It relates to the cascading rate doublings leading up to chaotic regimes. Well not just that. Sufficient complexity in the behavior hits a different threshold of emergent information exchange (intelligence).

hmm... but do we have any principle to tell what is "Sufficient" before-hand?

Probably newer and better thinking now, but a book I read about "The Edge of Chaos" suggested that self-organizing systems seem to find a sweet spot that is just chaotic enough. I don't think it is a measure, but a qualitative mode that is between periodic modes and full chaos.

still need to dig into Ilya Prigogine's work on dissipative structures: self-organization in systems in far-from-equilibrium conditions and irreversibility (finally time becomes important in physics again!) https://en.wikipedia.org/wiki/Ilya_Prigogine#Research …pic.twitter.com/b32zM2v0LI

Oh, that's an awesome reference! This is some of the sort of stuff I started working on in grad school until life took me elsewhere :D

I didn't start down this path until the NYT best seller, Chaos by Gleick and since have been on the lookout for these ideas where they appear. One inspiring direction was the book "Into the Cool" which was about living systems evolving to slow down the energy cascades with life.

Mostly living chemical cycles, but this are physical too as in the water cycles. Compare sunlight directly on mineral rock/sand vs. a forest that holds moisture and chemical energy throughout a complex matrix. Instead of the raw 5000K radiation flux from Sol, energy steps down.

Doing stuff with energy is about "free energy", which can be just dissipated in thermal radiation, or it can cascade as smooth and turbulent flows. Life operates in this free energy space by harboring little bits of energy and releasing it in controlled dance of reaction cycles.

"Into the Cool" seems to have key insights about universe's properties "thermodynamic imperative" "nature doesn't like gradients" leading to self-organizing phenomena like storms and life."Genetics is not enough" So true! Darwin's theory of evolution is descriptive,not predictive

I think lamarck has much more going for it now that rna can jump species and we are in a punctuated equilibrium. the idea of “into the cool” has explicitly guided my strategies!

horizontal or lateral gene transfer! "the movement of genetic material between unicellular and/or multicellular organisms other than by the ("vertical") transmission of DNA from parent to offspring (reproduction). HGT is an important factor in the evolution of many organisms"

"Most thinking in genetics has focused upon vertical transfer, but the importance of horizontal gene transfer among single-cell organisms is beginning to be acknowledged" https://en.wikipedia.org/wiki/Horizontal_gene_transfer …
