Well...if evolution doesn't have to take thousands or millions of years I suppose then that everything could have been created after their own kind about 6-10 thousand years ago and evolved into what we have today and the only COMMON descent would be God.
No, this is incorrect. What Nathan meant is that evolution is a matter of generations, not necessarily an amount of time. Insects have a very fast turn-over rate, and reproduce quickly enough that you can see changes rather quickly. Higher animals like us, other mammals, etc. live longer so it takes much longer to see changes because it takes longer to see a new generation. So it would necessarily take much longer to see changes in animals.
So when we look at evidence for evolution and speciation, the experiments are done with insects and plants because they can reproduce faster. If you do experiments with higher animals and speciation, it may take much longer than your lifetime to see results.
