Sonia Harmand  Sonia Harmand (born in 1974) is a French archaeologist who studies Early Stone Age archaeology and the evolution of stone tool making. She received her undergraduate degree from the University of Paris where she was associated with the "Prehistory and Technology" research unit, which was well known in the field of stone tool analysis. Harmand earned a PhD from Paris Nanterre University, and is a research associate at CNRS, which is the largest French governmental research organization, and Europe's largest fundamental science agency. She worked as a Research Scientist at CNRS for four years before joining Stony Brook University in New York as an associate professor. In 2017 she was named one of the '50 Most Influential French' by the French edition of "Vanity Fair" magazine. In 2011, Harmand discovered the Lomekwi 3 stone tools in the Turkana Basin of Kenya near the town of Lomewki. This discovery was made while Harmand was leading the West Turkana Archaeological Project team along with Jason Lewis. They were both working with Stony Brook University's Turkana Basin Institute at the time. At the Lomekwi 3 site, between 2011 and 2012, there were 149 stone artifacts recovered in total. These artifacts were found at the Lomekwi 3 site which sits above the Toroto Tuff, dated at about 3.32 Ma. The 149 artifacts range from small broken flakes weighing less than 1 kg to anvils and passive elements weighing about 12 kg. All of these tools are evidence of knapped stone tools. Stone tool knapping was previously associated with the genus "Homo". The discovery of stone tools from the Oldevai Gorge in Tanzania dating to about 2.6 Ma brought forth a theory of non-"homo" hominins usage of stone tools since there is only fossil evidence of "homo" from 2.4-2.3 Ma. The tools found at Lomekwi 3 are dated to ≈3.3 Ma which pushes back the evidence of stone tool use by nearly 700,000 years, and further expands the overall archaeological record. Furthermore, these discoveries support the theory of usage of stone tools by non-"homo" hominids. Harmand and other archaeologists and paleoanthropologists suspect "Australophithecines" including: "A. Africanus", "A. Sediba", "A. Garhi", "A. Aethiopicus", and "A. Robustus" to be possible non-"homo" stone tool knappers.
