Objectives：
To understand early trans-continental dispersals of ancient human groups and their occupation of diverse environments.
Scientific Issues：
1) The dispersals and behavioral traits of archaic humans across Eurasia in the late Middle and Upper Pleistocene;
2) Modern human dispersals and their interactions with archaic humans;
3) Prehistoric hunter-gatherers’ adaptation to extreme environments, such as arid, alpine, and tropical environments.
Pictures:
Archaeological excavation at Baishiya Karst Cave revealed occupation history of Denisovans, archaic humans in Eurasia, and their adaptation to the alpine environments of the Tibetan Plateau.
