93-682: The Bahía culture (500 BCE–500 CE) was a pre-Columbian culture in Ecuador . Bahía culture originated in what is now the Manabí Province on the Pacific Coast, and spread to Bahía de Caráquez and to the Andean foothills. Their ceramic tradition is one of the first found north of the Andes . Chirije , a seaport, was a major Bahía archaeological site discovered by Emilio Estrada in

186-607: A different social structure. Until the accurate dating of Watson Brake and similar sites, the oldest mound complex was thought to be Poverty Point , also located in the Lower Mississippi Valley . Built about 1500 BCE, it is the centerpiece of a culture extending over 100 sites on both sides of the Mississippi . The Poverty Point site has earthworks in the form of six concentric half-circles, divided by radial aisles, together with some mounds. The entire complex

279-464: A land bridge from c.  30,000  – c.  11,000  YBP, followed by a Holocene sea-level rise that reopened the strait. Post-glacial rebound has continued to raise some sections of the coast. During the last glacial period , enough of the Earth's water became frozen in the great ice sheets covering North America and Europe to cause a drop in sea levels . For thousands of years

372-638: A much later date, probably no more than 2,000 years ago, moving across the ice from Siberia into Alaska. The North American climate was unstable as the ice age receded during the Lithic stage . It finally stabilized about 10,000 years ago; climatic conditions were then very similar to today's. Within this time frame, roughly about the Archaic Period , numerous archaeological cultures have been identified. The unstable climate led to widespread migration, with early Paleo-Indians soon spreading throughout

465-762: A population of over 20,000. Other chiefdoms were constructed throughout the Southeast, and its trade networks reached to the Great Lakes and the Gulf of Mexico. At its peak, between the 12th and 13th centuries, Cahokia was the most populous city in North America. (Larger cities did exist in Mesoamerica and the Andes.) Monks Mound , the major ceremonial center of Cahokia, remains the largest earthen construction of

558-480: A rich diversity of grasses and herbs. There were patches of shrub tundra with isolated refugia of larch ( Larix ) and spruce ( Picea ) forests with birch ( Betula ) and alder ( Alnus ) trees. It has been proposed that the largest and most diverse megafaunal community residing in Beringia at this time could only have been sustained in a highly diverse and productive environment. Analysis at Chukotka on

651-579: A single unified empire. The Mixtecs would eventually be conquered by the Aztecs until the Spanish conquest. The Mixtecs saw the Spanish conquest as an opportunity for liberation and established agreements with the conquistadors that allowed them to preserve their cultural traditions, though relatively few sections resisted Spanish rule. The Totonac civilization was concentrated in the present-day states of Veracruz and Puebla . The Totonacs were responsible for

744-463: A variety of tools, including distinctive projectile points and knives, as well as less distinctive butchering and hide-scraping implements. The vastness of the North American continent, and the variety of its climates, ecology , vegetation , fauna , and landforms, led ancient peoples to coalesce into many distinct linguistic and cultural groups. This is reflected in the oral histories of

837-631: Is Y-chromosome haplogroup Q1a3a . Researchers have found genetic evidence that the Q1a3a haplogroup has been in South America since at least 18,000 BCE. Y-chromosome 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 has the effect that the historical pattern of mutations can easily be studied. The pattern indicates Indigenous peoples of

930-411: Is nearly a mile across. Mound building was continued by succeeding cultures, who built numerous sites in the middle Mississippi and Ohio River valleys as well, adding effigy mounds , conical and ridge mounds, and other shapes. The Woodland period of North American pre-Columbian cultures lasted from roughly 1000 BCE to 1000 CE. The term was coined in the 1930s and refers to prehistoric sites between

1023-593: Is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near

1116-646: The Anadyr River ), and Arctodus simus , American badger , American kiang -like equids, Bootherium and Camelops in North America, with the existence of Homotherium being disputed in Late Pleistocene Siberia. The lack of mastodon and Megalonyx has been attributed to their inhabitation of Alaska and the Yukon being limited to interglacials. However, ground sloth eDNA has potentially been recovered from Siberia. The peopling of

1209-670: The Archaic period and the Mississippian cultures . The Adena culture and the ensuing Hopewell tradition during this period built monumental earthwork architecture and established continent-spanning trade and exchange networks. This period is considered a developmental stage without any massive changes in a short period but instead has a continuous development in stone and bone tools, leatherworking, textile manufacture, tool production, cultivation, and shelter construction. Some Woodland people continued to use spears and atlatls until

1302-1306: The Chukchi Sea , the Bering Sea , the Bering Strait , the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States and the Yukon in Canada . The area includes land lying on the North American Plate and Siberian land east of the Chersky Range . At various times, it formed a land bridge referred to as the Bering land bridge , that was up to 1,000 km (620 mi) wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling about 1.6 million km (620,000 sq mi), allowing biological dispersal to occur between Asia and North America. Today,

1395-702: The Cliff Palace of Mesa Verde National Park in Colorado and the Great Houses in Chaco Canyon , New Mexico . The Puebloans also constructed a road system that stretched from Chaco Canyon to Kutz Canyon in the San Juan Basin . The Ancestral Puebloans are also known as "Anasazi", though the term is controversial, as the present-day Pueblo peoples consider the term to be derogatory, due to

1488-611: The Last Glacial Maximum , when ice sheets began advancing from 33,000   YBP and reached their maximum limits 26,500   YBP. Deglaciation commenced in the Northern Hemisphere approximately 19,000   YBP and in Antarctica approximately 14,500 years   YBP, which is consistent with evidence that glacial meltwater was the primary source for an abrupt rise in sea level 14,500   YBP and

1581-697: The Maya script . Other accounts also suggest that the Huastecs migrated as a result of the Classic Maya collapse around the year 900 CE. The Zapotecs were a civilization that thrived in the Oaxaca Valley from the late 6th century BCE until their downfall at the hands of the Spanish conquistadors. The city of Monte Albán was an important religious center for the Zapotecs and served as the capital of

1674-664: The Olmec , Teotihuacan , Mayas , Zapotecs , Mixtecs , Huastecs , Purepecha , Toltecs , and Mexica / Aztecs . The Mexica civilization is also known as the Aztec Triple Alliance since they were three smaller kingdoms loosely united together. These Indigenous civilizations are credited with many inventions: building pyramid temples, mathematics , astronomy , medicine, writing, highly accurate calendars , fine arts , intensive agriculture, engineering , an abacus calculator, and complex theology . They also invented

1767-726: The Spanish conquest of El Salvador , Cuzcatlan was forced to surrender to conquistador Pedro de Alvarado in 1528. Beringia Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia ; on the east by the Mackenzie River in Canada ; on the north by 72° north latitude in the Chukchi Sea ; and on the south by the tip of the Kamchatka Peninsula . It includes

1860-463: The Tlingit , Haida , Chumash , Mandan , Hidatsa , and others, and some established large settlements, even cities, such as Cahokia , in what is now Illinois . Mesoamerica is the region extending from central Mexico south to the northwestern border of Costa Rica that gave rise to a group of stratified, culturally related agrarian civilizations spanning an approximately 3,000-year period before

1953-506: The founding population . The microsatellite diversity and distributions of the Y lineage specific to South America indicate that certain Amerindian populations have been isolated since the initial colonization of the region. The Na-Dené , Inuit , and Indigenous Alaskan populations exhibit haplogroup Q-M242 (Y-DNA) mutations, however, and are distinct from other Indigenous peoples with various mtDNA mutations. This suggests that

Merchants traded finished goods and Spondylus princeps or red spiny oyster shells south to Chile and north as far as Mexico in exchange for precious materials such as copper and gold. This Ecuador -related article is a stub . You can help Misplaced Pages by expanding it . Pre-Columbian During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major earthworks , and complex societal hierarchies. Some of these civilizations had declined by

2139-790: The Americas began when Paleolithic hunter-gatherers ( Paleo-Indians ) 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 (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly southward, occupying both North and South America by 12,000 to 14,000 years ago. The earliest populations in

2232-455: The Americas experienced two very distinctive genetic episodes: first with the initial peopling of the Americas and second 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 populations . Human settlement of the Americas occurred in stages from the Bering Sea coastline , with an initial 20,000-year layover on Beringia for

2325-634: The Americas sometime after 16,500 years Before Present (YBP). This would have occurred as the American glaciers blocking the way southward melted, but before the bridge was covered by the sea about 11,000 YBP. The term Beringia was coined by the Swedish botanist Eric Hultén in 1937, from the Danish-born Russian explorer Vitus Bering . During the ice ages, Beringia, like most of Siberia and all of North and Northeast China ,

2418-491: The Americas, before roughly 10,000 years ago, are known as Paleo-Indians . Indigenous peoples of the Americas have been linked to Siberian populations by proposed linguistic factors , the distribution of blood types , and in genetic composition as reflected by molecular data, such as DNA . Around 3,000 years ago, the progenitors of the Yupik peoples settled along both sides of the straits. The governments of Russia and

2511-604: The Americas, diversifying into many hundreds of culturally distinct tribes. The Paleo-Indians were hunter-gatherers , likely characterized by small, mobile bands consisting of approximately 20 to 50 members of an extended family. These groups moved from place to place as preferred resources were depleted and new supplies were sought. During much of the Paleo-Indian period, bands are thought to have subsisted primarily through hunting now-extinct giant land animals such as mastodon and ancient bison . Paleo-Indian groups carried

2604-477: The Europeans arrived, Indigenous peoples of North America had a wide range of lifeways from sedentary, agrarian societies to semi-nomadic hunter-gatherer societies. Many formed new tribes or confederations in response to European colonization. These are often classified by cultural regions , loosely based on geography. These can include the following: Numerous pre-Columbian societies were sedentary, such as

2697-668: The Hohokam, they constructed kivas and great houses as well as ballcourts . Several of the Sinagua ruins include Montezuma Castle , Wupatki , and Tuzigoot . The Salado resided in the Tonto Basin in southeastern Arizona from 1150 CE to the 15th century. Archaeological evidence suggests that they traded with far-away cultures, as evidenced by the presence of seashells from the Gulf of California and macaw feathers from Mexico. Most of

2790-494: The Last Glacial Maximum. This was followed by a single population of modern wolves expanding out of their Beringia refuge to repopulate the wolf's former range, replacing the remaining Late Pleistocene wolf populations across Eurasia and North America. The extinct pine species Pinus matthewsii has been described from Pliocene sediments in the Yukon areas of the refugium. The existence of fauna endemic to

2883-734: The Maya city of Chichen Itza . The Toltecs established vast trading relations with other Mesoamerican civilizations in Central America and the Puebloans in present-day New Mexico . During the Post-Classic era, the Toltecs suffered a subsequent collapse in the early 12th century, due to famine and civil war. The Toltec civilization was so influential to the point where many groups such as the Aztecs claimed to be descended from. With

2976-454: The Maya civilization cannot be overstated: it transformed political power, artistic depictions, and the nature of economics. Within the city of Teotihuacan was a diverse and cosmopolitan population. Most of the regional ethnicities of Mexico were represented in the city, such as Zapotecs from the Oaxaca region. They lived in apartment communities where they worked their trades and contributed to

3069-841: The Mississippian groups had vanished, and vast swaths of their territory were virtually uninhabited. The Ancestral Puebloans thrived in what is now the Four Corners region in the United States. It is commonly suggested that the culture of the Ancestral Puebloans emerged during the Early Basketmaker II Era during the 12th century BCE. The Ancestral Puebloans were a complex Oasisamerican society that constructed kivas , multi-story houses, and apartment blocks made from stone and adobe, such as

3162-483: The Olmec resulted in a power vacuum in Mexico. Emerging from that vacuum was Teotihuacan, first settled in 300 BCE. By 150 CE, Teotihuacan had risen to become the first true metropolis of what is now called North America. Teotihuacan established a new economic and political order never before seen in Mexico. Its influence stretched across Mexico into Central America, founding new dynasties in the Maya cities of Tikal , Copan , and Kaminaljuyú . Teotihuacan's influence over

3255-744: The Olmecs, Teotihuacan, the Toltecs, the Mexica, and the Mayas. These civilizations (except for the politically fragmented Maya) extended their reach across Mesoamerica—and beyond—like no others. They consolidated power and distributed influence in matters of trade, art, politics, technology, and theology. Other regional power players made economic and political alliances with these civilizations over 4,000 years. Many made war with them, but almost all peoples found themselves within one of their spheres of influence. Regional communications in ancient Mesoamerica have been

3348-523: The Siberian edge of the land bridge indicated that from c.  57,000  – c.  15,000  YBP (MIS 3 to MIS 2) the environment was wetter and colder than the steppe–tundra to the east and west, with warming in parts of Beringia from c.  15,000  YBP. These changes provided the most likely explanation for mammal migrations after c.  15,000  YBP, as the warming provided increased forage for browsers and mixed feeders. At

3441-459: The Spanish colonists. The Wichita people were a loose confederation that consisted of sedentary agriculturalists and hunter-gatherers who resided in the eastern Great Plains . They lived in permanent settlements and even established a city called Etzanoa , which had a population of 20,000 people. The city was eventually abandoned around the 18th century after it was encountered by Spanish conquistadors Jusepe Gutierrez and Juan de Oñate . When

3534-619: The Tlaxcalans for preserving their culture and for their assistance in defeating the Aztecs. The Tlaxcalans would once again assist to the Spaniards during the Mixtón War and the conquest of Guatemala . Cuzcatlan was a Pipil confederacy of kingdoms and city-states located in present-day El Salvador . According to legend, Cuzcatlan was established by Toltec migrants during the Classic Maya collapse in approximately 1200 CE. During

3627-818: The United States announced a plan to formally establish "a transboundary area of shared Beringian heritage". Among other things this agreement would establish close ties between the Bering Land Bridge National Preserve and the Cape Krusenstern National Monument in the United States and Beringia National Park in Russia. Biogeographical evidence demonstrates previous connections between North America and Asia. Similar dinosaur fossils occur both in Asia and in North America . The dinosaur Saurolophus

3720-499: The Yukon where it was blocked by the Wisconsin glaciation . Therefore, the flora and fauna of Beringia were more related to those of Eurasia rather than North America. Beringia received more moisture and intermittent maritime cloud cover from the north Pacific Ocean than the rest of the Mammoth steppe, including the dry environments on either side of it. This moisture supported a shrub-tundra habitat that provided an ecological refugium for plants and animals. In East Beringia 35,000 YBP,

3813-466: The Yukon. In the driest and coldest periods of the Late Pleistocene, and possibly during the entire Pleistocene, moisture occurred along a north–south gradient with the south receiving the most cloud cover and moisture due to the air-flow from the North Pacific. In the Late Pleistocene, Beringia was a mosaic of biological communities. Commencing from c.  57,000  YBP ( MIS 3), steppe–tundra vegetation dominated large parts of Beringia with

3906-539: The beginning of the Holocene , some mesic habitat -adapted species left the refugium and spread westward into what had become tundra-vegetated northern Asia and eastward into northern North America. The latest emergence of the land bridge was c.  70,000 years ago. However, from c.  24,000  – c.  13,000  YBP the Laurentide Ice Sheet fused with the Cordilleran Ice Sheet , which blocked gene flow between Beringia (and Eurasia) and continental North America. The Yukon corridor opened between

3999-412: The bridge was finally inundated around 11,000 YBP. The fossil evidence from many continents points to the extinction of large animals, termed Pleistocene megafauna , near the end of the last glaciation. During the Ice Age a vast, cold and dry Mammoth steppe stretched from the arctic islands southwards to China, and from Spain eastwards across Eurasia and over the Bering land bridge into Alaska and

4092-443: The calendar, were bequest from the former inhabitants of Tula, the Toltecs. The Mexica-Aztecs were the rulers of much of central Mexico by about 1400 (while Yaquis , Coras, and Apaches commanded sizable regions of northern desert), having subjugated most of the other regional states by the 1470s. At their peak, the Valley of Mexico where the Aztec Empire presided, saw a population growth that included nearly one million people during

4185-457: The city's economic and cultural prowess. Teotihuacan's economic pull impacted areas in northern Mexico as well. It was a city whose monumental architecture reflected a monumental new era in Mexican civilization, declining in political power about 650 CE—but lasting in cultural influence for the better part of a millennium, to around 950 CE. Contemporary to Teotihuacan's greatness was that of the Maya civilization. The period between 250 CE and 650 CE

4278-406: The civilizations in its area, the Tarascan Empire was the most prominent in metallurgy, harnessing copper, silver, and gold to create items such as tools, decorations, and even weapons and armor. Bronze was also used. The great victories over the Aztecs by the Tarascans cannot be understated. Nearly every war they fought in resulted in a Tarascan victory. Because the Tarascan Empire had little links to

4371-429: The cliff dwellings constructed by the Salado are primarily located in Tonto National Monument . The Iroquois League of Nations or "People of the Long House" was a politically advanced, democratic society, which is thought by some historians to have influenced the United States Constitution , with the Senate passing a resolution to this effect in 1988. Other historians have contested this interpretation and believe

4464-421: The climate was warmer and wetter. The environmental conditions were not homogenous in Beringia. Recent stable isotope studies of woolly mammoth bone collagen demonstrate that western Beringia ( Siberia ) was colder and drier than eastern Beringia ( Alaska and Yukon ), which was more ecologically diverse. Grey wolves suffered a species-wide population bottleneck (reduction) approximately 25,000 YBP during

4557-404: The coast in southeast Veracruz . The Olmec influence extended across Mexico, into Central America , and along the Gulf of Mexico . They transformed many peoples' thinking toward a new way of government, pyramid temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico. The decline of

4650-439: The colonization of the Americas dates from between 40,000 and 13,000 years ago. The chronology of migration models is currently divided into two general approaches. The first is the short chronology theory with the first movement beyond Alaska into the Americas occurring no earlier than 14,000–17,000 years ago, followed by successive waves of immigrants. The second belief is the long chronology theory , which proposes that

4743-432: The de Soto expedition wandered the American Southeast for four years, becoming more bedraggled, losing more men and equipment, and eventually arriving in Mexico as a fraction of its original size. The local people fared much worse though, as the fatalities of diseases introduced by the expedition devastated the populations and produced much social disruption. By the time Europeans returned a hundred years later, nearly all of

4836-463: The decline of the Toltec civilization came political fragmentation in the Valley of Mexico . Into this new political game of contenders to the Toltec throne stepped outsiders: the Mexica . They were also a desert people, one of seven groups who formerly called themselves "Azteca", in memory of Aztlán , but they changed their name after years of migrating. Since they were not from the Valley of Mexico , they were initially seen as crude and unrefined in

4929-423: The destruction, a few original documents have survived, and others were transcribed or translated into Spanish, providing modern historians with valuable insights into ancient cultures and knowledge. Before the development of archaeology in the 19th century, historians of the pre-Columbian period mainly interpreted the records of the European conquerors and the accounts of early European travelers and antiquaries. It

5022-426: The dry beds of the English Channel and North Sea , and the dry bed of the South China Sea linked Sumatra , Java , and Borneo to Indochina . The last glacial period , commonly referred to as the "Ice Age", spanned 125,000 –14,500   YBP and was the most recent glacial period within the current ice age , which occurred during the last years of the Pleistocene era. The Ice Age reached its peak during

5115-471: The earliest migrants into the northern extremes of North America and Greenland derived from later populations. Asian nomadic Paleo-Indians are thought to have entered the Americas via the Bering Land Bridge (Beringia), now the Bering Strait , and possibly along the coast. Genetic evidence found in Indigenous peoples ' maternally inherited mitochondrial DNA (mtDNA) supports the theory of multiple genetic populations migrating from Asia. After crossing

5208-430: The empire from 700 BCE to 700 CE. The Zapotecs resisted the expansion of the Aztecs until they were subjugated in 1502 under Aztec emperor Ahuitzotl . After the Spanish conquest of the Aztec Empire , the Zapotecs resisted Spanish rule until King Cosijopii I surrendered in 1563. Like the Zapotecs, the Mixtecs thrived in the Oaxaca Valley. The Mixtecs consisted of separate independent kingdoms and city-states, rather than

5301-409: The end of the period when they were replaced by bows and arrows . The Mississippian culture was spread across the Southeast and Midwest of what is today the United States, from the Atlantic coast to the edge of the plains, from the Gulf of Mexico to the Upper Midwest, although most intensively in the area along the Mississippi River and Ohio River . One of the distinguishing features of this culture

5394-408: The establishment of cities, such as El Tajín as important commercial trading centers. The Totonacs would later assist in the Spanish conquest of the Aztec Empire as an opportunity to liberate themselves from Aztec military imperialism. The Toltec civilization was established in the 8th century CE. The Toltec Empire expanded its political borders to as far south as the Yucatán peninsula , including

5487-403: The first Cazonci, Tariacuri, united these communities and built them into one of the most advanced civilizations in Mesoamerica. Their capital at Tzintzuntzan was just one of the many cities—there were ninety more under its control. The Tarascan Empire was among the largest in Central America, so it is no surprise that they routinely came into conflict with the neighboring Aztec Empire . Out of all

5580-411: The first group of people entered the hemisphere at a much earlier date, possibly 50,000–40,000 years ago or earlier. Artifacts have been found in both North and South America which have been dated to 14,000 years ago, and accordingly humans have been proposed to have reached Cape Horn at the southern tip of South America by this time. In that case, the Inuit would have arrived separately and at

5673-400: The former Toltec Empire , they were also quite independent in culture from their neighbors. The Aztecs, Tlaxcaltec , Olmec, Mixtec, Maya, and others were very similar to each other, however. This is because they were all directly preceded by the Toltecs, and they therefore shared almost identical cultures. The Tarascans, however, possessed a unique religion, as well as other things.

5766-531: The globe. Today, the average water depth of the Bering Strait is 40–50 m (130–160 ft); therefore the land bridge opened when the sea level dropped more than 50 m (160 ft) below the current level. A reconstruction of the sea-level history of the region indicated that a seaway existed from c.  135,000  – c.  70,000  YBP, a land bridge from c.  70,000  – c.  60,000  YBP, an intermittent connection from c.  60,000  – c.  30,000  YBP,

5859-517: The ice mass balance, leading to global sea-level fluctuations were viewed as the cause of the Bering land bridge. In 1937, Eric Hultén proposed that around the Aleutians and the Bering Strait region were tundra plants that had originally dispersed from a now-submerged plain between Alaska and Chukotka, which he named Beringia after Vitus Bering who had sailed into the strait in 1728. The American arctic geologist David Hopkins redefined Beringia to include portions of Alaska and Northeast Asia. Beringia

5952-543: The impact was minimal or did not exist, pointing to numerous differences between the two systems and the ample precedents for the constitution in European political thought. The Calusa were a complex paramountcy/kingdom that resided in southern Florida . Instead of agriculture, the Calusa economy relied on abundant fishing. According to Spanish sources, the "king's house" at Mound Key was large enough to house 2,000 people. The Calusa ultimately collapsed into extinction at around 1750 after succumbing to diseases introduced by

6045-484: The indigenous peoples, described by a wide range of traditional creation stories which often say that a given people have been living in a certain territory since the creation of the world. Throughout thousands of years, paleo-Indian people domesticated, bred, and cultivated many plant species, including crops that now constitute 50–60% of worldwide agriculture. In general, Arctic, Subarctic, and coastal peoples continued to live as hunters and gatherers, while agriculture

6138-687: The influence that astronomical activities had upon Mesoamerican people before the arrival of Europeans. Many of the later Mesoamerican civilizations carefully built their cities and ceremonial centers according to specific astronomical events. The biggest Mesoamerican cities, such as Teotihuacan , Tenochtitlan , and Cholula , were among the largest in the world. These cities grew as centers of commerce, ideas, ceremonies, and theology, and they radiated influence outwards onto neighboring cultures in central Mexico. While many city-states, kingdoms, and empires competed with one another for power and prestige, Mesoamerica can be said to have had five major civilizations:

6231-509: The land bridge, they moved southward along the Pacific coast and through an interior ice-free corridor. Throughout millennia, Paleo-Indians spread throughout the rest of North and South America. Exactly when the first people migrated into the Americas is the subject of much debate. One of the earliest identifiable cultures was the Clovis culture , with sites dating from some 13,000 years ago. However, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate

6324-472: The late Aztec period (1350–1519). Their capital, Tenochtitlan , is the site of modern-day Mexico City . At its peak, it was one of the largest cities in the world with population estimates of 200,000–300,000. The market established there was the largest ever seen by the conquistadores on arrival. Initially, the lands that would someday comprise the lands of the powerful Tarascan Empire were inhabited by several independent communities. Around 1300, however,

6417-607: The late twentieth century, archeologists have studied, analyzed, and dated these sites, realizing that the earliest complexes were built by hunter-gatherer societies, whose people occupied the sites on a seasonal basis. Watson Brake , a large complex of eleven platform mounds, was constructed beginning in 3400 BCE and added to over 500 years. This has changed earlier assumptions that complex construction arose only after societies had adopted agriculture, and become sedentary, with stratified hierarchy and usually ceramics. These ancient people had organized to build complex mound projects under

6510-421: The northern arctic areas experienced temperatures 1.5 °C (2.7 °F) degrees warmer than today but the southern sub-Arctic regions were 2 °C (4 °F) degrees cooler. During the LGM 22,000 YBP the average summer temperature was 3–5 °C (5–9 °F) degrees cooler than today, with variations of 2.9 °C (5.2 °F) degrees cooler on the Seward Peninsula to 7.5 °C (13.5 °F) cooler in

6603-409: The only land that is visible from the central part of the Bering land bridge are the Diomede Islands , the Pribilof Islands of St. Paul and St. George, St. Lawrence Island , St. Matthew Island , and King Island . It is believed that a small human population of at most a few thousand arrived in Beringia from eastern Siberia during the Last Glacial Maximum before expanding into the settlement of

The Huastecs were a Maya ethnic group that migrated northwards to the Gulf Coast of Mexico. The Huastecs are considered to be distinct from the Maya civilization, as they separated from the main Maya branch at around 2000 BCE and did not possess

Fossil evidence also indicates an exchange of primates and plants between North America and Asia around 55.8 million years ago. 20 million years ago, evidence in North America shows the last natural interchange of mammalian species. Some, like the ancient saber-toothed cats , have a recurring geographical range: Europe, Africa, Asia, and North America. The pattern of bidirectional flow of biota has been asymmetric, with more plants, animals, and fungi generally migrating from Asia to North America than vice versa throughout

6882-657: The people abandoned their settlements, likely due to drought. The Mogollon resided in the present-day states of Arizona , New Mexico, and Texas as well as Sonora and Chihuahua . Like most other cultures in Oasisamerica, the Mogollon constructed sophisticated kivas and cliff dwellings. In the village of Paquimé , the Mogollon are revealed to have housed pens for scarlet macaws , which were introduced from Mesoamerica through trade. The Sinagua were hunter-gatherers and agriculturalists who lived in central Arizona. Like

6975-416: The prehistoric Americas . The culture reached its peak in about 1200–1400 CE, and in most places, it seems to have been in decline before the arrival of Europeans. Many Mississippian peoples were encountered by the expedition of Hernando de Soto in the 1540s, mostly with disastrous results for both sides. Unlike the Spanish expeditions in Mesoamerica, which conquered vast empires with relatively few men,

7068-468: The receding ice sheets c.  13,000  YBP, and this once again allowed gene flow between Eurasia and continental North America until the land bridge was finally closed by rising sea levels c.  10,000  YBP. During the Holocene, many mesic-adapted species left the refugium and spread eastward and westward, while at the same time the forest-adapted species spread with the forests up from

7161-495: The respective Siberian and North American portions of Beringia has led to the 'Beringian Gap' hypothesis, wherein an unconfirmed geographic factor blocked migration across the land bridge when it emerged. Beringia did not block the movement of most dry steppe-adapted large species such as saiga antelope, woolly mammoth, and caballid horses. Notable restricted fauna include the woolly rhino in Siberia (which went no further east than

7254-479: The sea floors of many interglacial shallow seas were exposed, including those of the Bering Strait , the Chukchi Sea to the north, and the Bering Sea to the south. Other land bridges around the world have emerged and disappeared in the same way. Around 14,000 years ago, mainland Australia was linked to both New Guinea and Tasmania , the British Isles became an extension of continental Europe via

7347-607: The south. The arid-adapted species were reduced to minor habitats or became extinct. Beringia constantly transformed its ecosystem as the changing climate affected the environment, determining which plants and animals were able to survive. The land mass could be a barrier as well as a bridge: during colder periods, glaciers advanced and precipitation levels dropped. During warmer intervals, clouds, rain and snow altered soils and drainage patterns. Fossil remains show that spruce , birch and poplar once grew beyond their northernmost range today, indicating that there were periods when

7440-619: The subject of considerable research. There is evidence of trade routes starting as far north as the Mexico Central Plateau , and going down to the Pacific coast. These trade routes and cultural contacts then went on as far as Central America . These networks operated with various interruptions from pre-Olmec times and up to the Late Classical Period (600–900 CE). The earliest known civilization in Mesoamerica

7533-599: The time of the establishment of the first permanent European colonies, around the late 16th to early 17th centuries, and are known primarily through archaeological research of the Americas and oral histories. Other civilizations, contemporaneous with the colonial period, were documented in European accounts of the time. For instance, the Maya civilization maintained written records, which were often destroyed by Christian Europeans such as Diego de Landa , who viewed them as pagan but sought to preserve native histories. Despite

7626-555: The visits to the Caribbean by Christopher Columbus. Mesoamerican is the adjective generally used to refer to that group of pre-Columbian cultures. This refers to an environmental area occupied by an assortment of ancient cultures that shared religious beliefs, art, architecture, and technology in the Americas for more than three thousand years. Between 2000 and 300 BCE, complex cultures began to form in Mesoamerica. Some matured into advanced pre-Columbian Mesoamerican civilizations such as

7719-500: The ways of the Nahua civilization. Through political maneuvers and ferocious martial skills, they managed to rule Mexico as the head of the 'Triple Alliance' which included two other Aztec cities, Tetxcoco and Tlacopan . Latecomers to Mexico's central plateau , the Mexica thought of themselves, nevertheless, as heirs of the civilizations that had preceded them. For them, arts, sculpture, architecture, engraving, feather-mosaic work, and

7812-420: The wheel, but it was used solely as a toy. In addition, they used native copper , silver , and gold for metalworking. Archaic inscriptions on rocks and rock walls all over northern Mexico (especially in the state of Nuevo León ) demonstrate an early propensity for counting. Their number system was base 20 and included zero . These early count markings were associated with astronomical events and underscore

7905-722: The word tracing its origins to a Navajo word meaning "ancestor enemies". The Hohokam thrived in the Sonoran desert in what is now the U.S. state of Arizona and the Mexican state of Sonora . The Hohokam were responsible for the construction of a series of irrigation canals that led to the successful establishment of Phoenix, Arizona via the Salt River Project . The Hohokam also established complex settlements such as Snaketown , which served as an important commercial trading center. After 1375 CE, Hohokam society collapsed and

7998-493: Was a Nahua republic and confederation in central Mexico. The Tlaxcalans fiercely resisted Aztec expansion during the Flower Wars ever since the Aztecs expelled them from Lake Texcoco . The Tlaxcalans would later ally with the Spanish conquistadors under Hernán Cortés as an opportunity to liberate them from the Aztecs and managed to successfully conquer the Aztecs with the help of the conquistadors. The Spaniards would reward

8091-416: Was a time of intense flourishing of Maya civilized accomplishments. While the many Maya city-states never achieved political unity on the order of the central Mexican civilizations, they exerted tremendous intellectual influence upon Mexico and Central America. The Maya built some of the most elaborate cities on the continent and made innovations in mathematics, astronomy, and calendrics. The Maya also developed

8184-583: Was adopted in more temperate and sheltered regions, permitting a dramatic rise in population. After the migration or migrations, it was several thousand years before the first complex societies arose, the earliest emerging about seven to eight thousand years ago. As early as 5500 BCE, people in the Lower Mississippi Valley at Monte Sano and other sites in present-day Louisiana , Mississippi , and Florida were building complex earthwork mounds , probably for religious purposes. Beginning in

8277-512: Was found in both Mongolia and western North America. Relatives of Troodon , Triceratops , and Tyrannosaurus rex all came from Asia. The earliest Canis lupus specimen was a fossil tooth discovered at Old Crow, Yukon , Canada. The specimen was found in sediment dated 1 million YBP, however the geological attribution of this sediment is questioned. Slightly younger specimens were discovered at Cripple Creek Sump, Fairbanks , Alaska, in strata dated 810,000 YBP. Both discoveries point to

8370-646: Was later regarded as extending from the Verkhoyansk Mountains in the west to the Mackenzie River in the east. The distribution of plants in the genera Erythranthe and Pinus are good examples of this, as very similar genera members are found in Asia and the Americas. During the Pleistocene epoch, global cooling led periodically to the expansion of glaciers and the lowering of sea levels. This created land connections in various regions around

8463-461: Was not glaciated because snowfall was very light . The remains of Late Pleistocene mammals that had been discovered on the Aleutians and islands in the Bering Sea at the close of the nineteenth century indicated that a past land connection might lie beneath the shallow waters between Alaska and Chukotka . The underlying mechanism was first thought to be tectonics, but by 1930 changes in

8556-569: Was not until the nineteenth century that the work of people such as John Lloyd Stephens , Eduard Seler , and Alfred Maudslay , and institutions such as the Peabody Museum of Archaeology and Ethnology of Harvard University , led to the reconsideration and criticism of the early European sources. Now, the scholarly study of pre-Columbian cultures is most often based on scientific and multidisciplinary methodologies. The haplogroup most commonly associated with Indigenous Amerindian genetics

8649-538: Was the construction of complexes of large earthen mounds and grand plazas, continuing the mound-building traditions of earlier cultures. They grew maize and other crops intensively, participated in an extensive trade network, and had a complex stratified society. The Mississippians first appeared around 1000 CE, following and developing out of the less agriculturally intensive and less centralized Woodland period. The largest urban site of these people, Cahokia —located near modern East St. Louis, Illinois —may have reached
