 More general philosophical issues associated with evolutionary theory—those surrounding natural teleology, ethics, the relation of evolutionary naturalism to the claims of religious traditions, the implications for the relation of human beings to the rest of the organic world—continue as issues of scholarly inquiry. If contemporary neo-selectionist evolutionary theory displays continuity with select features of the theories of Darwin, alternative interpretations, such as the current movement known as evolutionary developmental theory or “evo-devo”, mark a return to presumably discarded traditions of the nineteenth and twentieth century that considered it essential to link evolution with embryonic development and with the effects of external conditions on inheritance (Gilbert 2015; Newman 2015; Laubichler &amp; Maienschein 2013, [eds] 2007; Gissis &amp; Jablonka [eds] 2011; Pigliucci &amp; Müller [eds] 2010; Amundson 2005; Gilbert, Opitz, &amp; Raff 1996). Such developments suggest that there are still substantial theoretical issues at stake that may alter the future understanding of evolutionary theory in important ways (Sloan, McKenny, &amp; Eggleson [eds] 2015).
