Middle Stone Age humans in high-altitude Africa Recent archaeological research has produced evidence of the earliest human occupation of high-altitude habitats in the Andes and the Tibetan Plateau. Ossendorf et al. now present the oldest evidence of human settlement and adaptation to areas above 4000-meter elevation in Africa (see the Perspective by Aldenderfer). Their excavations at a rock shelter in the Bale Mountains of Ethiopia reveal obsidian artifacts and faunal remains, including… 
Clearing the (high) air
TLDR
Findings of a human presence at the Fincha Habera rock shelter that dates as far back as 31,000 to 47,000 years before the present are reported, marking the close of the last glacial period.
A spatiotemporally explicit paleoenvironmental framework for the Middle Stone Age of eastern Africa
Eastern Africa has played a prominent role in debates about human evolution and dispersal due to the presence of rich archaeological, palaeoanthropological and palaeoenvironmental records. However,
Biomolecular Evidence of Early Human Occupation of a High-Altitude Site in Western Central Asia During the Holocene
Reconstructions of early human occupation of high-altitude sites in Central Asia and possible migration routes during the Holocene are limited due to restricted archeological sample material.
Biocultural evidence of precise manual activities in an Early Holocene individual of the high-altitude Peruvian Andes.
TLDR
These findings provide the first biocultural evidence to confirm that the lifestyle of some of the earliest Andean inhabitants relied on habitual and forceful precision grasping tasks.
Hominin occupation of the Tibetan Plateau during the Last Interglacial Complex
Nonuniform Late Pleistocene glacier fluctuations in tropical Eastern Africa
TLDR
A chronological comparison for the Ethiopian Highlands in comparison with other East African Mountains reveals that glaciers in Eastern Africa responded in a nonuniform way to past climatic changes, indicating a regionally varying influence of precipitation, temperature, and orography on paleoglacier dynamics.

The preservation of archaeological remains and environmental information in a sediment accumulation can vary in caves and rockshelters, depending on external climatic conditions, and the

Paleoindian settlement of the high-altitude Peruvian Andes
TLDR
These results demonstrate that despite cold temperatures and low-oxygen conditions, hunter-gatherers colonized extreme high-altitude Andean environments in the Terminal Pleistocene, within about 2 ky of the initial entry of humans to South America.
Long-distance stone transport and pigment use in the earliest Middle Stone Age
TLDR
Three papers present the oldest East African evidence of the Middle Stone Age (MSA) and elucidate the system of technology and behavior associated with the origin of Homo sapiens and present evidence for the demise of Acheulean technology that preceded the MSA.
The earliest human occupation of the high-altitude Tibetan Plateau 40 thousand to 30 thousand years ago
TLDR
This site, dating from 40,000 to 30,000 years ago, is the highest Paleolithic archaeological site yet identified globally and has yielded an abundant blade tool assemblage, indicating hitherto-unknown capacities for the survival of modern humans who camped in this environment.
Agriculture facilitated permanent human occupation of the Tibetan Plateau after 3600 B.P.
TLDR
Data sets from the northeastern Tibetan Plateau are reported indicating that the first villages were established only by 5200 calendar years before the present, indicating that a novel agropastoral economy facilitated year-round living at higher altitudes since 3600 cal yr B.P.
High-Altitude Rock Shelters and Settlements in an African Alpine Ecosystem: The Bale Mountains National Park, Ethiopia
This first survey of rock shelters and settlements in the Bale Mountains in Ethiopia is a baseline assessment for further research into the settlement history of Africa’s largest alpine highlands.
Permanent human occupation of the central Tibetan Plateau in the early Holocene
TLDR
A reanalysis of the chronology of the Chusang site, located on the central Tibetan Plateau at an elevation of ~4270 meters above sea level, suggests that the site was part of an annual, permanent, preagricultural occupation of the central plateau.
