NeanderthalNeanderthals (niˈændə(r)ˌtɑːl,neɪ-,-ˌθɑːl; Homo neanderthalensis or H. sapiens neanderthalensis), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. The reasons for Neanderthal extinction are disputed. Theories for their extinction include demographic factors such as small population size and inbreeding, competitive replacement, interbreeding and assimilation with modern humans, climate change, disease, or a combination of these factors.
DouroThe Douro (UKˈdʊərəʊ,_ˈdʊəruː, USˈdɔːruː,_ˈdɔːrəʊ,_ˈdəʊru, ˈdo(w)ɾu; Duero ˈdweɾo; Mirandese: Douro [ˈdowɾʊ]; Durius) is the highest-flow river of the Iberian Peninsula. It rises near Duruelo de la Sierra in the Spanish province of Soria, meanders south briefly then flows generally west through the northern part of the Meseta Central in Castile and León into northern Portugal. Its most plentiful tributary (carrying a larger discharge than the Douro at their meeting) is the right-bank Esla river.
Base levelIn geology and geomorphology a base level is the lower limit for an erosion process. The modern term was introduced by John Wesley Powell in 1875. The term was subsequently appropriated by William Morris Davis who used it in his cycle of erosion theory. The "ultimate base level" is the plane that results from projection of the sea level under landmasses. It is to this base level that topography tends to approach due to erosion, eventually forming a peneplain close to the end of a cycle of erosion.
IberiansThe Iberians (Hibērī, from Ἴβηρες, Iberes) were an ancient people settled in the eastern and southern coasts of the Iberian peninsula, at least from the 6th century BC. They are described in Greek and Roman sources (among others, by Hecataeus of Miletus, Avienius, Herodotus and Strabo). Roman sources also use the term Hispani to refer to the Iberians. The term Iberian, as used by the ancient authors, had two distinct meanings.

PyreneesThe Pyrenees (ˈpɪrᵻniːz; Pirineos piɾiˈneos; Pyrénées piʁene; Pirineu piɾiˈnɛw; Pirinioak piɾini.o.ak; Pirenèus piɾeˈnɛws; Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between.
CantabriaCantabria (kænˈteɪbriə, also UK-ˈtæb-, kanˈtaβɾja ) is an autonomous community and province in northern Spain with Santander as its capital city.
