A skull fragment and shin bone suggest that early modern humans might have passed through southeast Asia earlier than thought Archaeologists have uncovered two new bone fragments in a cave in northern Laos, suggesting that Homo sapiens wandered southeast Asia up to 86,000 years ago. The findings, published this week in Nature Communications1, indicate that humans migrated through the area earlier than previously thought. Over more than a decade, excavations in the Tam Pà Ling cave have uncovered seven bone fragments sandwiched between layers of clay. Laura Shackelford, an anthropologist at the University of Illinois Urbana–Champaign, and her colleagues have regularly had to hike through sticky tropical heat to reach the mountain-top cave.

A new study led by Prof. DING Lin from the Institute of Tibetan Plateau Research (ITP) of the Chinese Academy of Sciences has revealed the evolution of the Central Tibetan Valley, which may shed light on the formation of Tibetan Plateau. The findings were published in Science Advances on Feb. 10. The growth of Tibetan Plateau has attracted much attention since the 19th Century for its influences on the regional and global climate and biodiversity. Previous researches indicate that around 60 million years ago (mya), before the collision of the Indian and Eurasian plates, a wet and low elevation Valley system existed between the high Gangdese Mountains on the southern margin of Eurasia and the Central Watershed Mountains in the north. The range of the central Tibetan Valley (whi...
