Uniformitarianism and Fine Tuning

An argument:We often read in these forums that one cannot claim that physical phenomena such as radioactive decay operated in the past as they do in the present. This is said to apply to even the recent past, during which there have been living organisms.We also read that the physical constants of this universe are so finely tuned that any appreciable change would make life impossible.Yet, we do find that living beings do exist. Therefore, if fine tuning is true, there cannot have been significant changes in the physics of the universe in the recent past. Otherwise, life would have become impossible and would not occur now.A question:
How many creationist claims does all this invalidate?
