The 2025 Genomic History Inference Strategies Tournament (GHIST) is live at https://ghist.bio! To celebrate the publication of the GHIST 2024 paper in Molecular Biology and Evolution (https://doi.org/10.1093/molbev/msaf257), we are extending the submission deadline to December 1st, 2025. There are many ways to infer population history, natural selection, or other evolutionary properties from genomic data, and it is often unclear which methods work best for which tasks. GHIST is an annual forum for the community to test inference approaches in an unbiased fashion. Each year, the GHIST organizers release simulated population genomic data sets and host a competition to infer various aspects of the processes that generated those data. From the submissions, the community will learn what approaches perform well or poorly in particular circumstances. And it is a great training opportunity! Top competitors will be invited as coauthors on the publication describing the year's competition and earn cash prizes. This year, GHIST consists of 5 demographic history inference challenges and 4 selective sweep detection challenges. You can use whatever approach you prefer to tackle each challenge.
