PZ Myers on the human brain...
Here we go again, another creationist who doesn't understand the evolution side of the argument at all. He's criticizing the argument from bad design in a kind of backwards way.
I've never heard a Darwinist complain that the mind they use is the result of lousy design, that their mind is the result of a mindless, purposeless process and thus fundamentally untrustworthy as a reality-processor. (Would you want to buy a "word-processor" made by a random, purposeless process? Would you trust it?)
I've never heard a Darwinist complain they've been given a crappy brain never designed for abstract thought, or, indeed for thought at all. And yet, according to the self-same Darwinist, the brain is not designed for anything, just like the heart is not designed, the knee is not designed, the eye is not designed, etc. They all just popped out of the ooze, on their own, for no purpose, and if you've got problems with that, you're not very Bright™! I'll complain! I have a very bad brain for the purposes I want to use it for. It's pretty good, but prone to awkward mistakes, for deciphering behavioral cues and inferring intent in my conspecifics, which is still a useful skill, but other functions, like the ability to search out fruit and tubers, or to coordinate a hunting party, or to detect predators lying in wait, I've let slide out of a lack of utility. I'd like a brain that could hold more than half a dozen numbers at once in my head, or that wasn't prone to perceptual errors, or that could process written information a bit more efficiently than this linear, one-word-or-phrase-at-a-time parsing. I wish I had a memory that could accurately record events and scenes, rather than storing a few key hints and reconstructing the rest. I'd like a brain that was actually evolved for doing mathematics naturally, rather than requiring years of discipline and training to acquire the skill artificially.
