 Charles Darwin’s version of transformism has been the subject of massive historical and philosophical scholarship almost unparalleled in any other area of the history of science. This includes the continued flow of monographic studies and collections of articles on aspects of Darwin’s theory (Richards and Ruse 2016; Ruse 2013a, 2009a,b, 2008; Ruse &amp; Richards 2008; Hodge &amp; Radick 2003 [2009]; Hösle &amp; Illies [eds] 2005; Gayon 1998; Bowler 1996; Depew &amp; Weber 1995; Kohn 1985a). The continuous production of popular and professional biographical studies on Darwin provide ever new insights (Ruse et al.  2013a; Johnson 2012; Desmond &amp; Moore 1991, 2009; Browne 1995, 2002; Bowlby 1990; Bowler 1990). In addition, major editing projects on Darwin’s manuscripts and Correspondence, now completed through 1878, continue to reveal details and new insights into the issues surrounding Darwin’s own thought (Keynes [ed.] 2000; Burkhardt et al. [eds] 1985–; Darwin 1836–1844 [1987]). The Cambridge Darwin Online website (see Other Internet Resources) serves as an international clearinghouse for this worldwide Darwinian scholarship.
