Was your body designed to change tires? Do you think the ability to change tires is not a survival trait? Was your body designed to lift and hurl small objects? Do you do it as well as an automatic pitching machine?
"Was your body designed to change tires?"
It is capable of it.
"Do you think the ability to change tires is not a survival trait?"
It is helpful sometimes. Other times it could get you killed.
"Was your body designed to lift and hurl small objects? Do you do it as well as an automatic pitching machine?"
My body does not pitch as well as a pitching machine can. My body is capable of pitching but is not a pitching machine. No machine has yet duplicated the functionality of the human body over all. You would have to make many machines to duplicate this functionality and even then it might not happen. The need for many machines to duplicate the functionality of the body demonstrates that the body is more efficient than the machines.
However, this point is not critical anyway.
Besides, according to your logic, it should not matter because a pitching machine is just performing a natural process, just like the body. Therefore you should not try to draw any conclusions about whether biological systems are more efficient.
