Applied Octopus consciousnessConvergent evolution

By Peter Godfrey-Smith

Summary

Octopuses: 500M neurons, 2/3 in arms, individual personalities, tool use, camouflage, play. Last common ancestor with humans ~600M years ago. Nervous system is decentralised — arms think semi-autonomously. Argues consciousness evolved independently multiple times.

Why It Matters

Octopus represents the most alien consciousness known — a "second experiment" in intelligent life. If convergent, consciousness is a natural expected outcome of certain evolutionary pressures.
