WebbA corollary of the independent origin of neurons from ancestral secretory cells is the convergent evolution of synapses and synaptic signaling. Indeed, the eukaryotic exocytosis machinery (formation and the release of secretory vesicles) can independently recruit various uptake systems (transporters) and receptor proteins.
