Abstract Chamaerops humilis L. is the only Arecaceae species endemic to western Mediterranean. Here, de novo genome sequencing allowed discovering reasons behind its exclusive persistence within natural distribution area, although troubled environmental changes occurred. The genome, estimated at 3.44 Gbp, and annotation enabled identification of 60,555 genes 2.87 Gbp repetitive regions. Evolutionary analyses revealed a whole-genome duplication event 48.02 mya, shared with other palm species, later divergence from Phoenix dactylifera (17 mya). characterization gene types, KS values, uncovered multiple recent waves, presence C. humilis-specific duplicated involved in responses stress. Furthermore, expansions transposable elements were detected appear be associated major paleoclimatic events These genomic features likely contributed resilience long-term survival
