I guess that's why I also believe that the government should mind its own business. All living creatures are remarkable, and I have spent hours just considering individual items such as the eye. I certainly can't think of any other animals that can run, crawl, swim, jump, and climb as well as a human, and humans are also remarkably resilient. Even the poorest of nutrition takes years to actually kill a human, and we can often survive incredible amounts of trauma. Sure, other animals can run faster, or swim faster, or last longer underwater.
Some animals can climb more quickly and jump higher, too.
It would be easy to start picking individual features and start wishing that our knees and elbows bent both ways, for example. Although I am no biology expert, I'm willing to bet that making such a change would cause other problems, such as weakening the effect of the muscles attached to those joints, or causing extra strain on the bones. I'll keep what I've got, thanks.
