Evoldir title: Montreal.(Un)PredictableEvolution.Jul26-30 Subject: Symposium on the (Un)Predictability of Evolution Dear colleagues, We are happy to announce the symposium "Empirical and Conceptual Insights on the (Un)Predictability of Evolution" at this year's 3rd Joint Congress on Evolutionary Biology in Montreal on 26-30 July. Submission of talks for the symposium is open to anyone attending the conference. You can register here: https://www.evolutionmeetings.org/registration.html. The goal of this symposium is to bring together empirical, theoretical, conceptual and philosophical insights on the predictability of evolution. With a long tradition in evolutionary biology, the "predictability topic" has recently gained greatly renewed interest, with growing attention also in other (sub-)fields such as ecology, speciation, and genomics. This is in part due to the advent of powerful recent technologies (for example, investigations involving aDNA or in silico and synthetic experimental approaches), several long-term field studies and experiments, controlled evolve-resequence experiments, as well as drastic real-life experiences for many of us in form of the COVID-19 pandemic. It therefore also seems of particular importance to re-consider and clarify the conceptual framework of predictability in science in general, and in evolutionary research specifically. We hope this symposium will bring together broad and diverse empirical, theoretical and conceptual perspectives on the types, function and value of predictions in evolutionary research, the aspects that limit or facilitate predictability, as well as examples demonstrating the relevance of predictions in our research. If your work is relevant to any of these or related questions, please consider submitting an abstract to our symposium! For some more information, the symposium abstract is attached below. In case of questions, please don't hesitate to contact us. Lead Organizers: Marius Roesti (marius.roesti-AT-unibe.ch) and Brian Langerhans (langerhans-AT-ncsu.edu) Additional Organizers: Andrew Hendry and Jonathan Losos Symposium abstract: The ability to make accurate predictions is often taken as a hallmark of strong scientific understanding. How good are we in making predictions about evolution and how can we actually test these predictions? What do we want to predict and how do we generate predictions? What limits our predictability and are these limits inherent or surmountable? And what might we gain by accurately predicting evolution? Our symposium will foster crosstalk among researchers with different perspectives on and approaches to these questions. We are excited to welcome innovative empirical (e.g., large-scale/long-term experimental or novel comparative), theoretical (e.g., synthetic, mathematical), and philosophical contributions, as well as historical perspectives on the (un)predictability of evolution. We further encourage submissions addressing predictability of evolutionary change across all levels of biological organization (e.g., genomic, cellular, morphological, behavioral, ecological communities).
