It is often argued that complex projectile technology emerged and spread out of Africa with Homo sapiens, but this hypothesis remains untested. Recent research shows certain tip fractures and usewear/residues on stone points may be diagnostic of high-speed projectile impacts, facilitating identification of early complex projectiles. This project aims to use controlled ballistic experiments to generate diagnostic markers of high-speed impacts, test these against ethnographic collections, and analyse archaeological points on four continents. The should provide significant benefits in understanding the origins of complex projectiles, their role in human dispersal, inter-species competition and reasons for early appearance in Australia.

人们经常认为，复杂的投射技术是随着智人从非洲出现并传播出去的，但这一假设尚未得到证实。最近的研究表明，某些尖端断裂和石尖上的使用磨损/残留物可能是高速弹丸撞击的诊断，有助于早期复杂弹丸的识别。该项目旨在使用受控弹道实验来生成高速撞击的诊断标记，将其与人种学收藏品进行测试，并分析四个考古点
