A new study shows that facial differences resulting from population divergence in first Americans is due to the complex interaction of environment and evolution on these populations and sheds light on how human diversification occurred after settlement of the New World.
When it comes to cultural heritage sites, there are few things historians wouldn't do to preserve them for future generations. In particular, stone buildings and sculptures made of plaster and marble are increasingly at risk of damage from air pollution, acid rain and other factors. Researchers now report in ACS Applied Nano Materials a new, calcium-based conservation treatment inspired by nature that overcomes many drawbacks of currently used methods.
What was the role of warfare in Mayan civilization? New evidence from lake sediments around the abandoned city of Witzna indicates that extreme, total warfare was not just an aspect of the late Mayan period, leading to its fall, but a characteristic of intercity rivalry during the peak of Mayan culture. UC Berkeley and Tulane University researchers discovered a thick charcoal layer from a massive, scorched-earth attack on Witzna on May 21, 697 CE (AD).
One of the most exciting discoveries in genome research was that the last common ancestor of all multicellular animals already possessed an extremely complex genome. It has long been unclear whether the arrangement of these genes in the genome also had a certain function. In a recent study, biologists show that not only individual genes but also these gene arrangements in the genome have played a key role in the course of animal evolution.
An analysis of white-tailed deer remains at an archaeological site in Panama revealed signs of 'feasting behavior' associated with this animal among pre-Columbian populations.
In new research published recently in PLOS ONE titled 'Linking late Paleoindian stone tool technologies and populations in North, Central and South America,' scientists from the University of New Mexico led a study in Belize to document the very earliest indigenous stone tool tradition in southern Mesoamerica.
Researchers from the National Museums of Kenya, University of Arkansas, University of Missouri and Duke University have announced the discovery of a tiny monkey that lived in Kenya 4.2 million years ago.
Chaco Canyon, a site that was once central to the lives of precolonial peoples called Anasazi, may not have been able to produce enough food to sustain its estimated population numbers.
The Woodstock Music Festival celebrates its 50th anniversary this summer, and new archaeological research from Binghamton University, State University of New York shows that the iconic event took on a life of its own.
The migration and interaction routes of prehistoric humans throughout the islands of Oceania can be retraced using genetic differences between paper mulberry plants, a tree native to Asia cultivated for fibers to make paper and introduced into the Pacific in prehistoric times to make barkcloth.
