Monist vs. Dualist Experiment?

[Neo-Scholastic]

First error: 3. Evolutionary processes cannot select for features that do not affect behavior. Evolutionary processes cannot select for features that do not affect survival - would be more appropriate. While behavior does affect survival, it is not the only factor that determines it.... In terms of energy consumption, the brain is a very costly organ....That is what awareness is - a system that monitors the mental activity itself. And this is the advantage it was selected for.

I will concede that survival is more appropriate. That substitution does not undermine the argument. How does improved energy efficiency give a physical system phenomenal qualities?

Second error: 4. If awareness supervenes on cognition, then awareness is causally inert and cannot influence behavior. Establishing awareness' supervenience over cognition is not sufficient to establish it as causally inert and non-influential on behavior....(later)... the phenomenal process is a specific form of physical process in action. In which case, it is both causally relevant and reducible

This premise addresses the problem of over-determination that plagues your philosophy of mind. If phenomenal properties are reducible to physical events then they are not causally relevant. You have just given a name to a large set of related events. If mental properties occur simultaneously with physical processes then qualia are just along for the ride doing nothing. They neither steer nor propel. If qualia actually do something it is over and above what the physical processes are doing just fine by themselves.

Third error:6. And thus, knowledge does not depend on any significant correspondence between awareness and cognition...Even if natural selection were unable to explain the correspondence between awareness and cognition, this conclusion would still be invalid.

By itself no. In the context of the argument it is valid. Evolutionary pressures do not explain how our capacity for rational knowledge came to be. As such there is no materialist explanation for why they should exist at all. The physical universe can do everything it already does without any subjective awareness of any kind.
