“…In particular, he refers to three subjects that shaped the main discussions that took place in Europe around biology: form (understood from cell theory and the development of individuals), function (from the idea of the "animal machine"), and transformation (with particular emphasis on the role of Darwin's ideas). More recently, in historiographical terms, the history of biology has focused on reconstructing localised episodes, both geographically (Alberti, 2001(Alberti, , 2005Kraft, Alberti, 2003) and theoretically (Morgan, 1980;Kraft, 2004;Erlingsson, 2009Erlingsson, , 2013Button, 2018). This paper intends to follow a historiographical line that, beyond seeking to understand biology in a broad sense, will attempt to reconstruct a scientific practice that emerged as part of the interaction between scientific and political interests in a specific geographical context, namely Great Britain in the second half of the nineteenth century.…”
