Intro to Natural Limitation to evolutionary processes seen in population genetics

Maybe this old thread at EvC will serve as an introduction to my other favorite theme besides the obviousness of this Flood-wracked planet, which is the fact that the processes of "evolution" or the selection of traits that get passed on, involves other traits being passed up and sometimes dying out completely. Although the process may be so slow as to be undetectable over hundreds of generations, it can be very fast, and in all cases the general tendency is the LOSS of genetic potentials, the opposite of what would have to be the case were evolution true.
