What are the three Lower Paleolithic tool traditions mentioned?

The three Lower Paleolithic tool traditions recognized in anthropology are the Oldowan, Acheulean, and Zhoukoudian.

The Oldowan is the earliest known stone tool industry, characterized by simple tools typically made from flaked rocks. This tradition is significant because it marks the beginning of the use of tools by early hominins, dating back to approximately 2.6 million years ago.

The Acheulean follows the Oldowan and is well-known for its bifacial tools, especially hand axes, which show advanced knapping techniques and a better understanding of tool-making compared to earlier traditions. This culture began around 1.76 million years ago and is associated with Homo erectus and early Homo heidelbergensis.

Zhoukoudian refers to a significant archaeological site in China where hominin fossils and tools have been found, particularly those associated with the Peking Man. Tools found in this context generally belong to the Acheulean tradition, indicating the geographic spread and technological similarities across different regions.

The other options present tool traditions and periods that either do not align chronologically or are misclassified. The Mesolithic and Neolithic periods, for instance, occur after the Lower Paleolithic and are associated with different types of tools
