TLDR
Further cytological study of Colocasia taro in the Pacific utilizing karyotypic data has produced a hypothesis for two separate lineages of the plant within contemporary populations, providing support for domestication in the western Pacific independent of diffusion of Asian cultigen forms.Abstract:
Further cytological study of Colocasia taro in the Pacific utilizing karyotypic data has produced a hypothesis for two separate lineages of the plant within contemporary populations. This provides support for domestication in the western Pacific independent of diffusion of Asian cultigen forms, but it is indicated that confirmation awaits more comprehensive karyotyping of Indian and Southeast Asian material.read more

Direct evidence for human use of plants 28,000 years ago: starch residues on stone artefacts from the northern Solomon Islands
TL;DR: Wickler and Spriggs as mentioned in this paper reported the earliest direct evidence for the prehistoric use of root vegetables, in the form of starch grains and crystalline raphides identifiable to genus.

Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea
TL;DR: Preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp indicate that both taro and yam species were processed on the wetland margin during the early and mid Holocene.

Biomolecular evidence for plant domestication in Sahul
TL;DR: Biomolecular markers reveal that for these crops at least, domestication has occurred in New Guinea and further east in Melanesia, and have obvious bearings on genetic resources programme strategies and future surveys.

Isozyme variation in taro (Colocasia esculenta (L.) Schott) from Asia and Oceania
Vincent Lebot,K.M. Aradhya +1 more
TL;DR: Results showed greater isozyme variation in Asia than in Oceania, with Indonesia being the area of greatest diversity and the majority of the Indonesian cultivars were different from the Philippine and Oceanian taro cultivars.
