Final answer:
The earliest throwing spears are associated with Homo heidelbergensis, with the oldest known examples found in Schöningen, Germany dated to around 400,000 years ago, showcasing hafting technology.
Step-by-step explanation:
The earliest throwing spears are associated with the fossil hominin species, Homo heidelbergensis. Notable spear artifacts have been found in Schöningen, Germany, which date back about 400,000 years. These spears showcase an important technological advancement in the form of hafting technology, which entailed affixing stone points to wood, metal, or bone handles, marking an evolutionary step in tool development. Known to have existed alongside early human ancestors and seen as a bridge between Homo erectus and anatomically modern humans, Homo heidelbergensis is recognized for its significant contributions to prehistoric tool technology.
