This editorial outlines the formation of a new special interest group (SIG) in evolution and psychiatry. The formative beginnings of the evolutionary psychiatry field and founding of the group in Ireland are presented, identifying central figures of the field and their contributions. Furthermore, key milestones and accomplishments are discussed with current and future directions. Additionally, foundational texts and seminal papers are included to guide the reader in their journey to discover more about evolution and psychiatry. We hope this will be of relevance to those interested in how SIGs form and also to clinicians with an interest in evolutionary psychiatry.
