“Of all kinds of biological novelty, Beslon identified coevolution and major transitions as the two most closely related to open-endedness.” cc

Innovations grow exponentially with complexity. Innovation can be practically unbounded, even in finite arenas, if the number of levels of complexity in the system is allowed to grow.

For a system to grow in complexity, it has to be able to evolve building blocks, which can be combined to create higher-level building blocks, which can be combined... unbounded composition https://twitter.com/gordonbrander/status/1219110402832756737?s=21 …https://twitter.com/gordonbrander/status/1219110402832756737 …

“Evolutionary dynamics is very different from attractor dynamics: It behaves somewhat like an attractor on the short term, but over a longer term, instabilities lead to the generation of innovation.”

Nearing the point of maximal optimization, there is increased risk of disruptions. Optimized = fragile. Disruptions force evolution to explore new directions. https://twitter.com/chumulu/status/1098270697183424512?s=21 …https://twitter.com/chumulu/status/1098270697183424512 …

“The ecosystem consolidates into a highly organized network, as each agent seeks to eke out $ from its position in the value chain. Keystone species appear at critical points. A shock demolishes one of the keystone species, causing cascade failure.”http://gordonbrander.com/pattern/punctuated-equilibrium/ …

What processes lead to sequestration of information in units that can serve as evolvable elements? A promising mechanism: “alternation between unstable dynamics and contracting, fixed-point dynamics. Alternation forces the system to produce information bottlenecks.”
