DAVID: the kidney, along with the liver, is the master controller of many chemical levels in the body:-https://www.sciencedaily.com/releases/2016/04/160407221703.htm-David's comment: All of the chemicals controlled by the kidney, both salts and protein compounds are held in tight ranges of concentrations. Water volume in the body is also tightly controlled. In the Cambrian the kidney appears with no precursor. How? Not committees of thinking cells. I prefer saltation.-“Committees of thinking cells” are an explanation of saltation, not an alternative.
