[2] In 2016, a rock shelter was identified in Yunnan, China, 40 km from the border with Myanmar, where artifacts belonging to the Hoabinhian technocomplex were recognized, dating from 41,500 BCE.
As a result of her work the First Congress of Prehistorians of the Far East in 1932 agreed to define the Hoabinhian as: a culture composed of implements that are in general flaked with somewhat varied types of primitive workmanship.
It is characterised by tools often worked only on one face, by hammerstones, by implements of sub-triangular section, by discs, short axes and almond shaped artifacts, with an appreciable number of bone tools (Matthews 1966).Despite the general terms of the definition, Colani's Hoabinhian is an elaborate typology as indicated by the 82 artifacts from Sao Dong that Colani classified into 28 types (Matthews 1966).
Problems with Colani's typology were exposed by Matthews (1964) who analysed metric and technological attributes of unifacially flaked cobble artifacts from Hoabinhian levels at Sai Yok Rockshelter, Kanchanaburi Province, west-central Thailand.
His aim was to determine if Hoabinhian artifact types described by Colani could be defined as clusters of constantly recurring attributes such as length, width, thickness, mass, length-width ratio and cortex amount and distribution.
Recent archaeological research indicates that variation in Hoabinhian artifacts across regions are largely influenced by local, region-specific proximity to resources and changes in environmental conditions.
[12] Beyond this core area, some archaeologists argue that there are isolated inventories of stone artifacts displaying Hoabinhian elements in Nepal, South China, Taiwan and Australia (Moser 2001).
Gorman (1971) claimed that Spirit Cave included remains of Prunus (almond), Terminalia, Areca (betel), Vicia (broadbean) or Phaseolus, Pisum (pea) or Raphia lagenaria (bottle gourd), Trapa (water caltrop), Piper (pepper), Madhuca (butternut), Canarium, Aleurites (candle nut), and Cucumis (a cucumber type) in layers dating to c. 9800-8500 BP.
While Solheim noted that the specimens may 'merely be wild species gathered from the surrounding countryside', he claimed that the inhabitants at Spirit Cave had 'an advanced knowledge of horticulture'.
This method in particular was found to be especially useful in determining reduction intensity and may prove instrumental in answering broader archaeological questions involving subsistence, geographic range, and domestication.
However, at Tham Lod, a high frequencies of pre-processing (CPM) but a residential mobility strategy (ODM) and a low intensity of occupation (PCM) was observed: We can see an internal conflict between models.
[18][19] Among present-day populations, the Andamanese Onge and Jarawa, and the Semang (also known as "Malaysian Negritos") and Maniq in the interior of the Malay Peninsula are genetically closest to the sampled ancient Hoabinhian individuals.
