2.9 million-year-old tools found in Kenya stir up a 'fascinating whodunnit'

The stone tools could likely be the oldest evidence of Stone Age innovation.

An international team of archaeologists recently uncovered some of the oldest stone tools ever found. The ancient tools, discovered along the banks of Lake Victoria in Kenya, are likely the oldest evidence of both an important Stone Age innovation called the Oldowan toolkit and of hominins consuming very large animals. The findings were published on February 9 in the journal Science. 
The Oldowan toolkit includes three types of stone tools: hammerstones for hitting other rocks or creating tools that pound, cores that are angular or oval shaped and split off pieces of material, and flakes used as a cutting or scraping edge.
