Sketching Biological Phenomena and Mechanisms [PDF]

open access: yesTopics in Cognitive Science, 2017
AbstractIn many fields of biology, both the phenomena to be explained and the mechanisms proposed to explain them are commonly presented in diagrams. Our interest is in how scientists construct such diagrams. Researchers begin with evidence, typically developed experimentally and presented in data graphs. To arrive at a robust diagram of the phenomenon
