ABSTRACT
Protobiology as a physics of becoming that can give birth to biology differs from the physics of being that emphasizes the preservation of invariance and symmetry and rejects emergent properties. Intrinsic partial fixedness of boundary conditions and the communication of conservedness proceeding at a finite velocity are compatible with each other. The third law of mechanics states no net contribution from forces of action and reaction. This no-net contribution admits two possibilities, either force equilibrium completed or force equilibration in the making. A particular example of mechanical motion in biology is seen in flagellar movement of eukaryote. Protobiology can be seen as an instance of internal measurement that accompanies the law of motion of one-to-many mapping type. Internal measurement in protobiology is not restricted to force equilibration as an agent materializing the null-conservedness of forces which the third law of mechanics implies. Protobiology is an attempt to identify a physics of becoming that can yield and give birth to biology.
