:Barker, Miles. "Putting Thought in Accordance with Things: The Demise of Anaimal-based Analogies for Plant Functions." Science & Education 11: 293–304

:"This paper describes how today's learners sometimes construct analogies in which animal functions are the 'analog' and plant functions are the 'target', and that these analogies may '''impinge''' on their learning about plants." (293)

* William Harvey, blood circulation, published in 1628
