 Whatever one says about the intricacies of such examples, in addition to individuals delineated by evolutionary criteria there are also what Thomas Pradeu calls physiological individuals. These are biological individuals individuated by appeal to criteria such as having a metabolism and being governed by internal control mechanisms of various kinds. For Pradeu, each physiological individual is “a functionally integrated and cohesive metabolic whole, made of interdependent and interconnected parts” (Pradeu 2016b: 807; see also Godfrey-Smith 2009: 71).
