The genetic history of the Southern Caucasus from the Bronze Age to the Early Middle Ages: 5,000 years of genetic continuity despite high mobility
New genetics study indicates that Pre-Austronesians emerged in China over 10,000 years ago, living by marine foraging. Around 7–10Kya, they mixed with ancient northern Chinese (Shandong), adopting agriculture and evolving into Proto-Austronesians.
High-quality genomic data generated from 131 ancient individuals from Great Scythia and neighboring regions of the Bronze Age and the Iron Age. Including relationships between Scythians and elite Scythians.

Bronze and Iron Age genomes reveal the integration of diverse ancestries in the Tarim Basin
DNA predicted faces of archaic humans differ more from those of Europeans than from Africans. In genetically modelled Neanderthal faces, 15 of 16 DNA-predicted facial features are in line with skull evidence.
The documentary evidence from rock art and its implication of a northern center of yak domestication support the argument for a background in the Early Bronze Age Afanasievo culture.

“Within rock art of the northern Altai mountains, there is ample pictorial evidence that transhumance dependent on domesticated yaks emerged by the late third millennium BCE in the Mongolian Altai.”
