I say that we have a near perfect design for our hands for the variety of tasks required to advance humans.
And the reply is that hole in the road is just the right shape for the puddle.
I do not get it. Please explain this one?
ETA: I googled this concept and found that Douglas Adams imagined this. I still don't get it. Must be my lack of imagination.
You're joking. Near perfect design?!
Okay first of all,there's the fact we require so much water. Second, we can barely regulate our own temperatures and we require clothing to survive ("dying of exposure", as in exposure to nature). Third, our skin is weak and can be so damaged just by the SUN (the source of all energy on this planet) that we have to hide from it or die!
Fourth, many of our joints are so badly suited to their intended purposes that they frequently need replaced after 50-some odd years of use. Fifth, not to mention the discs between our vertebrae, which wear out as a matter of course and often impinge on the spinal cord, causing paralysis.
Sixth, we are so darn squishy any number of things other critters survive easily kill us (ie a cat can fall seven floors, we break our legs at one).
Seventh we use our nutritional intake so inefficiently that other beings survive easily off our wastes. Same with water. We excrete as much as we use.
Eighth autoimmune disorders. Meaning the immune system kills the body itself.
Ninth, our complex brains are ripe for dysfunction, which we call mental illness.
Tenth, we are jerks. We call it "human nature" when we do something *******-ish, especially in large groups. And it is. It is our nature,the way we are wired, that makes us riot and loot and go to war. Not exactly a great "design".
Eleventh, babies are helpless until they are at least 7, and require adult assistance until they are in their teens. What a waste of energy! Wouldn't a better "design" mature more rapidly?
Twelfth, we have an innate tendency to believe in nonsense like supernatural dieties.
I could go on. Books have been written about how badly "designed" humans are.
Eta I realize he specifically said "hands" but I wanted to address the entire idea.
Thirteenth: carpel tunnel syndrome. Using our hands repeatedly for their intended purpose makes it so you can't use your hands any more. Also arthritis. Also the fact that everything we designed, we designed for our hands...its like saying feet must be perfectly designed because shoes fit them.
