Recapitulation in Nested Evolutionary Dynamics
“3–4 million years ago: collective rock throwing…
500,000 years ago: control of fire
50,000 years ago: bow and arrow; fine tools
5,000 years ago: wheel and axle; sail
500 years ago: printing press with movable type; rifle
50 years ago: the transistor; digital computers”
Then I burst out laughing with a maturationist epiphany: this is exactly the same sequence of development I went though as a young boy! It started with collective rock throwing (I still have a scar inside my lip)..... then FIRE IS COOL!.... then slingshots…. and the wheels of my bike…. then writing and my pellet gun.... and by 7th grade, programming the Apple ][. Spooky.
It reminded me of the catchy aphorism: “ontogeny recapitulates phylogeny” (the overgeneralization that fetal embryonic development replays ancestral evolutionary stages) and recapitulation theories in general.
I’m thinking of Dawkin’s description of memes (elements of ideas and culture) as fundamental mindless replicators, like genes, for which animals are merely vectors for replication (like a host to the virus). In Meme Machine, Susan Blackmore explores the meme-gene parallels and derives an interesting framework for explaining the unusual size of the human brain and the origins of consciousness, language, altruism, religion, and orkut.
Discussions of the cultural and technological extensions of our biological evolution evoke notions of recapitulation – to reestablish the foundation for compounding progress across generations. But perhaps it is something more fundamental, a “basic conserved and resonant developmental homology” as John Smart would describe it. A theme of evolutionary dynamics operating across different substrates and time scales leads to inevitable parallels in developmental sequences.
For example, Gardner’s Selfish Biocosm hypothesis extends evolution across successive universes. His premise is that the anthropic qualities (life and intelligence-friendly) of our universe derive from “an enormously lengthy cosmic replication cycle in which… our cosmos duplicates itself and propagates one or more "baby universes." The hypothesis suggests that the cosmos is "selfish" in the same metaphorical sense that evolutionary theorist and ultra-Darwinist Richard Dawkins proposed that genes are "selfish." …The cosmos is "selfishly" focused upon the overarching objective of achieving its own replication.”
Gardner concludes with another nested spiral of recapitulation:
“An implication of the Selfish Biocosm hypothesis is that the emergence of life and ever more accomplished forms of intelligence is inextricably linked to the physical birth, evolution, and reproduction of the cosmos.”
