Abstract
The logic of molecular developmental biology fails to explain embryogenesis. A new approach, Janus-faced control, involving both top-down control by differentiation waves and bottom-up control via the mechanical consequences of cell differentiations, may be needed. This obviates problems inherent in reductionism with an explicit, testable mechanism.
