Dear colleagues, We are organizing a symposium "Adaptive Epigenetics" at the 3rd Joint Congress on Evolutionary Biology, which is taking place July 26-30 in Montreal, Canada. The goal of this symposium is to feature talks focused on the various ways that epigenetic mechanisms could contribute to evolutionary processes, especially to adaptation. We hope to assemble scientists from different fields working on theoretical and empirical questions involving adaptive epigenetics. The abstract is provided at the end of the message. Registration is now open, and abstracts can be submitted to be considered for this symposium. Please see the 2024 Conference info ( https://www.evolutionmeetings.org) for meeting info. Talks are accepted on a first-come-first-serve basis, and those that are not selected for a symposium will nevertheless be placed in one of the general sessions. Please don't hesitate to contact us if you have any questions about the symposium. Hollie Marshall James Ord Clare Vennay Clarissa de Carvalho Symposium abstract: The field of evolution is on the edge of a paradigm shift with the incorporation of epigenetic mechanisms changing how we view evolutionary processes. Epigenetics refers to potentially heritable chemical modifications that occur on the DNA of an organism. These chemical modifications can affect how genes function and can be induced by the environment. This paradigm is highlighted by the Unified Evolution Theory (2021), a modification of the Extended Evolutionary Synthesis which includes heritable environmentally induced epigenetics. This newly modified theory and specifically the extent to which epigenetics can play a role in species adaptation remains highly debated in some sub-fields but not others. A symposium directly addressing this topic will allow researchers from all areas to learn about the latest advances and evidence (or lack thereof) within evolutionary epigenetics, facilitating debate and knowledge sharing.
