I was shocked watching a video clip of a paramecium. I can’t believe that a unicellular organism could interact with its environment that sensitively. I wonder how it doesn’t require a brain to do all that. Can you say where the paramecium’s information processing unit is? How does it store information? The information is pretty large as it knows how to swim making all those complicated flagellar movements, knows how to distinguish between food & obstacles, knows how to procure what food, also knows who its mates are & how to interact with them, etc. Some researches have shown that some Bacteria communicate among themselves. The genetic material with some static arrangement of some molecules simply can’t be behind all these, as for active interaction a dynamical system is required. Ofcourse, the information required to build the cell is very much contained in that chemical sequence. Then how is information processed & where is it stored?
