Final answer:
The terms bone shaft wrench and blades struck from a chert core refer to the advanced stone and bone tools from prehistoric human technologies, specifically within the Acheulean and Upper Paleolithic blade tool industries.
Step-by-step explanation:
Artifacts like a bone shaft wrench and blades struck from a chert core are indicative of the sophisticated stone tool technologies developed by prehistoric humans. These innovations reflect a range of stone tool industries including the Acheulean tools, known for their hand-axes made by careful chipping of stones to create a symmetric, teardrop-shaped implement, which was a significant improvement over the cruder Oldowan tools. During the Upper Paleolithic era, humans transitioned to the blade tool industry, manufacturing tools such as narrow-bladed flints or burins and becoming proficient in crafting tools from various materials, such as bone and antler.
