Australian researchers have used hepatitis B virus genome sequences to deduce that the mainland Aboriginal population separated from other early humans at least 59,000 years ago.
When UC Santa Barbara geology professor emeritus James Kennett and colleagues set out years ago to examine signs of a major cosmic impact that occurred toward the end of the Pleistocene epoch, little did they know just how far-reaching the projected climatic effect would be.
The authors of the study have developed tools that link Life-Cycle Analysis (LCA) and Building Information Modeling (BIM) software so that environmental-impact reduction criteria can be integrated into projects from the moment of their first design.
By re-dating giant ground sloth remains found in the Argentinian Pampas region using more advanced technology, scientists say they have provided evidence that humans hunted and butchered this animal near a swamp during the end of the Pleistocene.
A mass sacrifice at a 15th century archaeological site in Peru saw the ritual killing of over 140 children and over 200 llamas, according to a study released March 6, 2019 in the open access journal PLOS ONE by Gabriel Prieto of the National University of Trujillo, Peru and colleagues. This is the largest known mass sacrifice of children -- and of llamas -- in the New World.
Fossilized bones that appear to have been digested by crocodiles in the Cayman Islands have revealed three new species and subspecies of mammal that roamed the island more than 300 years ago.
Washington State University archaeologists have discovered the oldest tattooing artifact in western North America. The tool was made around 2,000 years ago by the Ancestral Pueblo people of the Basketmaker II period in what is now southeastern Utah.
A team of paleontologists led by Virginia Tech's Michelle Stocker and Sterling Nesbitt of the Department of Geosciences have identified fossil fragments of what are thought to be the oldest known frogs in North America.
Some 27,000 years ago in central Belize, a giant sloth was thirsty. It eventually found water in a deep sinkhole, but it was the creature's last drink. A new analysis of its tooth offers insight into the landscape it inhabited and what it ate its last year of life.
High-tech radar and laser scans have uncovered a hidden military traverse underneath the infamous Alcatraz penitentiary, according to research led by faculty at Binghamton University, State University of New York.
