Marion J. Lamb
Marion Lamb is cited in this literature as co-author, with Eva Jablonka, of work on epigenetic inheritance. Later authors point to Jablonka and Lamb for inheritance mechanisms beyond the gene in single cells12, for epigenetic states that distinguish cell types3, and for a revived view of Lamarckian inheritance4.

Epigenetic inheritance in cells
Fernando and colleagues proposed a gene circuit that could learn an association between two signals in a single-celled organism. They cite Jablonka and Lamb (2005) for the claim that epigenetic inheritance certainly occurs in bacteria, single-celled fungi and protists1. They also send readers there for other mechanisms of epigenetic inheritance2. Their own argument was that a learned association could be inherited if the cell divided soon enough after learning.
Cell states and Lamarck
Watson and colleagues, writing on evolutionary transitions, cite Jablonka and Lamb (2006) for the point that liver cells differ from skin cells because of their epigenetic states3. Neuhof, Levin and Rechavi set Weismann's barrier against Lamarck's theory, which assumed continuity between generations. They note that this theory was until recently considered entirely incorrect, and they cite Jablonka and Lamb (2015) for that account4. The passages report the citation but do not detail the argument itself.
Use in bioelectric work
Levin (2023) argues that the number of heads a planarian cell collective produces is not directly encoded in the genome. He calls the underlying bioelectric process epigenetic in the broad, original sense of the word. For that usage he cites Jablonka and Lamb (1995) alongside other work by Jablonka5. In this setting the term is used to place bioelectric patterning among non-genomic forms of biological information.
There is no doubt that epigenetic inheritance occurs in bacteria, single-celled fungi and protests (Jablonka & Lamb 2005).
