 Philosophers of biology typically understand biological individuals to be distinct from other kinds of entities in the biosciences, such as properties, processes, and events (though see Dupré 2012, Nicholson 2018, Nicholson &amp; Dupré 2018). Biological individuals have three-dimensional spatial boundaries, endure for some period of time, are composed of physical matter, bear properties, and participate in processes and events. Biological processes (such as photosynthesis) and biological events (such as speciation) lack such a suite of features. Although philosophers have explored the question of what makes anything an individual of any kind (e.g., Strawson 1959; van Inwagen 1990; Chauvier 2016; French 2014, 2016; Lowe 2016; Wiggins 2016), such questions are bracketed off here in order to concentrate on biological individuals (cf. Love &amp; Brigandt 2017).
