What new tool types are introduced during the Middle Pleistocene, and who are they associated with?

A. Handaxes - Homo habilis
B. Acheulean tools - Homo erectus
C. Blades - Homo sapiens
D. Oldowan tools - Homo naledi

Answer :

Final answer:

The Middle Pleistocene saw the introduction of Acheulean tools, created by Homo erectus, which were hand-axes that showed significant improvement in sophistication over the older Oldowan tools. The Homo neanderthalensis was associated with the production of smaller hand-axes, known as Mousterian tools, in the Middle Paleolithic. By the Upper Paleolithic era, Homo sapiens had started creating more complex tools from various materials, including the introduction of blades.

Explanation:

The Middle Pleistocene introduced the Acheulean tools and they were associated primarily with Homo erectus. These tools were teardrop-shaped hand-axes made by carefully chipping away smaller flakes of the stone core, resulting in thinner, sharper, and more efficient tools than their Oldowan predecessors. These hand-axes were so much more sophisticated that they received their unique name from Saint-Acheul, the French site where they were first discovered.

Later in the Middle Paleolithic, Homo neanderthalensis and the Mousterian tool industry evolved. These tools were smaller hand-axes made from stone flakes prepared in a way that they themselves could be used as small knives for cutting meat, scraping leather, and functioning as spearheads.

By the Upper Paleolithic, Homo sapiens began assembling a more complex tool kit with a variety of materials including antler, ivory, and bone. They also shifted from manufacturing round flakes to the creation of blade tools, also known as the blade tool industry. These blades are stone flakes that are long, thin, flat and have a sharp edge, much longer cutting edge than flakes which are more efficient than older technologies.
