Unfortunately my friend has backed up his claims about degenerating genetics by claiming the 2nd law of thermodynamics claims this is what happens.
This is why I've recently stopped debating with creationists. They like to talk about things they know nothing about. Here is a problem that you can give to your friend there. If he can solve the problem, then we can go on.
A thermodynamic engine operates cyclically and reversibly between two temperature reservoirs, absorbing heat from the high temperature bath at 450K and discharging heat to the low temperature bath at 300K. How much work does the engine perform in one cycle of operation? Also, how much heat is discarded to the low-temperature bath if 1500J of heat is absorbed from the high temperature bath during each cycle?
Tell him that I can do this problem in less than 10 minutes because it is a very simple one. Then, tell him that in order to talk about the 2nd law of thermodynamics without looking like a fool you need to be able to do problems 20 times harder than this one.
He's not dead. He's electroencephalographically challenged.

Actually I did something just like that Lam. I gave him Boltzman's and Gibb's equations and asked him to use them to show how evolution is impossible, then I asked him to define "disorder" and show how the definition applies to either of the equations. (Statistical mechanics seemed so much more fun than Thermodynamics )
