Abstract
Molecular markers for tracing animal sample origins and compositions are critical for applications such as parasite detection, contamination screening, and sample authentication. Among these, microRNAs have emerged as promising candidates due to their deep conservation, near‐hierarchical evolution, and stability. I here review the suitability of microRNAs as taxonomic and also phylogenetic markers and show how careful annotation efforts and the establishment of the curated microRNA gene database MirGeneDB and tools like MirMachine have revitalized microRNA research. These advancements enable accurate phylogenetic and taxonomic studies, highlighting microRNAs' potential in resolving long‐standing questions in animal relationships and extending to applications in ancient DNA and environmental RNA analysis. Future research must focus on expanding microRNA complements across all Metazoa and further improving annotation methodologies.
期刊介绍：
Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification.
Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
