Baddecker's logic isn't bad but there are a few key things he doesn't quite understand.

1. The meaning of random mutation
2. The importance of C&E research


1.  Random mutation doesn't mean quite what you think it means.  It doesn't mean that the occurrence of mutation is random.  Mutations are inevitable and we know their causes.  Radiation, viruses, replication mistakes, and environmental toxins can all damage DNA.   

Replication mistakes C&E
We know that DNA polymerase makes mistakes at a rate of 1 in 10,000,000 nucleotide bases and the average rate in eukaryotes in 50 bases per second so that cause alone adds up to about 15 "typos" per month.  The "random" is about where in the 150 million base pairs, will the mutation occur.  Its not loation specific.  If you are typing a novel, no one can predict where in the novel your typo will occur. 

Environmental toxins/Radiation C&E
We know that free radicals or radiation can knock electrons off of DNA molecules, damaging or changing them.   Radiation and chemical toxins move through space randomly so no one could predict which part of your DNA will be hit or when this collision will occur but it is inevitable that radiation will hit your nucleotide molecules at the right angle to knock electrons off.

Virus C&E
Viruses literally hack into a cells DNA and change it. Again, no one knows when you will contract a virus, or what part of your DNA will be affected by that virus as viruses evolve quickly as well. 

2. We know that all of these things will happen, and we know the C&E but scientific research is not just about C&E, a lot of it is simply about finding correlation between two variables.  C&E is definitely more informative than correlation but a lot of times, correlation is alll we are able to pin down.
