Bow and Arrow’s Rise: New Dating Reveals How It Replaced the Atlatl in North America
A study published this week in the journal PNAS Nexus details a significant shift in ancient North American hunting practices, pinpointing the widespread adoption of the bow and arrow roughly 1,400 years ago. The research, led by Briggs Buchanan of the University of Tulsa in Oklahoma, analyzed 140 radiocarbon dates from preserved organic weapons found across the region, offering a more precise timeline than previously understood.
For decades, archaeologists have debated the timing and manner of the bow and arrow’s introduction to North America. The challenge lies in the perishable nature of the materials used to construct these weapons – wood, sinew and plant fibers – which rarely survive in the archaeological record compared to stone tools. Buchanan and his team overcame this obstacle by focusing on sites known for exceptional preservation, including dry caves, rock shelters, and ice patches, where organic materials were more likely to remain intact.
The study reveals a nuanced pattern of adoption. While the bow and arrow appeared across western North America around the same time, its impact differed significantly between regions. In the southern regions, stretching from northern Mexico to California and the U.S. Southwest, the bow quickly supplanted older technologies like the atlatl – a handheld device used to launch darts with greater force and distance. However, in the north, the atlatl continued to be used alongside the bow and arrow for nearly a thousand years, suggesting a more gradual transition.
Metin Eren, an experimental archaeologist at Kent State University in Ohio, whose work was not directly involved in the PNAS Nexus study, explained the advantages of the bow and arrow. “The bow and arrow offers increased arrow accuracy, distance, velocity, more frequent shots, plus the ability to shoot – and reshoot – from a number of different positions,” Eren said. He noted, however, that the bow also presented trade-offs, requiring more resources to manufacture and maintain, and demanding the use of both hands, potentially compromising a hunter’s ability to wield a shield.
The research suggests the bow and arrow likely originated from a single source and spread rapidly through cultural transmission networks. Researchers acknowledge the possibility of independent invention, citing evidence from other studies indicating that bow-and-arrow technology emerged in multiple contexts throughout history, including the African Middle Stone Age. However, the current archaeological record does not allow for a definitive conclusion on this matter.
Eren’s work focuses on recreating ancient technologies to understand their functionality and limitations. His Experimental Archaeology Laboratory at Kent State University has conducted studies on flint-knapping, butchering efficiency of Clovis points, and ballistics experiments. He emphasized the importance of rigorous scientific methodology in understanding the past, recalling his debunking of an Inuit legend involving knives made of frozen feces, a project that earned him an Ig Nobel prize.
The findings in PNAS Nexus represent a significant refinement of previous estimates that placed the bow and arrow’s arrival in North America much earlier. The study underscores the complex interplay between technological innovation, regional adaptation, and cultural exchange in shaping the history of the continent’s Indigenous populations.
