Biological systematics is about the classification of life given the diverse evolutionary history, morphology, and genetic features of living things. In this episode, Haber and Velasco discuss a range of philosophical issues raised by biological systematics, with a focus on species classification. They consider views of species as natural groupings (6:37), as lineages (17:26), and as natural kinds or homeostatic property clusters (33:38). Haber defends a view of species as individuals (44:28), and Velasco raises doubts about that view (55:33). Velasco presents a view of species as a rank (66:25). They conclude by discussing naming and reference in biological systematics (74:38).
