**Groundbreaking Study Reveals Adoption Timeline of Bow and Arrow in North America** A recent paper published in the *PNAS Nexus* journal has shed light on the adoption of the bow and arrow in North America, a significant development that marked the end of the dart and atlatl era. According to the study, the transition occurred approximately 1,400 years ago. However, the adoption process was not uniform across the continent. In southern regions, the bow and arrow was adopted almost immediately, replacing the dart and atlatl as the primary hunting tool. Conversely, in northern areas, the bow and arrow was initially adopted as a complement to the existing toolkit, gradually replacing the atlatl and dart over a period of approximately 1,000 years. This distinction highlights the varying cultural and environmental contexts that influenced the adoption of new technologies. **Experimental Archaeology Laboratory at Kent State University** The study was conducted by Metin Eren and his team at the Experimental Archaeology Laboratory at Kent State University in Ohio. Eren's laboratory is dedicated to reverse-engineering ancient technologies, including stone tools, ceramics, metal, butchery, and textiles. The team's research has spanned a wide range of topics, from the properties of flint-knapping to the butchering efficiency of Clovis points. Eren's work has garnered attention for its innovative approach to understanding ancient technologies. In 2019, he gained international recognition for his study on the use of frozen feces to create rudimentary knives, which was awarded an Ig Nobel prize. Despite the attention-grabbing nature of some of his research, Eren emphasizes that his work is grounded in serious scientific inquiry, rather than entertainment. **Hands-on Approach to Experimental Archaeology** The Experimental Archaeology Laboratory at Kent State University offers students the opportunity to engage in hands-on research, including throwing point-tipped spears at a hunting target using an atlatl or spear-thrower. The atlatl is a handheld device that employs leverage to launch a dart or spear, with various designs developed by ancient cultures around the world. By experimenting with these technologies, researchers can gain a deeper understanding of the tools and techniques used by our ancestors.
