These slow rates are applied to rocks that have very little parent isotope left in them, its assumed the decay from parent to daughter occurred at the same rates as today.
Nope. It's not an assumption. At all.
It's a conclusion based on what we know about physics and more particlularly the different methods of radiocative decay. It seem as if mindspawen doesn't know the difference between the words 'assumption' and 'conclusion'. They're not the same.
