Clovis points exhibiting characteristic channels, or flutes, that extend from mid-blade to the base of the implement.Among the more popular misconceptions were those holding that the first residents of the continent had been members of the Ten Lost Tribes of Israel or refugees from the lost island of Atlantis, that their descendents had developed the so-called Mound Builder culture, and that Native Americans had later overrun and destroyed the Mound Builder civilization.These erroneous and overtly racist beliefs were often used to rationalize the destruction or displacement of indigenous Americans.
Such beliefs were not dispelled until the 1890s, when Cyrus Thomas, a pioneering archaeologist employed by the Smithsonian Institution, demonstrated conclusively that the great effigy mounds, burial mounds, and temple mounds of the Northeast and Southeast culture areas had been built by Native Americans. Monks Mound, Cahokia State Historic Site, Illinois Monks Mound, the largest man-made earthen structure in North America, is part of Cahokia Mounds State Historic Site, near Cahokia and Collinsville, Illinois, U.S. Monks Mound covers some 15 acres (6 hectares) and is approximately 100 feet (30 metres) high; it dwarfs the automobile visible on the road in this photograph. During the last ice age, a land bridge (a misnomer for a very broad swath of land) connected northeastern Asia to northwestern North America. The land route is known as Beringia because it formed along the present-day Bering Strait. Paleo-Indian archaeological sites Paleo-Indian archaeological sites suggesting coastal and inland migration routes. Beringia began to emerge some 36,00040,000 years ago, as the ice age began. At that time glaciers began to absorb increasing amounts of water, causing global sea levels to fall by as much as 400 feet (120 metres). A complete connection between Asia and North America existed from about 28,000 to 10,000 bce, and, at its greatest extent, Beringia may have spanned some 1,000 miles (1,600 km) from north to south. The people who moved into Beringia from Asia relied on hunting and gathering for subsistence and traveled in bands: small, mobile, kin-based groups of people who lived and foraged together. Three factors suggested that Beringia was inhabited for some time before people moved into North America itself: the long period during which the land route existed, the generally slow advance of hunter-gatherers into new territory, and the presence of unsurpassable glaciers at Beringias eastern extreme until perhaps 13,000 bce. When calculated from the point where sea levels began to expose the land route, Beringia may have been inhabited for as long as 20,000 years. As the eastern glaciers began to recede, some Beringians probably followed the coast south, perhaps combining walking with boat travel; people had used boats to settle Australia as early as 50,00060,000 bce, which suggests that such technology was by this time well-known. Prehistoric Tribes For Pc Free Routes ThroughOther Beringians probably traveled via ice-free routes through the interior of North America; geological studies indicate that such passages probably existed in the Mackenzie Basin and along the Yukon, Liard, and Peace river systems. However, recent evidence has revealed that the ice-free routes were not viable until 12,600 years before the present. Yet numerous sites, including Gault (Texas), Monte Verde (Chile), Paisley Caves (Oregon), Meadowcroft Rockshelter (Pennsylvania), Cactus Hill (Virginia), Miles Point (Maryland), and others, have established that people were in the Americas 5,0008,000 years before the ice-free routes were available, establishing that initial migration had to have been along one or both coasts. In studies of North American prehistory, these very early cultures are generally known as Paleo-Indians. By about 6000 bce some groups had begun to experiment with food production as well as foraging; they are known as Archaic cultures. Archaic peoples often returned to the same location on a seasonal basis, and as a result began to build small settlements. Archaic subsistence techniques were very efficient, and in a number of culture areas people sustained an essentially Archaic way of life until after European colonization. ![]() These groups include the early farmers of the Southwest, known as the Ancestral Pueblo culture, Mogollon culture, and Hohokam culture; those east of the Mississippi valley, known as Woodland cultures and later as Mississippian cultures; and those who settled along the rivers of the Plains, known as members of the Plains Woodland and the Plains Village cultures. Paleo-Indian cultures Asia and North America remained connected until about 12,000 years ago. Although most of the routes used by the Paleo-Indians are difficult to investigate because they are now under water or deeply buried or have been destroyed by erosion and other geological processes, research has divulged a variety of information about their lives and cultures.
