Epigenetically facilitated mutational assimilation: epigenetics as a hub within the inclusive evolutionary synthesis ArchiMer
Danchin, Etienne; Pocheville, Arnaud; Rey, Olivier; Pujol, Benoit; Blanchet, Simon.
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....

Offspring development and life-history variation in a water flea depends upon clone-specific integration of genetic, non-genetic and environmental cues ArchiMer
Harney, Ewan; Paterson, Steve; Plaistow, Stewart J..
Theory predicts that offspring developmental strategies involve the integration of genetic, non-genetic and environmental ‘cues’. But it is unclear how cue integration is achieved during development, and whether this pattern is general or genotype-specific. In order to test this, we manipulated the maternal and offspring environments of three genetically distinct clones of the water flea Daphnia magna taken from different populations. We then quantified the effect that the genotype, maternal environment and the offspring environment had on the development and life-histories of the three different clones. Mothers responded to the same maternal environments in different ways, resulting in clone-specific maternal effects on neonate size. Offspring responses...
