One example of unity and diversity in biological reasoning. Note that examples using a broader set of scales (e.g., ecosystem) could be utilized. a Within a biological scale (in this case, the scale of organism), reasoning about living systems lacks unification and is organized by taxonomic contexts, experiential instances, and case examples. b Within a biological scale (in this case, the scale of organism) reasoning about living systems is characterized by abstract models transcending organismal type or lineage (i.e. conceptual unity). c Among biological scales (in this case, molecule, cell, organism), reasoning about living systems lacks unification and is organized by macroscopic (organismal), microscopic (cellular), and molecular (biochemical) levels of biological organization. d Among biological scales (in this case, molecule, cell, organism), reasoning about living systems at is characterized by abstract models linking biological scales (i.e. conceptual unity)
