Coasellular morphogenesis applies the Coase theorem from economics to biological development. Named after economist Ronald Coase, this theorem suggests that under certain conditions, parties can negotiate solutions to externality problems regardless of initial property rights.

In this biological context, individual cells act as economic agents that negotiate their morphological states through transaction costs. Each cell maintains energy for transactions and uses neighboring cells as distributed memory, creating emergent developmental patterns.

Key concepts include: Coase theorem, transaction cost economics, cellular automata, distributed cognition, bioelectric signaling, and the economics of morphogenesis.
