacteria into, for example, Barack Obama.I'll grant that natural selection accounts for the bacteria becoming PCN resistant. But I am certainly not entitled to jump from there to the conclusion that given the penicillin resistance example, Obama, the whale and the sunflower are linked to a common ancestor through the process of selection pressure squeezing chance mutations in the direction of these three very different biological outcomes.
But, you must understand: Chance has nothing much to do with evolution! Bacteria can evolve, over looong periods of time, into people.. because they are driven by natural non-random selection pressures.
If you read Richard Dawkins' books carefully, this should have been made clear to you. At no point does Dawkins claim chance has anything to do with this. His books are all about breaking down the non-random selection pressures that lead to changes in survival strategies, etc.
Science and religion are going to butt-heads on these sorts of things, because science sees this distinction as very important. Whereas the religious are just fine with their strawmans and mischaracterizations.
How evolution works has a strong bearing on how, for example, morality works. Not getting the facts right could lead to profoundly insane conclusions.
