Aviv Bergman on The Evolution of Robustness and Integrating The Disciplines
COMPLEXITY
Is There a Reservoir of Wide Divergence in Populations?
Thereis always a reservoir of narrow divergence in populations. This is a kind of bet hedging against different environments. As an environment becomes more unstable, then the generalists that were punished in a stable regime and a turning pro. You get things like listrasauris, which was almost the only thing survived the permian mass extinction.
Ask any martial artist: It’s not just where a person strikes you but your stance that matters. The amplitude and angle of a blow is one thing but how you can absorb and/or deflect it makes the difference. The same is true in any evolutionary system. Most people seem to know “the butterfly effect” where tiny changes lead to large results, but the inverse also works: complex organisms buffer their development against adverse mutations so that tiny changes cannot redirect the growth of limbs and other organs. It takes a lot to shake the pattern of five fingers on a hand, or five toes on a paw. This is robustness: how much change can something soak up before it transforms? The question leads us into a secret garden of cryptic variation: mutations waiting for their moment, pieces sitting in place that might suddenly and radically metamorphose in changing circumstances. It’s why evolution stutters, halts and leaps, and maybe it can help us think about society and mind in ways that deepen comprehension of the tangled and surprising forces playing out at all scales, in society and in ecology. For quests as deep as these, we need to wear new lenses and train inquiries stereoscopically. How can and do the sciences and the humanities inform each other as we keep evolving — not just biologically, but culturally? Can we triangulate the truth by holding theories side by side and looking through them all together?
Welcome to COMPLEXITY, the official podcast of the Santa Fe Institute. I’m your host, Michael Garfield, and every other week we’ll bring you with us for far-ranging conversations with our worldwide network of rigorous researchers developing new frameworks to explain the deepest mysteries of the universe.
This week, we speak with Aviv Bergman (Google Scholar), External Professor of the Santa Fe Institute and Director of the new Albert Einstein Institute for Advanced Study in the Life Sciences.
