Would natural selection (and evolution), if given enough time, develop organisms that were perfect? ... or develop the "perfect" organism?
I don't think it is possible to have a perfect organism; just ones that are able to tolerate certain environments better then others. Like deer for instance; there are a large variety of deer (i.e. mule, whitetail, black, etc...) each that has been designed/adapter to survive with-in the environments that they are most populated in. If you take the deer (or anything) from their environment and put it in another, more then likely the majority would die with only the strong surviving (the begining of natural selection).
This would allow one generation to create the next but in order to grow any real numbers they will have to adapt to that environment. Over time they will not have the same characteristics that made them identifiable as being part of the group they were originally part of (they may change size, fur color, etc...). Also I believe that they would loose the information/ability to live in the original environment that they left.
What it boils down to is that; what makes one organism the strongest in one environment would/could make it the weakest in another and vise-versa. This is not to say that they aren't already some organisms that can live in both extremes (frozen tundra and desert) but also anywhere in between. It however would need to be studied to see if they are able to do that because of evolution or if they aways have been able to do so. Yet to the best of my knowledge, although there are some that can live without one or two of the life essentials i.e. oxygen, sunlight, etc... I am unaware of any organism is capable of living without all of them; which would qualify as the perfect organism.
