Atapuerca is a World Heritage site with its famous Paleolithic excavations, which can also be visited by prior arrangement. The Gran Dolina is famous, place where the
Homo antecessor (probably H.erectus - experts are not yet sure whether it is a human species of its own) dates to > 850,000 a. A UK remnant was found in the Sima del Elefante that was even older and is estimated at > 1 million a. In the Sima de los Huessos (Bone Cave) 29 complete H.Heidelbergensis skeletons (>400000 a old) were found. (i.e. 80% of all fossil human finds) They are the ancestors of the Neanderthals (200000-40000 a), who in turn lived approx. 40000 a , replaced by H.sapiens (d.s. we), became extinct. To emphasize the importance of this site, it is the cradle of the European natives, here are the testimonies of the first people who immigrated from Africa and therefore they have also been rightly named a UNESCO World Heritage Site. The skeleton finds can be seen in the Museo de la Evolución Humana in Burgos (located in the middle of the old town of Burgos and is a hot tip)
