Developmental biologist whose concept of generative program vs descriptive program is cited as foundational.

Claims (1)

claim

In embryological development, chemistry and cell migrations are mechanisms that do the work but are simply not the principal thing going on — the fifteen properties and their unfolding are.
contradicts
Alexander's interpretive priority claim distinguishing mechanistic substrate from the morphogenetic principle at work
