Life, its origin, and its distribution: a perspective from the Conway-Kochen Theorem and the Free Energy Principle

Chris Fields aand Michael Levin

We argue here that the Origin of Life (OOL) problem is not just a chemistry problem but is also, and primarily, a cognitive science problem. When interpreted through the lens of the Conway-Kochen theorem and the Free Energy Principle, contemporary physics characterizes all complex dynamical systems that persist through time as Bayesian agents. If all persistent systems are to some – perhaps only minimal – extent cognitive, are all persistent systems to some extent alive, orare living systems only a subset of cognitive systems? We argue that no bright line can be drawn, and we re-assess, from this perspective, the Fermi paradox and the Drake equation. We conclude that improving our abilities to recognize and communicate with diverse intelligences in diverse embodiments, whether based on familiar biochemistry or not, will either resolve or obviate the OOL problem.

WILD CLOCKS 

by David Farrier

Attentive to the loss of age-old ecological relationships as “wild clocks” fall out of synchronization with each other, David Farrier imagines an opportunity to renew the rhythms by which we live.

Pile o’Sápmi Supreme

In every living thing, there ticks a clock. “Lodged in all is a set metronome,” wrote W. H. Auden: when May comes round, birds “still in the egg, click to each other ‘Hatch!’” and “October’s nip” is the signal for trees to release their leaves.

Once, these rhythms comforted and consoled, orchestrating innumerable ecological relationships and offering glimpses of the greater wheels within which our small lives turn. But as climate breakdown takes hold, more and more species are struggling to keep time as they once did. Biological clocks that evolved an exact synchronization over millions of years are falling out of sync: the beat does not fall where it should; syncopation becomes dissonance. Failing wild clocks are resulting in misalignments in time between predators and prey, herbivores and plants, or flowers and pollinators. The results can be catastrophic, as breeding seasons fail and the long-held relationships that weave species together around shared needs fray. In Australia, mountain pygmy possums are leaving hibernation before the emergence of their preferred food, the bogong moth, risking starvation. Plants are losing touch with their pollinators: warm springs in Japan have led to earlier flowering of spring-ephemeral plants relative to their pollinating bees. One study warns that the timing of phytoplankton blooms could be shortened if the oceans continue to warm, introducing a calamitous mismatch at the very base of the marine food chain.

In a time of ecological crisis, it can be difficult to know exactly what time it really is.
