If you really wanted to take the time to understand how it works, then you would already have done so from at least some scientific and/or prominent univesity websites or used the reference books at the library. Once you do so, then you will realize just how silly your first question is.A question for the "Evolutionist" camp...
If mankind evolved from a "Less perfect" form...
and the theory of evolution suggests that as a basic premise...how is it that the less perfect form is still in existence?
When I place my car key in the ignition switch and use my opposable thumb in combination with "higher thinking skills" to drive an invention (not created by apes)to the zoo; should it possible to see a live example of the less perfect form at the zoo?
Just how is that "evolution" thing supposed to work?
Also, you imply that homo sapiens sapiens is "perfect." How do you figure that since we get far more diseases than other higher primates from which we, sapiens sapiens, branched at least tens and tens of thousands of years ago? What you deem as "perfect" seems quite the opposite and holds so many imperfections perhaps that you aren't aware of yet...
