Assuming an approach that attempts to draw metaphysical conclusions by analyzing how multifaceted practices of science work, I tie the results of my survey of protein classification practices to the debate over natural kinds. I address which classificatory practice is likely to pick out a natural kind. I defend the thesis that dynamics is a fundamental description of proteins as kinds. This view is widely held in biochemistry but is absent from philosophical literature on biochemical kinds.ETDIn Copyrightnatural kindsThesis
