Abstract EN
Asexual organisms, often perceived as evolutionary dead ends, can be long-lived and geographically widespread.
We propose that epigenetic mechanisms could play a crucial role in the evolutionary persistence of these lineages.
Genetically identical organisms could rely on phenotypic plasticity to face environmental variation.
Epigenetic modifications could be the molecular mechanism enabling such phenotypic plasticity; they can be influenced by the environment and act at shorter timescales than mutation.
Recent work on the asexual vertebrate Chrosomus eos-neogaeus (Pisces: Cyprinidae) provides broad insights into the contribution of epigenetics in genetically identical individuals.
We discuss the extension of these results to other asexual organisms, in particular those resulting from interspecific hybridizations.
We finally develop on the evolutionary relevance of epigenetic variation in the context of heritability.
