A University of Calgary archaeologist who is one of the few researchers in the world studying the material culture of human beings' closest living relatives – the great apes – is joining his colleagues in creating a new discipline devoted to the history of tool use in all primate species in order to better understand human evolution.
Julio Mercader, holder of the Canada Research Chair in Tropical Archaeology in the U of C's Department of Archaeology, is the only Canadian author of a new paper titled "Primate archaeology" published this week in the prestigious scientific journal Nature. Mercader is one of 18 co-authors from universities including Cambridge, Rutgers, Kyoto University and schools in Spain, Italy and France. They argue that recent discoveries of tool use by a wide variety of wild primates and archaeological evidence of chimpanzees using stone tools for thousands of years is forcing experts to re-think the traditional dividing lines between humans and other primate species as well as the belief that tool use is the exclusive domain of the genus Homo. The researchers advocate for a new inter-disciplinary field of primate archaeology to examine tool use by primates in a long-term, evolutionary context. The paper is the result of the international symposium "Palaeoanthropology meets Primatology" held on Oct. 18, 2008 at Cambridge.
"There is a need for systematic collaboration between diverse research programs to understand the broader questions in human evolution and primatology," Mercader says. "For example, few archaeologists have seen a wild primate use a tool, while few primatologists have taken part in archaeological excavations," he explains.
Mercader was the lead author of a team that laid the foundations of the emerging discipline of chimpanzee archaeology in two previously-published papers in Science and the Proceedings of the National Academy of Sciences (PNAS). He is the archaeologist who uncovered the first prehistoric evidence of chimpanzee technology in 2007 — a 4,300-year-old nut-cracking site in the rainforests of Côte D'Ivoire, West Africa that provides proof of a long-standing chimpanzee "stone age" that likely emerged independently of influence from humans.
One of the United States' top Syro-Palestinian archaeologists, Bill Dever, has been calling for increased interdisciplinary cooperation for several years.
His book What Did the Biblical Writers Know and When Did They Know It?: What Archaeology Can Tell Us About the Reality of Ancient Israel makes an excellent case for a newer approach.
