Denisovans Expanded Their Range to Southwest China, Revealed by Proteomic Analysis

A large-scale screening of over 60,000 bone fragments from Bianfu Cave in western Yunnan used ZooMS and proteomics to identify three Denisovan bones (two parietals and a proximal radius) and two Denisovan teeth, dating to about 167–134 thousand years ago. This makes Bianfu Cave a Denisovan locality with the most abundant remains outside Denisova Cave and provides new postcranial data, refining our understanding of Denisovan distribution, morphology, and adaptive biology.

Ancient Bone Needles Reveal Ice Age Survival Tactics in Wyoming

Archaeologists in Wyoming have discovered 32 bone needle fragments at the La Prele site, revealing that ancient Americans used tools made from the bones of small carnivores like red foxes and extinct American cheetahs to survive the Ice Age. This finding, published in PLOS ONE, challenges previous assumptions that such tools were made from larger animals like bison or mammoths. The site, associated with the Clovis culture, provides insights into the lives of some of North America's earliest inhabitants.

"Ancient Bone Collagen Sheds Light on Extinction of North America's Large Mammals"

Researchers have used a novel technique called ZooMS to analyze fragmented bone material from the Smithsonian Museum, uncovering new clues about the extinction of North America's megafauna 50,000 years ago. This method, which identifies species through collagen protein sequences, has shown promising results, potentially offering new insights into the longstanding debate over whether human activity or climate change led to these extinctions.
