From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international research team tested if howlers who survived the outbreak had any genetic variations that may have kept them alive. In brown howlers, they found two mutations on immune genes that resulted in amino acid changes in the part of the protein that detects the disease.
Archaeologists at The Australian National University have found the earliest evidence of Indigenous communities cultivating bananas in Australia. The evidence of cultivation and plant management dates back 2,145 years and was found at Wagadagam on the tiny island of Mabuyag in the western Torres Strait. The research is led by a First Australian author. His work makes a statement that goes beyond academia.
Stone fluted points dating back some 8,000 to 7,000 years ago, were discovered on archaeological sites in Manayzah, Yemen and Ad-Dahariz, Oman. Until now, the prehistoric technique of fluting had been uncovered only on 13,000 to 10,000-year-old Native American sites.
A new paper published in the journal PLOS ONE examines fluted projectile points from southern Arabia, detailing production methods and technical aspects that indicate differences in function from the technology of the Americas, despite similarities in form. Findings from experimentation and comparative analysis suggest that highly-skilled, convergent technologies can have varying anthropological implications.
A llama carved from a spondylus shell and a cylindrical laminated gold foil object were the contents of a carved stone box -- an offering -- found at the bottom of Lake Titicaca, according to researchers from Penn State and the Université libre de Bruxelles, Belgium. The offering, found near an island in the lake, was not located where others had found offerings in the past.
Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.
The animal was approximately 10 cm long and lived more than 130 million years ago in what is now the state of Minas Gerais. Its morphology differs from that of all other known lizard species.
Researchers studying lead white pigments on Andean ceremonial drinking vessels known as qeros have found new similarities among these artifacts that could help museums, conservators, historians and scholars better understand the timeline and production of these culturally significant items during the colonial period (1532-1821).
Findings of stone tools move back the first immigration of humans to America at least 15,000 years. This is revealed in a new international study from the University of Copenhagen, where researchers have analysed ancient material from a Mexican mountain cave.
A cave in a remote part of Mexico was visited by humans around 30,000 years ago - 15,000 years earlier than people were previously thought to have reached the Americas. Excavations of Chiquihuite Cave, located in a mountainous area in northern Mexico controlled by drugs cartels, uncovered nearly 2000 stone tools from a small section of the high-altitude cave. Analysis of the sediment in the cave uncovered a new story of the colonisation of the Americas.
