Why aren't you also looking for more "embedded-ness" in/with the environment?
Really. Why? You can't just say "well, it does happen". HOW IS IT that real, concrete aspects of the environment are INTEGRAL AT THE INCEPTION OF EACH AND EVERY SIGNIFICANT NEW BEHAVIOR?? How do you expressly find these environmental aspects?? -- to an empiricist these will not be just qualitative "types of" things (or "extrapolations" of known phenomenon or by-analogy) _OR_ anything assumed, but actually really identified, in the physical environment.
[ This is simply basic empiricism, or an attempt at it (and not breaking with it or accepting a break with it). ]
