This article spans the prehistory of Portugal from the appearance of the first human populations until the arrival of the Phoenicians in the Iberian Peninsula and the first recorded contacts with other European cultures. Portugal has been inhabited for at least 500,000 years, first by Neanderthals and then by homo sapiens.
Paleolithic
Homo neanderthalensis La Ferrassie 1
In the 200th millennium BC, during the Paleolithic period the Neanderthal Man first entered the Iberian peninsula establishing the Mousterian culture around the 70th millennium BC. In the beginning of the Upper Paleolithic occurred the first large settlement of Europe by Modern Humans, Nomadic Hunter-gathereres coming from the of the Steppes of Central Asia, characterized by the M173 mutation in the Y chromosome, defining them as an Haplogroup R population. These humans would only reach the Iberian Peninsula during the 30th millennium BC. When the Ice Age reached its maximum extent, these modern humans took refuge in Southern Europe, namely in Iberia, and in the steppes of southern Ukraine and Russia coexisting with Neanderthal men. Between the 35th and 33rd millennium BC the Neanderthal Châtelperronian and Modern Human Aurignacian cultures entered the Iberian Peninsula.
In the 30th millennium BC a new wave of Modern Humans made way into the Iberian peninsula, coming from Southern France. Here, this geneticaly homogenous population (caracterized by the M173 mutation in the Y chromosome), would develop the M343 mutation, giving rise to the R1b Haplogroup, still dominant in modern Portuguese and Spanish populations. While Gravettian culture was on its rise, Neanderthal Man's extinction occurred, being today's Portugal their last refuge in the 28th millennium BC.
Between the 20th and 15th millennium BC the Solutrean and Magdalenian cultural periods flourished in Europe. The Pre-historic art in the Valley of Foz Côa (near moder Vila Nova de Foz Côa, in Portugal) is one example of Solutrean cultural period.
In the 10th millennium BC an interstadial deglaciation called Allerød Oscillation occurred weakening the rigorous conditions of the Ice Age. This also ended the Upper Palaeolithic period, beginning the Mesolithic.
The populations sheltered in Iberia, descendants of the Cro-Magnon, given the deglaciation, migrated and recolonized all of Western Europe, thus spreading the R1b Haplogroup populations (still dominat, in variant degrees, from Iberia to Scandinavia).
During this time, the Azilian culture in Southern France and Northern Iberia (to the mouth of the Douro river) is noteworthy, as well as the Muge Culture in the Tagus valley.
