History of EuropeThe history of Europe is traditionally divided into four time periods: prehistoric Europe (prior to about 800 BC), classical antiquity (800 BC to AD 500), the Middle Ages (AD 500 to AD 1500), and the modern era (since AD 1500). The first early European modern humans appear in the fossil record about 48,000 years ago, during the Paleolithic Era. Settled agriculture marked the Neolithic Era, which spread slowly across Europe from southeast to the north and west.
Portuguese peopleThe Portuguese people (Portugueses - masculine - or Portuguesas) are a Romance-speaking ethnic group and nation indigenous to Portugal, a country in the west of the Iberian Peninsula in the south-west of Europe, who share a common culture, ancestry and language. The Portuguese people's heritage largely derives from the proto-Celtic/proto-Italic Indo-European (Lusitanians, Conii) and Celtic peoples (Gallaecians, Turduli and Celtici), who were later Romanized after the conquest of the region by the ancient Romans.
HaplogroupA haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the ἁπλοῦς, haploûs, "onefold, simple" and group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes.
French peopleThe French people (Français) are a nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily descended from Gauls (including the Belgae), Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day.
Domestication of the horseHow and when horses became domesticated has been disputed. Although horses appeared in Paleolithic cave art as early as 30,000 BCE, these were wild horses and were probably hunted for meat. The clearest evidence of early use of the horse as a means of transport is from chariot burials dated c. 2000 BCE. However, an increasing amount of evidence began to support the hypothesis that horses were domesticated in the Eurasian Steppes in approximately 3500 BCE.
