 In response to the DST rejection of multiple channel accounts of inheritance, Griesemer et al. (2005) note the multiple ways in which channels can be independent from one another. Channels may be individuated as separate channels physically, chemically, or biologically, regardless of whether they are statistically independent information channels. Additionally, causal independence should not be required for individuating inheritance channels. While Jablonka and Lamb use a notion of biological information to characterize inheritance systems, they are not individuated based on statistical independence, but rather mechanistically (or, more accurately, mechanismically, that is by identifying classes of inheritance mechanisms) and by biological function.
