  1. Question

    Could Nature produce any minimal lifeform and/or a single cell without Phosphorus?

    It is impossible to say what Nature could or could not do -- having only one basic form of life here on Earth, we really don't know what other possibilities might exist elsewhere. All I can say in reply is that all life on Earth uses phosphorus as part of its basic chemistry.
