Thanks Russ, I just have one question:

Can you show me evidence of one population or organisms where hereditary traits don't change from generation to generation?

I've looked around and it seems to me that all the populations of organisms living in the world today show changes in hereditary traits from generation to generation. The fossil record also supports this, as there are no two identical fossils. Genetics supports this as there are no two individuals with identical DNA.

So I've made this little theory that this is an ongoing process in all life forms.

I can invalidate this little theory by demonstrating one population of organisms that does not change hereditary traits from generation to generation, where all organisms are identical, but so far I have not found one: so can you help?

Just a basic scientific approach here: observation, theory, test.

Enjoy.
