It also looks to me like the post isn't careful enough in distinguishing fitness-maximizing vs. adaptation-executing.

I invite you to distinguish between them.

When the environment changes more rapidly, or adaptations are adopted more slowly, adaptation-execution drifts further from fitness-maximization.

Also, organisms are always adaptation-executors rather than direct fitness-maximizers.

What are you guys talking about, exactly? Phil describes evolution as an optimisation process - which seems fair enough to me. Are you three "adaptation-execution" folk trying to deny that evolution acts as an optimisation process? If not, what does all this have to do with Phil's original post?

I'm not sure exactly what point Steven was making, I was merely responding to Phil's challenge to distinguish between fitness-maximization and adaption-execution.

What do you mean by adaptation-execution?
