> Having a body which changes over time that interacts with a world that changes over time makes animal learning not statistical (call it, say, experimental). That animals fall into skinner-box irrational behaviour can be modelled as a kind of statistical learning, but it actually isnt.

RL is doing just this, simulating an environment. And we can have an agent "learn" in that environment.

I think tying learning to a body is too restrictive. The

You strongly rely on the assumption that "something else" generates the statistics we observe, but scientifically, there exists little evidence whether that "something else" exists (see eg the Bayesian brain).
