Paleo-Indians, Paleoindians or Paleoamericans is a classification term given by scholars to the first peoples who entered, and subsequently inhabited, the Americas during the final glacial episodes of the late Pleistocene period. The prefix "paleo-" comes from the Greek adjective palaios (παλαιός), meaning "old" or "ancient". The term "Paleo-Indians" applies specifically to the lithic period in the Western Hemisphere and is distinct from the term "Paleolithic".
Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land-and-ice bridge (Beringia). This bridge existed from 45,000–12,000 BCE (47,000–14,000 BP). Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From c. 16,500 – c. 13,500 BCE (c. 18,500 – c. 15,500 BP), ice-free corridors developed along the Pacific coast and valleys of North America. This allowed animals, followed by humans, to migrate south into the interior of the continent. The people went on foot or used primitive boats along the coastline. The precise dates and routes of the peopling of the New World remain subjects of ongoing debate.
Stone tools, particularly projectile points and scrapers, are the primary evidence of the earliest human activity in the Americas. Archaeologists and anthropologists use surviving crafted lithic flaked tools to classify cultural periods. Scientific evidence links Indigenous Americans to eastern Siberian populations. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. There is evidence for at least two separate migrations. From 8000–7000 BCE (10,000–9,000 BP) the climate stabilized, leading to a rise in population and lithic technology advances, resulting in more sedentary lifestyle.

The Lithic peoples or Paleo-Indians are the earliest known settlers of the Americas. The period's name derives from the appearance of "lithic flaked" stone tools.
The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, are subject to ongoing research and discussion. The traditional theory has been that these early migrants moved into Beringia between eastern Siberia and present-day Alaska 17,000 years ago, when sea levels were significantly lowered due to the Quaternary glaciation. These people are believed to have followed herds of now-extinct pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America. Evidence of the latter would since have been covered by a sea level rise of hundreds of meters following the last ice age.
Archaeologists contend that Paleo-Indians migrated out of Beringia (western Alaska), ranging from c. 40,000 – c. 16,500 years ago. This time range is a source of debate and promises to continue as such for years to come. The few agreements achieved to date are the origin from Central Asia, with widespread habitation of the Americas during the end of the last glacial period, or more specifically what is known as the late glacial maximum, around 16,000–13,000 years before present. However, alternative theories about the origins of Paleoindians exist, including migration from Europe.
Sites in Alaska (East Beringia) are where some of the earliest evidence has been found of Paleo-Indians, followed by archaeological sites in northern British Columbia, western Alberta and the Old Crow Flats region in the Yukon. The Paleo-Indian would eventually flourish all over the Americas. These peoples were spread over a wide geographical area; thus there were regional variations in lifestyles. However, all the individual groups shared a common style of stone tool production, making knapping styles and progress identifiable. This early Paleo-Indian period lithic reduction tool adaptations have been found across the Americas, utilized by highly mobile bands consisting of approximately 20 to 60 members of an extended family. Food would have been plentiful during the few warm months of the year. Lakes and rivers were teeming with many species of fish, birds and aquatic mammals. Nuts, berries and edible roots could be found in the forests and marshes. The fall would have been a busy time because foodstuffs would have to be stored and clothing made ready for the winter. During the winter, coastal fishing groups moved inland to hunt and trap fresh food and furs.
Late ice age climatic changes caused plant communities and animal populations to change. Groups moved from place to place as preferred resources were depleted and new supplies were sought. Small bands utilized hunting and gathering during the spring and summer months, then broke into smaller direct family groups for the fall and winter. Family groups moved every 3–6 days, possibly traveling up to 360 km (220 mi) a year. Diets were often sustaining and rich in protein due to successful hunting. Clothing was made from a variety of animal hides that were also used for shelter construction. During much of the Early and Middle Paleo-Indian periods, inland bands are thought to have subsisted primarily through hunting now-extinct megafauna. Large Pleistocene mammals were the giant beaver, steppe wisent, musk ox, mastodons, woolly mammoths and ancient reindeer (early caribou).
The Clovis culture, appearing around 11,500 BCE (c. 13,500 BP), undoubtedly did not rely exclusively on megafauna for subsistence. Instead, they employed a mixed foraging strategy that included smaller terrestrial game, aquatic animals, and a variety of flora. Paleo-Indian groups were efficient hunters and carried a variety of tools. These included highly efficient fluted style spear points, as well as microblades used for butchering and hide processing. Projectile points and hammerstones made from many sources are found traded or moved to new locations. Stone tools were traded and/or left behind from North Dakota and Northwest Territories, to Montana and Wyoming. Trade routes also have been found from the British Columbia Interior to the coast of California.
The glaciers that covered the northern half of the continent began to gradually melt, exposing new land for occupation around 17,500–14,500 years ago. At the same time as this was occurring, worldwide extinctions among the large mammals began. In North America, camels and horses eventually died off, the latter not to reappear on the continent until the Spanish reintroduced the species near the end of the 15th century CE. As the Quaternary extinction event was happening, the Late Paleo-Indians would have relied more on other means of subsistence.
From c. 10,500 – c. 9,500 BCE (c. 12,500 – c. 11,500 BP), the broad-spectrum big game hunters of the great plains began to focus on a single animal species: the bison (an early cousin of the American bison). The earliest known of these bison-oriented hunting traditions is the Folsom tradition. Folsom peoples traveled in small family groups for most of the year, returning yearly to the same springs and other favored locations on higher ground. There they would camp for a few days, perhaps erecting a temporary shelter, making and/or repairing some stone tools, or processing some meat, then moving on. Paleo-Indians were not numerous and population densities were quite low.
Paleo-Indians are generally classified by lithic reduction or lithic core "styles" and by regional adaptations. Lithic technology fluted spear points, like other spear points, are collectively called projectile points. The projectiles are constructed from chipped stones that have a long groove called a "flute". The spear points would typically be made by chipping a single flake from each side of the point. The point was then tied onto a spear of wood or bone. As the environment changed due to the ice age ending around 17–13Ka BP on short, and around 25–27Ka BP on the long, many animals migrated overland to take advantage of the new sources of food. Humans following these animals, such as bison, mammoth and mastodon, thus gained the name big-game hunters. Pacific coastal groups of the period would have relied on fishing as the prime source of sustenance.
Archaeologists are piecing together evidence that the earliest human settlements in North America were thousands of years before the appearance of the current Paleo-Indian time frame (before the late glacial maximum 20,000 plus years ago). Evidence indicates that people were living as far east as northern Yukon, in the glacier-free zone called Beringia before 30,000 BCE (32,000 BP). Until recently, it was generally believed that the first Paleo-Indian people to arrive in North America belonged to the Clovis culture. This archaeological phase was named after the town of Clovis, New Mexico, where in 1936 unique Clovis points were found in situ at the site of Blackwater Draw, where they were directly associated with the bones of Pleistocene animals.
Recent data from a series of archaeological sites throughout the Americas suggest that Clovis (thus the "Paleo-Indians") time range should be re-examined. In particular, sites located near Cactus Hill in Virginia, Meadowcroft Rockshelter in Pennsylvania, Bear Spirit Mountain in West Virginia,Monte Verde in Chile, Topper in South Carolina, and Quintana Roo in Mexico have generated early dates for wide-ranging Paleo-Indian occupation. Some sites significantly predate the migration time frame of ice-free corridors, thus suggesting that there were additional coastal migration routes available, traversed either on foot and/or in boats. Geological evidence suggests the Pacific coastal route was open for overland travel before 23,000 years ago and after 16,000 years ago.
In South America, the site of Monte Verde indicates that its population was probably territorial and resided in their river basin for most of the year. Some other South American groups, on the other hand, were highly mobile and hunted big-game animals such as mastodon and giant sloths. They used classic bifacial projectile point technology.
The primary examples are populations associated with El Jobo points (Venezuela), fish-tail or Magallanes points (various parts of the continent, but mainly the southern half), and Paijan points (Peru and Ecuador) at sites in grasslands, savanna plains, and patchy forests.
The dating for these sites ranges from c. 14,000 BP (for Taima-Taima in Venezuela) to c. 10,000 BP. The bi-pointed El Jobo projectile points were mostly distributed in north-western Venezuela; from the Gulf of Venezuela to the high mountains and valleys. The population using them were hunter-gatherers that seemed to remain within a certain circumscribed territory. El Jobo points were probably the earliest, going back to c. 14,200 – c. 12,980 BP and they were used for hunting large mammals. In contrast, the fish-tail points, dating to c. 11,000 B.P. in Patagonia, had a much wider geographical distribution, but mostly in the central and southern part of the continent.
The haplogroup most commonly associated with indigenous Amerindian genetics is Haplogroup Q-M3. Y-DNA, like (mtDNA), differs from other nuclear chromosomes in that the majority of the Y chromosome is unique and does not recombine during meiosis. This allows the historical pattern of mutations to be easily studied. The pattern indicates Indigenous Amerindians experienced two very distinctive genetic episodes; first with the initial peopling of the Americas, and secondly with European colonization of the Americas. The former is the determinant factor for the number of gene lineages and founding haplotypes present in today's Indigenous Amerindian populations.
Human settlement of the New World occurred in stages from the Bering sea coast line, with an initial layover on Beringia for the founding population. The micro-satellite diversity and distributions of the Y lineage specific to South America indicates that certain Amerindian populations have been isolated since the initial colonization of the region. The Na-Dené, Inuit and Indigenous Alaskan populations, however, exhibit haplogroup Q (Y-DNA) mutations that are distinct from other indigenous Amerindians with various mtDNA mutations. This suggests that the earliest migrants into the northern extremes of North America and Greenland derived from later migrant populations.
The Archaic period in the Americas saw a changing environment featuring a warmer more arid climate and the disappearance of the last megafauna. The majority of population groups at this time were still highly mobile hunter-gatherers, but now individual groups started to focus on resources available to them locally. Thus with the passage of time there is a pattern of increasing regional generalization like the Southwest, Arctic, Poverty, Dalton and Plano traditions. These regional adaptations would become the norm, with reliance less on hunting and gathering, and a more mixed economy of small game, fish, seasonally wild vegetables and harvested plant foods. Many groups continued to hunt big game but their hunting traditions became more varied and meat procurement methods more sophisticated. The placement of artifacts and materials within an Archaic burial site indicated social differentiation based upon status in some groups.
Archaeological evidence, in fact, recognizes that people started to leave Beringia for the New World around 40,000 years ago, but rapid expansion into North America didn't occur until about 15,000 years ago, when the ice had literally brokenpage 2 Archived 13 March 2012 at the Wayback Machine
Canada's oldest known home is a cave in Yukon occupied not 12,000 years ago as at U.S. sites, but at least 20,000 years ago
However, despite the lack of this conclusive and widespread evidence, there are suggestions of human occupation in the northern Yukon about 24,000 years ago, and hints of the presence of humans in the Old Crow Basin as far back as about 40,000 years ago.
The Ancient Beringians (AB) is a specific archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. The AB lineage diverged from the Ancestral Native American (ANA) lineage about 20,000 years ago. The ANA lineage was estimated as having been formed between 20,000 and 25,000 years ago by
a mixture of Proto-Mongoloid and used to be thought to have Ancient North Eurasian lineage, consistent with the model of the peopling of the Americas via Beringia during the Last Glacial Maximum. The Ancient Beringian lineage is extinct, and is not found as a contribution to modern indigenous lineages in Alaska. The 2018 study suggests that the AB lineage was replaced by or absorbed in a back-migration of NNA to Alaska. The modern Athabaskan populations are derived from an admixture of this NNA back-migration and a Paleo-Siberian (Early Paleo-Eskimo) lineage before about 2,500 years ago.The discovery was made from archaeogenetic analyses on the remains of two female infants discovered in 2013 at the Upward Sun River site (USR). The USR site is affiliated with the Denali Complex, a dispersed archaeological culture of the American Arctic. The genomic analysis of nuclear DNA of the older of the two infants (USR1) was done at the Centre for Geogenetics at the University of Copenhagen's Natural History Museum of Denmark. Results from the team's genetic analysis were published in January 2018 in the scientific journal Nature.
The analysis compared the infant's genomes with both ancient and contemporary genomes. The results suggested that the pre-"Ancestral Native American" lineage derived from the proto-Mongoloid lineage after 36 kya, with gene flow until about 25 kya. During 25–20 kya, this lineage was substantially mixed with the Ancient North Eurasian lineage, to form the "Ancestral Native American" lineage by 20 kya.
The "Ancient Beringian" (AB) lineage derived from ANA and persisted without significant admixture in Alaska until the time of USR1, some 8,000 years later. The lineage of other Paleo-Indians diverged form AB at ca. 20–18 kya, and further divided into "North Native American" (NNA) and "South Native American" lineages between 17.5 kya and 14.6 kya, reflecting the dispersal associated with the early peopling of the Americas.Cingulata
Cingulata, part of the superorder Xenarthra, is an order of armored New World placental mammals. Dasypodids and chlamyphorids, the armadillos, are the only surviving families in the order. Two groups of cingulates much larger than extant armadillos (maximum body mass of 45 kg (100 lb) in the case of the giant armadillo) existed until recently: pampatheriids, which reached weights of up to 200 kg (440 lb) and chlamyphorid glyptodonts, which attained masses of 2,000 kg (4,400 lb) or more.
The cingulate order originated in South America during the Paleocene epoch about 66 to 56 million years ago, and due to the continent's former isolation remained confined to it during most of the Cenozoic. However, the formation of a land bridge allowed members of all three families to migrate to southern North America during the Pliocene or early Pleistocene as part of the Great American Interchange. After surviving for tens of millions of years, all of the pampatheriids and giant glyptodonts apparently died out during the Quaternary extinction event at the beginning of the Holocene, along with much of the rest of the regional megafauna, shortly after the colonization of the Americas by Paleo-Indians.Cumberland point
A Cumberland point is a lithic projectile point, attached to a spear and used as a hunting tool. These sturdy points were intended for use as thrusting weapons and employed by various mid-Paleo-Indians (c. 11,000 BP) in the Southeastern US in the killing of large game mammals.El Fin del Mundo
El Fin del Mundo (Spanish: 'End of the World') is an ancient Pleistocene site in northwestern Sonora, Mexico. It features Clovis culture period occupation dating around 13,390 calibrated years BP. It was discovered during a 2007 survey.
This is the oldest Clovis site in North America. There's also the Aubrey site in Denton County, Texas, which produced a radiocarbon date that is almost identical.Herbert C. Kraft
Herbert Clemens Kraft (1927–2000) was an archaeologist from New Jersey, specializing in prehistory. He wrote numerous books about archaeology in New Jersey, the Lenape and the Paleo-indians of New Jersey, as well as over 170 articles in his career.History of Rocky Mountain National Park
History of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and forage for food. Ute and Arapaho people subsequently hunted and camped in the area. In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River. Settlers began arriving in the mid-1800s, displacing the Native Americans who mostly left the area voluntarily by 1860, while others were removed to reservations by 1878.Lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver. The boom ended by 1883 with miners deserting their claims. The railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U.S. Route 34 from Loveland to Estes Park—was completed in 1904. The 1920s saw a boom in building lodges and roads in the park, culminating with the construction of Trail Ridge Road to Fall River Pass between 1929 and 1932, then to Grand Lake by 1938.Prominent individuals in the effort to create a national park included Enos Mills from the Estes Park area, James Grafton Rogers from Denver, and J. Horace McFarland of Pennsylvania. The national park was established on January 26, 1915.Indigenous people of the Everglades region
The indigenous people of the Everglades region arrived in the Florida peninsula of what is now the United States approximately 14,000 to 15,000 years ago, probably following large game. The Paleo-Indians found an arid landscape that supported plants and animals adapted to prairie and xeric scrub conditions. Large animals became extinct in Florida around 11,000 years ago. Climate changes 6,500 years ago brought a wetter landscape. The Paleo-Indians slowly adapted to the new conditions. Archaeologists call the cultures that resulted from the adaptations Archaic peoples. They were better suited for environmental changes than their ancestors, and created many tools with the resources they had. Approximately 5,000 years ago, the climate shifted again to cause the regular flooding from Lake Okeechobee that gave rise to the Everglades ecosystems.
From the Archaic peoples, two major tribes emerged in the area: the Calusa and the Tequesta. The earliest written descriptions of these people come from Spanish explorers, who sought to convert and conquer them. Although they lived in complex societies, little evidence of their existence remains today. The Calusa were more powerful in number and political structure. Their territory was centered on modern-day Ft. Myers, and extended as far north as Tampa, as far east as Lake Okeechobee, and as far south as the Keys. The Tequesta lived on the southeastern coast of the Florida peninsula around what is today Biscayne Bay and the Miami River. Both societies were well adapted to live in the various ecosystems of the Everglades regions. Their people often traveled through the heart of the Everglades, though they rarely lived within it.
After more than 210 years of relations with the Spanish, both indigenous societies lost cohesiveness. Official records indicate that survivors of war and disease were transported to Havana with Spanish colonists in the late 18th century, after Great Britain took over some of the territory. Isolated groups may have been assimilated into the Seminole nation, which formed in northern Florida when a band of Creek consolidated surviving members of pre-Columbian societies in Florida into their own group to become a distinct tribe, in a process of ethnogenesis. They also were joined by free blacks and escaped slaves, who became known as Black Seminole. The Seminole were forced south and into the Everglades by the U.S. military during the Seminole Wars from 1835 to 1842. The U.S. military pursued the Seminole into the region, which resulted in some of the first recorded European-American explorations of much of the area. Federally recognized Seminole tribes continue to live in the Everglades region. Since the late 20th century, they have developed casino gambling on six reservations in the state, which generate revenues for the welfare and education of their tribes.Indigenous peoples in Ecuador
Indigenous peoples in Ecuador, also Native Ecuadorians or Native Americans, are the groups of people who were present in what became Ecuador before the Spanish colonization of the Americas. The term also includes their descendants from the time of the Spanish conquest to the present. Their history, which encompasses the last 11,000 years, reaches into the present; 25 percent of Ecuador's population is of indigenous heritage, while another 70 percent is of mixed indigenous and European heritage.Kittatinny Mountain
Kittatinny Mountain (Lenape: Kitahtëne) is a long ridge traversing across northwestern New Jersey running in a northeast-southwest axis, a continuation across the Delaware Water Gap of Pennsylvania's Blue Mountain Ridge (also known as Kittatinny Ridge). It is the first major ridge in the far northeastern extension of the Ridge and Valley province of the Appalachian Mountains, and reaches its highest elevation (the state's highest), 1,803 feet, at High Point in Montague Township. Kittatinny Mountain forms the eastern side of Wallpack Valley; the western side comprises the Wallpack Ridge (highest elevation: 928 feet (283 m) above sea level.Lithic stage
In the sequence of cultural stages first proposed for the archaeology of the Americas by Gordon Willey and Philip Phillips in 1958, the Lithic stage was the earliest period of human occupation in the Americas, as post-glacial hunters and collectors spread through the Americas.
The stage derived its name from the first appearance of Lithic flaked stone tools. The term Paleo-Indian is an alternative, generally indicating much the same period.
This stage was conceived of as embracing two major categories of stone technology: (1) unspecialized and largely unformulated core and flake industries, with percussion the dominant and perhaps only technique employed, and (2) industries exhibiting more advanced "blade" techniques of stoneworking, with specialized fluted or unfluted lanceolate points the most characteristic artifact types. Throughout South America, there are stone tool traditions of the lithic stage, such as the "fluted fishtail" that reflect localized adaptations to the diverse habitats of the continent.
The indications and timing of the end of the Lithic stage vary between regions. The use of textiles, fired pottery and start of the gradual replacement of hunter gatherer lifestyles with the use of agriculture and domesticated animals would all be factors. End dates vary, but are around 5,000 to 3,000 BC in many areas. The Archaic stage is the most widely used term for the succeeding stage, but in the periodization of pre-Columbian Peru the Cotton Pre-Ceramic may be used, as in the Norte Chico civilization cultivated cotton seems to have been very important in economic and power relations, from around 3,200 BC.
One of the leading figures is Alex Krieger who has documented hundreds of sites that have yielded crude, percussion-flaked tools. The most convincing evidence for a lithic stage is based upon data recovered from sites in South America where such crude tools have been found and dated to more than 20,000 years ago.In North America, the time encompasses the Paleo-Indian period that subsequently is divided into more specific time terms such as Early Lithic stage or Early Paleo-Indians and Middle Paleo-Indians or Middle Lithic stage. Examples include the Clovis culture and Folsom tradition groups.
The Lithic stage was followed by the Archaic stage.LoDaisKa Site
The LoDaisKa Site is a prominent archaeological site in the U.S. state of Colorado, located within a rockshelter near Morrison. The rockshelter was first inhabited by people of the Archaic through the Middle Ceramic period, generally spanning 3000 BC to 1000 AD.Mesa Verde National Park
Mesa Verde National Park is an American national park and UNESCO World Heritage Site located in Montezuma County, Colorado. The park protects some of the best-preserved Ancestral Puebloan archaeological sites in the United States.
Established by Congress and President Theodore Roosevelt in 1906, the park occupies 52,485 acres (21,240 ha) near the Four Corners region of the American Southwest. With more than 5,000 sites, including 600 cliff dwellings, it is the largest archaeological preserve in the United States. Mesa Verde (Spanish for "green table") is best known for structures such as Cliff Palace, thought to be the largest cliff dwelling in North America.
Starting c. 7500 BCE Mesa Verde was seasonally inhabited by a group of nomadic Paleo-Indians known as the Foothills Mountain Complex. The variety of projectile points found in the region indicates they were influenced by surrounding areas, including the Great Basin, the San Juan Basin, and the Rio Grande Valley. Later, Archaic people established semi-permanent rockshelters in and around the mesa. By 1000 BCE, the Basketmaker culture emerged from the local Archaic population, and by 750 CE the Ancestral Puebloans had developed from the Basketmaker culture.
The Mesa Verdeans survived using a combination of hunting, gathering, and subsistence farming of crops such as corn, beans, and squash. They built the mesa's first pueblos sometime after 650, and by the end of the 12th century, they began to construct the massive cliff dwellings for which the park is best known. By 1285, following a period of social and environmental instability driven by a series of severe and prolonged droughts, they abandoned the area and moved south to locations in Arizona and New Mexico, including Rio Chama, Pajarito Plateau, and Santa Fe.Natural Bridge State Park (Wisconsin)
Natural Bridge State Park is a 530-acre (214 ha) state park of Wisconsin, United States, featuring Wisconsin's largest natural arch. Directly beneath the arch is the Raddatz Rockshelter, a rock shelter once used by Paleo-Indians and now listed on the National Register of Historic Places. The park is located southwest of Baraboo between the unincorporated communities of Leland and Denzer, in the town of Honey Creek.Roxborough State Park Archaeological District
Roxborough State Park Archaeological District is located in Douglas County, Colorado, near the town of Waterton. Roxborough State Park, 25 miles (40 km) south of Denver, Colorado, is a Colorado State Park day park. Archaeological artifacts reflect that there were prehistoric hunter-gatherers who lived or camped, made tools from stone quarries, and farmed in the Roxborough State Park area.
Early native people inhabited the area between 5000 BC and 1000 AD and again from 1900 to 1924 AD. Roxborough State Park Archaeological District was added to the list of National Register of Historic Places in 1983.Settlement of the Americas
The first settlement of the Americas began when Paleolithic hunter-gatherers first entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum.
These populations expanded south of the Laurentide Ice Sheet and rapidly throughout both North and South America, by 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians.
The peopling of the Americas is a long-standing open question, and while advances in archaeology, Pleistocene geology, physical anthropology, and DNA analysis have shed progressively more light on the subject, significant questions remain unresolved. While there is general agreement that the Americas were first settled from Asia, the pattern of migration, its timing, and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear.The prevalent migration models outline different time frames for the Asian migration from the Bering Straits and subsequent dispersal of the founding population throughout the continent. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA.The "Clovis first theory" refers to the 1950s hypothesis that the Clovis culture represents the earliest human presence in the Americas, beginning about 13,000 years ago; evidence of pre-Clovis cultures has accumulated since 2000, pushing back the possible date of the first peopling of the Americas to about 13,200–15,500 years ago.Siberian (disambiguation)

The Stanfield-Worley Bluff Shelter, located on private property in Colbert County in northwestern Alabama, United States, is one of the most important prehistoric sites excavated in the state due to the archeological evidence deposited by the Paleo-Indians who once occupied the rock shelter. Lying in Sanderson Cove along a tributary of Cane Creek approximately seven miles (11 km) south of the Tennessee Valley, the shelter and the high bluffs of the surrounding valley provided a well-protected environment for the Native American occupants.
According to The Earliest Americans Theme Study for the Eastern United States, Stanfield-Worley Rock Shelter is considered a strong candidate for National Historic Landmark status.Stockoceros
Stockoceros is an extinct genus of the North American artiodactyl family Antilocapridae, known from Mexico and the southwestern United States. Its horns are each divided near their base into two prongs of roughly equal length.
The genus survived until about 12,000 years ago, and was present when Paleo-Indians reached North America.One of the co-discoverers of S. onusrosagris was Quentin Roosevelt II, grandson of Theodore Roosevelt; he was 14 at the time of the discovery.Tetrameryx
Tetrameryx is an extinct genus of the North American artiodactyl family Antilocapridae, known from Mexico, the western United States, and Saskatchewan. The name means "four [horned] ruminant", referring to the division of each horn near its base into two prongs; in T. shuleri, the rear prong is much longer.One member of the genus, T. shuleri, survived until about 12,000 years ago, and was present when Paleo-Indians reached North America.
