 Alexander Badyaev suggests an evolutionary continuum of inheritance systems that reflect the extent or stage of assimilation from epigenetic (in the broad sense of Jablonka and Lamb) to genetic inheritance. Parental effects may be a transient stage along this continuum, whose assimilation depends on the dynamics of the environment, and other constraints (Badyaev 2009; Badyaev &amp; Uller 2009; Helanterä &amp; Uller 2010; see also: Yona et al. 2015).
