Pre-Columbian Trans-oceanic Contact Hypotheses
Pre-Columbian transoceanic contact theories, many of which are speculative, propose that visits to the Americas, interactions with the Indigenous peoples of the Americas, or both, were made by people from elsewhere prior to Christopher Columbus's Columbus's first voyage, first voyage to the Caribbean in 1492. Studies between 2004 and 2009 suggest the possibility that the earliest human Settlement of the Americas, migrations to the Americas may have been made by boat from Beringia and travel down the Pacific coast, contemporary with and possibly predating land migrations over the Beringia, Beringia land bridge, which during the glacial period joined what today are Siberia and Alaska. Apart from Norse colonization of North America, Norse contact and settlement, whether transoceanic travel occurred during the historic period, resulting in pre-Columbian contact between the settled American peoples and voyagers from other continents, is vigorously debated. Only a few cases of pre-C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viking Landing
Vikings were seafaring people originally from Scandinavia (present-day Denmark, Norway, and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded, and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean Sea, Mediterranean, North Africa, the Middle East, Greenland, and Vinland (present-day Newfoundland in Canada, North America). In their countries of origin, and some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a whole. The Vikings had a profound impact on the Early Middle Ages, early medieval history of Northern Europe, northern and Eastern Europe, including the political and social development of England (and the English language) and parts of France, and established the embryo of Russia in Kievan Rus'. Expert sailors and navigators of their cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scandinavia
Scandinavia is a subregion#Europe, subregion of northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula (which excludes Denmark but includes a part of northern Finland). In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their Ethnolinguistics, ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east. Most of the population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Easter Island
Easter Island (, ; , ) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is renowned for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts differ on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, a 2007 study provided compelling evidence suggesting their arrival was closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. Land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforestation. By the time of European arrival in 1722, the i ...

Pseudohistory
Pseudohistory is a form of pseudoscholarship that attempts to distort or misrepresent the historical record, often by employing methods resembling those used in scholarly historical research. The related term cryptohistory is applied to pseudohistory derived from the superstitions intrinsic to occultism. Pseudohistory is related to pseudoscience and pseudoarchaeology, and usage of the terms may occasionally overlap. Although pseudohistory comes in many forms, scholars have identified common features in pseudohistorical works. Pseudohistory is almost always motivated by a contemporary political, religious, or personal agenda. It frequently presents sensational claims or a big lie about historical facts which would require unwarranted revision of the historical record. Another hallmark is an underlying premise that scholars have a furtive agenda to suppress the promoter's thesis—a premise commonly corroborated by elaborate conspiracy theories. Works of pseudohistory often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoarchaeology
Pseudoarchaeology (sometimes called fringe or alternative archaeology) consists of attempts to study, interpret, or teach about the subject-matter of archaeology while rejecting, ignoring, or misunderstanding the accepted Scientific method, data-gathering and analytical methods of the discipline.Pseudoarchaeology#FagFed06, Fagan and Feder 2006. p. 720. These pseudoscience, pseudoscientific interpretations involve the use of artifacts, sites or materials to construct scientifically insubstantial theories to strengthen the pseudoarchaeologists' claims. Methods include exaggeration of evidence, dramatic or romanticized conclusions, use of fallacy, fallacious arguments, and fabrication of evidence. There is no unified pseudoarchaeological theory or method, but rather many different interpretations of the past which are jointly at odds with those developed by the scientific community as well as with each other. These include religious philosophies such as creationism or "creation scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fringe Science
Fringe science refers to ideas whose attributes include being highly speculative or relying on premises already Objection (argument), refuted. The chance of ideas rejected by editors and published outside the mainstream being correct is remote. When the general public does not distinguish between science and imitators, it risks exploitation, and in some cases, a "yearning to believe or a generalized suspicion of experts is a very potent incentive to accepting some pseudoscientific claims". The term "fringe science" covers everything from novel hypotheses, which can be tested utilizing the scientific method, to wild ad hoc hypotheses and Mumbo jumbo (phrase), mumbo jumbo. This has resulted in a tendency to dismiss all fringe science as the domain of Pseudoscience, pseudoscientists, hobbyists, and Quackery, quacks. A concept that was once accepted by the mainstream scientific community may become fringe science because of a later evaluation of previous research. For example, focal i ...

Out-of-place Artifact
An out-of-place artifact (OOPArt or oopart) is an artifact of historical, archaeological, or paleontological interest to someone that is claimed to have been found in an unusual context, which someone claims to challenge conventional historical chronology by its presence in that context. Some people might think that those artifacts are too advanced for the technology known to have existed at the time, or that human presence existed at a time before humans are known to have existed. Other people might hypothesize about a contact between different cultures that is hard to account for with conventional historical understanding. This description of archaeological objects is used in fringe science such as cryptozoology, as well as by proponents of ancient astronaut theories, young Earth creationists, and paranormal enthusiasts. It can describe a wide variety of items, from anomalies studied by mainstream science to pseudoarchaeology to objects that have been shown to be hoaxes o ...

Genetic Admixture
Genetic admixture occurs when previously isolated populations interbreed resulting in a population that is descended from multiple sources. It can occur between species, such as with hybrids, or within species, such as when geographically distant individuals migrate to new regions. It results in gene pool that is a mix of the source populations. Examples Climatic cycles facilitate genetic admixture in cold periods and genetic diversification in warm periods. Natural flooding can cause genetic admixture within populations of migrating fish species. Genetic admixture may have an important role for the success of populations that colonise a new area and interbreed with individuals of native populations. Mapping Admixture mapping is a method of gene mapping that uses a population of mixed ancestry (an admixed population) to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynesia
Polynesia ( , ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including Polynesian languages, linguistic relations, Polynesian culture, cultural practices, and Tradition, traditional beliefs. In centuries past, they had a strong shared tradition of sailing and Polynesian navigation, using stars to navigate at night. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the list of islands in the Pacific Ocean, islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Société de Géographie of Paris. By tradition, the islands located in the South Seas, southern Pacific have also often been called the South Sea Islands, and their inhabitants have been called South Sea Islanders. The Hawai ...
