Existence Through Touch: Evolution's Unseen Threads

The basic functioning of neurons, shared between humans and jellyfish, highlights the simplicity in the structures of intelligence across species. While touch serves as the primary sensory input for jellyfish, the fundamental types of neurons—excitatory and inhibitory—are also present, indicating a shared evolutionary heritage. This shared neuronal framework reveals that the distinction in intelligence derives from the complexity of neural wiring rather than the basic building blocks themselves. The necessity for inhibitory and excitatory signals in reflex actions, as observed in primitive organisms like the Cnemoni, underscores the fundamental 'if this, not that' rule that governs organismal behavior, reflecting an evolutionary constraint that shapes survival mechanisms.
