Indigenous peoples of the Americas

The indigenous peoples of the Americas are the pre-Columbian inhabitants of the Americas, their descendants, and many ethnic groups who identify with those peoples. They are often also referred to as Native Americans, First Nations, Amerigine, and by Christopher Columbus' geographical mistake Indians, modernly disambiguated as the American Indian race, American Indians, Amerindians, Amerinds, or Red Indians.

According to the still-debated New World migration model, a migration of humans from Eurasia to the Americas took place via Beringia, a land bridge which formerly connected the two continents across what is now the Bering Strait. The most recent point at which this migration could have taken place is c. 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleoamericans soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.

Application of the term "Indian" originated with Christopher Columbus, who thought that he had arrived in the East Indies, while seeking Asia. This has served to imagine a kind of racial or cultural unity for the aboriginal peoples of the Americas. Once created, the unified "Indian" was codified in law, religion, and politics. The unitary idea of "Indians" was not originally shared by indigenous peoples, but many over the last two centuries have embraced the identity.

While some indigenous people of the Americas were historically hunter-gatherers, many practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time and work in reshaping, taming, and cultivating the flora indigenous to the Americas. Some societies depended heavily on agriculture while others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and massive empires.

Many parts of the Americas are still populated by indigenous Americans; some countries have sizeable populations, such as Bolivia, Peru, Paraguay, Mexico, Guatemala, Colombia, and Ecuador. At least a thousand different indigenous languages are spoken in the Americas and some like Quechua, Guaraní, Mayan languages, and Nahuatl count their speakers in millions. Most indigenous peoples have largely adopted the lifestyle of the western world, but many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Some indigenous peoples still live in relative isolation from Europeanized society, and a few are still counted as uncontacted peoples.

History

Original migrations to the Americas

Scholars who follow the Bering Strait theory agree that most indigenous peoples of the Americas descended from people who probably migrated from Siberia across the Bering Strait, anywhere between 9,000 and 50,000 years ago. The time frame and exact routes are still matters of debate, and the model faces continuous challenges. A 2006 study (to be published in Journal of California and Great Basin Anthropology) reports new DNA-based research that links DNA retrieved from a 10,000-year-old fossilized tooth from an Alaskan island with specific coastal tribes in Tierra del Fuego, Ecuador, Mexico, and California. Unique DNA markers found in the fossilized tooth were found only in these specific coastal tribes, and were not comparable to markers found in any other indigenous peoples in the Americas. This finding lends substantial credence to a migration theory that at least one set of early peoples moved south along the west coast of the Americas in boats. However, these results may be ambiguous, as there are other issues with DNA research and biological and cultural affiliation.

One result of these waves of migration is that large groups of peoples with similar languages and perhaps physical characteristics as well, moved into various geographic areas of North, and then Central and South America. While these peoples have traditionally remained primarily loyal to their individual tribes, ethnologists have variously sought to group the myriad of tribes into larger entities which reflect common geographic origins, linguistic similarities, and lifestyles.

Remnants of a human settlement in Monte Verde, Chile dated to 12,500 years B.P. (another layer at Monte Verde has been tentatively dated to 33,000–35,000 years B.P.) suggests that southern Chile was settled by peoples who entered the Americas before the peoples associated with the Bering Strait migrations. It is suggested that a coastal route via canoes could have allowed rapid migration into the Americas.

The traditional view of a relatively recent migration has also been challenged by older findings of human remains in South America; some dating to perhaps even 30,000 years old or more. Some recent finds (notably the Luzia Woman in Lagoa Santa, Brazil) are claimed to be morphologically distinct from most Asians and are more similar to Africans, Melanesians and Australian Aborigines. These American Aborigines would have been later displaced or absorbed by the Siberian immigrants. The distinctive Fuegian natives of Tierra del Fuego, the southernmost tip of the American continent, are speculated to be partial remnants of those Aboriginal populations. These early immigrants would have either crossed the ocean by boat or traveled north along the Asian coast and entered America through the Northwest, well before the Siberian waves. This theory is presently viewed by many scholars as conjecture, as many areas along the proposed routes now lie underwater, making research difficult. Some scholars believe the earliest forensic evidence for early populations appears to more closely resemble Southeast Asians and Pacific Islanders, and not those of Northeast Asia.

Scholars' estimates of the total population of the Americas before European contact vary enormously, from a low of 10 million to a high of 112 million. Some authors see ideological underpinnings in this population debate. For example, Robert Royal writes that "estimates of pre-Columbian population figures have become heavily politicized with scholars who are particularly critical of Europe and/or Western civilization often favoring wildly higher figures." Some scholars believe that most of the indigenous population resided in Mesoamerica and South America, with approximately 10 percent residing in North America, prior to European colonization.

The Solutrean hypothesis suggests an early European migration into the Americas and that stone tool technology of the Solutrean culture in prehistoric Europe may have later influenced the development of the Clovis tool-making culture in the Americas. Some of its key proponents include Dr. Dennis Stanford of the Smithsonian Institution and Dr. Bruce Bradley of the University of Exeter. In this hypothesis, peoples associated with the Solutrean culture migrated from Ice Age Europe to North America, bringing their methods of making stone tools with them and providing the basis for later Clovis technology found throughout North America. The hypothesis rests upon particular similarities in Solutrean and Clovis toolmaking styles, and the fact that no predecessors of Clovis technology have been found in Eastern Asia, Siberia or Beringia, areas from which or through which early Americans are thought to have migrated.

American Indian creation legends tell of a variety of originations of their respective peoples. Some were "always there" or were created by gods or animals, some migrated from a specified compass point, and others came from "across the ocean".

Vine Deloria, Jr., author and Nakota activist, cites some of the oral histories that claim an in situ origin in his book Red Earth, White Lies, rejecting the Bering Strait land bridge route. Deloria takes a Young Earth position, arguing that Native Americans actually originated in the Americas.

Recent genetic research

An article in the American Journal of Human Genetics states "Our results strongly support the hypothesis that haplogroup X, together with the other four main mtDNA haplogroups, was part of the gene pool of a single Native American founding population; therefore they do not support models that propose haplogroup-independent migrations, such as the migration from Europe posed by the Solutrean hypothesis." The National Geographic Genographic Project identified haplogroup Q-M242 as the YDNA male ancestor of the "Siberian Clan," some of whom remained in Asia, but that today "almost all Native Americans are descendants from this man."

European colonization

The European colonization of the Americas forever changed the lives, bloodlines and cultures of the peoples of the continent. The population history of American indigenous peoples postulates that disease exposure, displacement, and warfare diminished populations, with the first the most significant cause. The first indigenous group encountered by Columbus were the 250,000 Tainos of Hispaniola who were the dominant culture in the Greater Antilles and the Bahamas. In thirty years, about 70% of the Tainos died. Enslaved, forced to labour in the mines, mistreated, the Tainos began to adopt suicidal behaviors, with women aborting or killing their infants, men jumping from the cliffs or ingesting manioc, a violent poison. They had no immunity to European diseases, so outbreaks of measles and smallpox ravaged their population.

The Laws of Burgos, 1512-1513 were the first codified set of laws governing the behavior of Spanish settlers in America, particularly with regards to native Indians. They forbade the maltreatment of natives, and endorsed their conversion to Catholicism.

Reasons for the decline of the Native American populations are variously theorized to be from diseases, conflicts with Europeans, and conflicts among warring tribes. Scholars now believe that, among the various contributing factors, epidemic disease was the overwhelming cause of the population decline of the American natives. After first contacts with Europeans and Africans, some believe that the death of 90 to 95% of the native population of the New World was caused by Old World diseases. Half the native population of Hispaniola in 1518 was killed by smallpox. Within a few years smallpox killed between 60% and 90% of the Inca population, with other waves of European disease weakening them further. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, measles in 1618—all ravaged the remains of Inca culture. Smallpox had killed millions of native inhabitants of Mexico. Unintentionally introduced at Veracruz with the arrival of Panfilo de Narvaez on April 23, 1520, smallpox ravaged Mexico in the 1520s, killing 150,000 in Tenochtitlán alone, including the emperor, and was credited with the victory of Cortes over the Aztec empire at Tenochtitlan (present-day Mexico City) in 1521.

Over the centuries, the Europeans had developed high degrees of immunity to these diseases, while the Native Americans had no such immunity. Europeans had been ravaged in their own turn by such diseases as bubonic plague and Asian flu that moved west from Asia to Europe. In addition, when they went to some territories, such as Africa and Asia, they were more vulnerable to malaria.

In 1633 in Plymouth, Massachusetts, the Native Americans were exposed to smallpox because of contact with Europeans. As it had done elsewhere, the virus wiped out entire population groups of Native Americans. It reached Lake Ontario in 1636, and the lands of the Iroquois by 1679. During the 1770s, smallpox killed at least 30% of the West Coast Native Americans. Smallpox epidemics in 1780–1782 and 1837–1838 brought devastation and drastic population depletion among the Plain Indians. In 1832, the federal government of the United States established a smallpox vaccination program for Native Americans (The Indian Vaccination Act of 1832).

In Brazil the indigenous population has declined from a pre-Columbian high of an estimated 3 million to some 300,000 in 1997.

Later explorations of the Caribbean led to the discovery of the Aruak peoples of the Lesser Antilles. The culture was extinct by 1650. Only 500 had survived by the year 1550, though the bloodlines continued through the modern populace. In Amazonia, indigenous societies weathered centuries of colonization.

The Spaniards and other Europeans brought horses to the Americas. Some of these animals escaped and began to breed and increase their numbers in the wild. The re-introduction of the horse had a profound impact on Native American culture in the Great Plains of North America and of Patagonia in South America. By domesticating horses, some tribes had great success: they expanded their territories, exchanged many goods with neighboring tribes, and more easily captured game, especially bison.

Agriculture

About 4,000 years ago, the Archaic Native American cultures began practicing farming. Technology had advanced to the point that pottery was becoming common, and the small-scale felling of trees became feasible. Concurrently, the Archaic Indians began using fire in a widespread manner. Intentional burning of vegetation was used to mimic the effects of natural fires that tended to clear forest understories. It made travel easier and facilitated the growth of herbs and berry-producing plants, which were important for both food and medicines.

Over the course of thousands of years, American indigenous peoples domesticated, bred and cultivated a large array of plant species. These species now constitute 50–60% of all crops in cultivation worldwide. In certain cases, the indigenous peoples developed entirely new species and strains through artificial selection, as was the case in the domestication and breeding of maize from wild teosinte grasses in the valleys of southern Mexico. Numerous such agricultural products retain native names in the English and Spanish lexicons.

In the Mississippi River valley, Europeans noted Native Americans' managed groves of nut and fruit trees as orchards, not far from villages and towns, in addition to their gardens and agricultural fields. Wildlife competition could be reduced by understory burning. Further away, prescribed burning would have been used in forest and prairie areas.

Many crops first domesticated by indigenous Americans are now produced and/or used globally. Chief among these is maize or "corn", arguably the most important crop in the world. Other significant crops include cassava, chia, squash (pumpkins, zucchini, marrow, acorn squash, butternut squash), the pinto bean, Phaseolus beans including most common beans, tepary beans and lima beans, tomato, potatoes, avocados, peanuts, cocoa beans (used to make chocolate), vanilla, strawberries, pineapples, Peppers (species and varieties of Capsicum, including bell peppers, jalapeños, paprika and chili peppers) sunflower seeds, rubber, brazilwood, chicle, tobacco, coca, manioc and some species of cotton.
