Xiao He Grave site
1. Prehistoric Central Asia
Many things remain clouded in mystery regarding the ancient history of Central Asia. However, it is thought that agriculture started in the Tarīm Basin around 4000 BC.
Studies undertaken on the Tocharian language (an extinct Indo-European language) suggest that Indo-European peoples first arrived from West Asia moving into the Tarīm Basin around 2000 to 1000 BC (06).
Mummies found in Loulan (in the Xiao He Grave site (小河墓) (06), which are estimated to be 3,800 years old, show distinctly Caucasian features, and we therefore know that at one time Central Asia was home to Indo-European people.
