Abstract Hybridization is a prominent and influential phenomenon with significant implications for adaptive evolution, species distribution biodiversity. However, the intricacies of how hybridization influences genomic structure facilitates evolution still elude our full understanding. Analyzing whole genome data from seven populations within Eriocheir genus across diverse geographic regions, we have validated complex history between Chinese Japanese mitten crabs. This gave rise to two distinct ecological species: Hepu Russian crabs unique architectures adaptations. Genes related reproduction, development, temperature adaptation exhibit divergent selection signals, potentially contributing their phenotypic diversity niches. Meanwhile, genes associated namely Birc6 , Bap31 Poxn displayed robust evidence selective sweeps in crab. Notably, favored alleles these originated parental lineages during process. Furthermore, crab homoploid hybrid that an ancient event, resolving its longstanding taxonomic controversy. Our study sheds light on evolutionary highlights crucial role driving adaptation, range expansion, diversification Eriochier genus.
