Original multidisciplinary research hereby clarifies the complex geodomestication pathways that generated the vast range of banana cultivars (cvs). Genetic analyses identify the wild ancestors of modern-day cvs and elucidate several key stages of domestication for different cv groups. Archaeology and linguistics shed light on the historical roles of people in the movement and cultivation of bananas from New Guinea to West Africa during the Holocene. The historical reconstruction of domestication processes is essential for breeding programs seeking to diversify and improve banana cvs for the future.plant genetics | historical linguistics | archaeobotany | diploid banana cultivars | triploid banana cultivars N ew multidisciplinary findings from archaeology, genetics, and linguistics clarify the complex geodomestication pathways-the geographical configurations of hybridization and dispersalthat generated the range of modern banana cultivars (cvs). Although recent molecular research, combined with the outcomes of previous genetic studies, elucidates major stages of banana domestication, such as the generation of edible diploids and triploids, it sheds only partial light on the historical and sociospatial contexts of domestication. The geographic distributions of genotypes involved in banana domestication require human translocations of plants, most likely under vegetative forms of cultivation, across vast regions. Linguistic analyses of (traditional) local terms for bananas reveal several striking regional-scale correspondences between genetic and linguistic patterns. These multidisciplinary findings enable the relative dating of the principal events in banana geodomestication and situate banana cultivation within broader sociospatial contexts. Archaeological findings provide a timeline to anchor and calibrate the relative chronology.

Multidisciplinary investigations at Kuk Swamp in the Highlands of Papua New Guinea show that agriculture arose independently in New Guinea by at least 6950 to 6440 calibrated years before the present (cal yr B.P.). Plant exploitation and some cultivation occurred on the wetland margin at 10,220 to 9910 cal yr B.P. (phase 1), mounding cultivation began by 6950 to 6440 cal yr B.P. (phase 2), and ditched cultivation began by 4350 to 3980 cal yr B.P. (phase 3). Clearance of lower montane rainforests began in the early Holocene, with modification to grassland at 6950 to 6440 cal yr B.P. Taro (Colocasia esculenta) was utilized in the early Holocene, and bananas (Musa spp.) were intensively cultivated by at least 6950 to 6440 cal yr B.P.
