The Atapuerca project started in 1978, with a number of excavations and findings in the province of Burgos, Spain. The team concentrates more than 150 multi-disciplinary specialists who have been working in the archeological site of Atapuerca since then. In 2007, they discovered the first human bones of the Homo Antecessor species. The discovery of this jawbone confirms the presence of humans in the Sierra de Atapuerca more than 1,200,000 years ago, the oldest period known in Europe to date. These findings were published in Nature in 2008 and presented to the international scientific community. In 2010 the Museum of Human Evolution was founded, with great social and economic impact in the region.
