    Three Epigenetic Information Channels and Their Different Roles in Evolution.Nicholas Shea, Ido Pen & Tobias Uller - 2011 - Journal of Evolutionary Biology 24:1178-87.
    There is increasing evidence for epigenetically mediated transgenerational inheritance across taxa. However, the evolutionary implications of such alternative mechanisms of inheritance remain unclear. Herein, we show that epigenetic mechanisms can serve two fundamentally different functions in transgenerational inheritance: (i) selection-based effects, which carry adaptive information in virtue of selection over many generations of reliable transmission; and (ii) detection-based effects, which are a transgenerational form of adaptive phenotypic plasticity. The two functions interact differently with a third form of epigenetic information transmission, (...)

    The Information Value of Non-Genetic Inheritance in Plants and Animals.Sinead English, Ido Pen, Nicholas Shea & Tobias Uller - 2015 - PLoS ONE 10 (1):e0116996.
    Parents influence the development of their offspring in many ways beyond the transmission of DNA. This includes transfer of epigenetic states, nutrients, antibodies and hormones, and behavioural interactions after birth. While the evolutionary consequences of such nongenetic inheritance are increasingly well understood, less is known about how inheritance mechanisms evolve. Here, we present a simple but versatile model to explore the adaptive evolution of non-genetic inheritance. Our model is based on a switch mechanism that produces alternative phenotypes in response to (...)
