Yep, that's what Nick meant I assure you. He's slapping his forehead thrice for making that reversal.

Nick, Good to hear from you. Nice description of entropy in animal behavior!

I agree with pretty much everything you say. I'm concerned about this sentence, though.

When entropy is low … i.e., when there is a particularly steep gradient in some part of the universe, Nature contrives a means for reducing that entropy and that means, paradoxically is to INCREASE entropy in some localized portion of the universe in order to more efficiently decrease it over all.

By a particularly steep gradient, I assume you mean any sharp change of some property. The gradient is in some property--not any particular property, and especially not necessarily in entropy.

I'm guessing you meant to say that Nature contrives a means for increasing that entropy. (You did say it started out low. I agree with that. Smoothing out the gradient would increase the entropy.)

That would increase entropy locally and globally.
