B. Wooden spear-throwing devices
C. Composite tools made from bone, wood, and stone
D. Bifacial hand axes and cleavers

Answer :

Final answer:

Acheulean tools characterize the use of bifacial hand axes and cleavers. These sophisticated tools, superior to previous Oldowan tools, were modified on both sides, marking an increase in cognitive ability and motor skills needed for creating such tools. The Acheulean tools are thinner, sharper, and useful for tasks like cutting and scraping.

Explanation:

Acheulean tools, which were in dominance till about 250,000 years ago, are characterized by bifacial hand axes and cleavers. Bifarce in the context of Acheulean tools implies that these tools were modified on both sides to result in a symmetric tool with two faces. They were created from large flakes knocked off cleverly from stone cores, with the aid of a more delicate technique than merely colliding two rocks. This method of creation required grander motor skills and cognitive capability from tool makers, marking a milestone in human development.

Acheulean tools present an upgrade to the Oldowan tools characterized by a more intricate, teardrop shape, leading to a sharper, and more effective means for cutting, chopping, and scraping tasks. They were such an advancement from earlier tools that they warranted a distinct name, borrowed from Saint-Acheul where the tools were first uncovered in the 19th century. Compared to former tools, Acheulean tools were relatively thinner and sharper, adding to their efficacy.
