To me stuff like this is what proves evolution. There is no one in their right mind who could sit there and convince me that such an obtuse solution to move from point A to point B is "by design", vs. random evolution.
As a scientist who happens to also believe in a creator, I don't understand why evolution and intelligent design have to be mutually exclusive. Why can't a creator have designed evolution?
The fact that life on this planet has undergone -- and continues to undergo -- evolution is undeniable. That doesn't prove that God doesn't exist. A system that is not only capable of propagating itself indefinitely but also continually updates itself over centuries and millennia.. now that's a pretty impressive hack if you ask me.
A common refrain from those who want to disprove intelligent design is "this creature's adapted behavior isn't the most efficient way to accomplish this task, so therefore it was not designed by an all-knowing, all-powerful creator". Just because this spider's means of locomotion is an "obtuse solution" also doesn't mean it's not "by design".
Who says God doesn't have a bit of Rube Goldberg in him? You're presuming that he's trying to create the perfect organism and he just can't quite get it right. Maybe he realizes that if he created the perfect spider it'll freak the hell out of his humans who will then wipe it off the planet.
