After decades of debate about the existence of non-genetic inheritance, the focus is now slowly shifting towards dissecting its underlying mechanisms. Here, we propose a new mechanism that, by integrating non-genetic and genetic inheritance, may help build the long-sought inclusive vision of evolution. After briefly reviewing the wealth of evidence documenting the existence and ubiquity of non-genetic inheritance in a table, we review the categories of mechanisms of parent-offspring resemblance that underlie inheritance. We then review several lines of argument for the existence of interactions between non-genetic and genetic components of inheritance, leading to a discussion of the contrasting timescales of action of non-genetic and genetic inheritance.... |
