I’ve never found the ID arguments for the design of biological organisms all that compelling for a number of reasons. The dubious math, the fallacious arguments, the disingenuous bait and switch to Christian apologetics, and so forth. But even beyond that, there was something about objects in nature – organisms themselves – that just don’t seem designed to me. There is something different about them compared to man-made objects, but for the longest time I just could not put my finger on what I felt the difference was. And then it hit me last night: replaceable parts.
All man-made objects – every single one – is either designed specifically to be discarded or has components that are designed specifically to be replaced. Why? Because tool users learn really quick that tools and/or certain parts of tools wear out. So as designers, we <i>anticipate the need for maintenance</i>.
No such anticipation or planning for maintenance can be found in nature. None. If something breaks in an organism, either that organism learns to live without it or it dies. Or, in the case of humans, that part gets replaced by human designed or human configured replacements (as in my case). But even in the later case, humans have to create a work-around, because biological parts actual <i>resist</i> being replaced. You can’t just replace human parts with other human parts willy-nilly. In most cases, the new parts just won’t work, or worse, they’ll be rejected by the body’s immune system. But of particular note, there’s no surplus of replacement parts anywhere; no storage unit somewhere with a bunch of eyes or hearts or toes or hair or kidneys or…anything. Not even bark or leaves or antennae or scales. Nothing. There’s replacement part supply or even creation in nature.
Of course, this makes perfect sense given evolution and other similar natural processes. It makes no sense if there were an actual biological designer behind it all.
