Archaeology News: Monkeys made stone tools 50,000 years ago that were discovered in Brazil - study
Monkeys made stone tools 50,000 years ago that were discovered in Brazil - study
The researchers also state that
they're "confident that the early archeological sites from Brazil may
not be human-derived but may belong to capuchin monkeys."
Stone tools that are estimated to be roughly 50,000 years old were found in Pedra Furada in northeastern Brazil, and that these tools were made by monkeys who lived in that time, according to a study that was first published in November.
The tools found at the sites are characterized "by the use of immediately available raw material," the study says.
The researchers also state that they're "confident that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys." The peer-reviewed study was published in the journal The Holocene.
"We're confident that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys."
Researchers of the study
Capucin monkeys are usually found in the tropical forests in Central and South America, according to Heritage Daily. They are considered to be the smartest New World monkey.
Details of the Pedra Furada
The Pedra Furada contains hundreds of archaeological sites that date back thousands of years.
Researchers in the study had compared stone tools
from the Pedra Furada to modern capuchin-made stone tool deposits, to
which they discovered that the tools from Pedra Furada are consistent
with the capuchin-made stone tools.
Monkeys have used stone tools for hundreds of years
New archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years. Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. In their paper, published in Current Biology, they suggest it raises questions about the origins and spread of tool use in New World monkeys and, controversially perhaps, prompts us to look at whether early human behaviour was influenced by their observations of monkeys using stones as tools. The research was led by Dr Michael Haslam of the University of Oxford, who in previous papers presents archaeological evidence showing that wild macaques in coastal Thailand used stone tools for decades at least to open shellfish and nuts.
