Paleo-Indian Migration North and South
America
Clovis Folsom Plainview Archaic Artifacts and skeletal remains of Cro-Magnon (modern man) did not appear in Africa until about 50000 B.C.. By 40000 B.C. there was abundant evidence of modern man in southwestern Europe as well as across Eurasia. Within a couple of thousand years, the Cro-Magnons obliterated the Neanderthals of Eurasia that had been there for 80,000 plus years. At the end of the last Ice Age (late Pleistocene period), lowering sea levels created a land mass between Siberia and Alaska. The 580,000 square mile land mass was called Beringia. The Beringia land mass was an area about twice the size of Texas. This fifty-five mile long land bridge connected Siberia and North America for approximately 3,500 years. At the University of Colorado's Institute of Arctic and Alpine Research, radiocarbon dating by Dr. Scott Elias has shown lowering sea levels created this land bridge about 14000 B.C., and by 10500 B.C., rising sea water had submerged the Beringia land mass beneath the Bering Strait. Based on plant life from sea-core samples, Dr. Ellis believes the area was covered with tundra plants and shrubs rather than an arid grassland. His findings indicate Beringia was unsuitable for extended habitation by large grazing animals.
Small isolated bands of Paleo-Indian hunter-gatherers followed herds of large of migrating herbivores across Beringia into Alaska. About 13500 B.C., an ice free corridor developed down the Yukon Valley to the grasslands below Edmonton, Canada. This allowed animals and hunter-gatherers to migrate south. According to Jared Diamond, nothing moved from Alaska across the glacial ice sheets to the Great Plains south of Edmonton, Canada until the Yukon Valley was free of ice.
Scientific evidence links most of the first inhabitants of the Americas to Asia and eastern Siberia populations. The American Indians resemble some Asian populations in outward appearance, in the distribution of blood group types, and in genetic composition as reflected by molecular data, such as DNA (Cordell, Paleoamericans). Stone and Dillehay believe the indigenous peoples eventually populated the Americas occurred in three separate migrations. The largest of these groups is referred to as the Amerind (Paleo-Indians). The Amerind, which includes most Native Americans south of the Canadian border, commenced around 11500 B.C.. A second migration called the Na-Dene occurred between 10000 B.C. and 8 000 B.C.. Even though at this point the Bering Sea separated Siberia and Alaska, it was only three miles wide in some places. The Athapascan speaking populations of Canada and the United States belong to this group of migrants. The Apache and Navajo in the southwestern United States are from the Athapascan migrants. The third migration around 3000 B.C. included the Aleuts and Eskimos of Alaska, Canada, and the Aleutian Islands (Taylor). Archaeologists have established humans were living in rock shelters at the southern tip of South America by 12500 B.C.. In his book Guns, Germs, and Steel, Jared Diamond notes if Native Americans moved southward from the Plains area of North America at a rate of eight-miles per year they would reach Patagonia within a thousand years. Based on this, the earliest arrival there by migrating Paleo-Indians would be 10500 B.C.. If the 12500 B.C. dating is correct, the only way these people could have gotten there was by some type of watercraft. Archeologist Jim Dixon believes costal migration from Siberia to the tip of South America began as early as 14000 B.C.. Monte Verde, a well-studied site in central Chile, is dated at 12500 B.C. (Dillehay, Paleoamericans) There is evidence of interaction between the peoples of Americas and Europe long before Christopher Columbus discovered America, as well as, indications of direct contacts between Polynesian cultures and those in the Americas. Most scholars accept the influence of Polynesian and even Asian cultures on pre-Columbian American cultures, but many are skeptical of African or European influence...this is hard to understand.
As with all “scientific discoveries” like these, they are subject to interpretation, as is the arrival of early humans...the dates varies from 50000 B.C. to 11500 B.C.. The Paleo-Indian period is defined by three cultures: Clovis, Folsom, and Plainview (Plano). The ice free corridor in the Yukon Valley allowed animals and the Paleo-Indian hunter-gathers to migrate onto the grasslands south of Edmonton, Canada. This grassland (Great Plains or Prairie) stretched from Edmonton, Canada to the tree line in central Texas. On the west, it was bounded by the Rocky Mountains and on the east by the tree line along the Mississippi River. The Great Plains covers an area close to 500 million acres. Afraid to venture out on the prairie with its violent storms and lack of shelter, the Paleo-Indians followed stayed close to the east side of the Continental Divide as far south as Texas. With plenty of game in this vast area, the majority of the Paleo-Indians remained there for centuries. This does not mean that all Paleo-Indians came this far south, but from the number of Paleo-Indian sites in the area, the majority of them did. As several species of large herbivores become extinct, the Indians broadened their hunting areas along the edges of the prairie in search of game.
Clovis Indians 11,500 B.C. - 10,900 B.C. In 1929, a spear point was found imbedded with the skeletal remains of mammoths near Clovis, New Mexico. The Paleo-Indians that occupied this site were classified as Clovis Indians. This classification was based primarily on the lithic points found there.
Clovis points are typically relatively large with single or multiple flutes. The grooved or fluted area rarely extend more than a third of the way up the body. Many Archeologists believe the Clovis Indians are the first known group of people to populate the Americas. Dating back to 11,500 B.C., isolated Clovis sites have been located in North America from Alaska to Panama. As more Paleo-Indian sites were located, archeologists set up a stringent criteria to qualify as a Clovis site. Any site not meeting all of the Clovis criteria was not considered as being early than Clovis. Despite this "stringent criteria" there is growing evidence of small groups of people in the Americas long before the Clovis Indians. The next three paragraphs are paraphrased from the Pennsylvania Archeological website. Meadowcroft Rockshelter in Washington County, Pennsylvania dates to at least 16250 B.C. and contains artifacts similar to those found in Siberia from the same time period. The fluted Clovis point has not been found at Meadowcroft or in Siberia...if a Clovis point is found, this does not mean a Clovis Indian was there, any Indian finding a Clovis point would keep it. Other sites with early dates are: Cactus Hill in Virginia 16200 B.C., Topper in South Carolina 16000 B.C., and Monte Verde in Chile 12500 B.C.. These sites represent evidence of an early migration. Because there are so many sites dating to the period from 11500 to 10500 years ago, it is hard to imagine Clovis Indians would appear so quickly without a Pre-Clovis population in place (Pennsylvania Archeology). Many Archeologist do not accept these pre-Clovis sites because they do not meet all of the archeological criteria established for dating Clovis sites.
The Paleo-Indian tool picture is taken from the Pennsylvania Archeology web page, which is an excellent site. These pictures demonstrate a real problems with dating sites and is one of the reasons some Archeologist reject pre-Clovis sites based on the type of "tools" found. Finding pieces of flint used as knives or scrapers does not mean they were chipped by Indians. The natural flaking of obsidian results in sharp pieces, even with thumb or finger grooves; these pieces can be used to cut or scrape hides. The flaked obsidian pictured above was picked up off of the ground near Kilgore, Idaho last summer. The age of "tools" found in archeological sites is based on the level of the dig and other material found at the same level i.e. charcoal. The problem is the charcoal may be washed or blown the shelter from a 16,000 year ago forest fire. There are hundreds of Clovis sites in North America, but only a few sites pre-date the Clovis Period. Living in small hunter-gatherer bands, the Clovis Indians followed primarily herds of mammoth and mastodon for about five hundred years, and then according to some archeologists, abruptly disappeared. The Clovis disappearance coincided with the mass extinction of the Ice Age animals, such as the mastodon and wooly-haired mammoth. It has been postulated by these archeologists over hunting by Clovis Indians contributed to this mass extinction of Ice Age animals. This brings up a couple of points to consider:
Did the Clovis disappear, or did they adapt a new style of fluted point and become classified as Folsom Indians? Folsom Indians 10,900 B.C. - 10,200 B.C. Another Paleo-Indian site found near Folsom, New Mexico had different projectile points. These supposedly new Indians were promptly named Folsom. Points from the Folsom period are found with the remains of the large plains bison rather than mammoths dominate the Clovis kill sites. The Folsom Indians used a smaller, thinner, fluted point than the Clovis point. These small points were developed to use with the Atlatl (spear thrower). The spear point from an Atlatl could be thrown several hundred feet with great accuracy. The Atlatl remained the hunting weapon of choice for the Paleo-Indians and Archaic Indians of the southwest until the introduction of the bow and arrow around 100 A.D.
The Plainview, or Plano, period followed the Folsom culture, and lasted from 10,250 B.C. to 8,000 B.C.. The earliest Plainview points were delicately flaked spear point without any fluting.
The Paleo-Indians of the Plainview Period were associated primarily with the smaller woodland bison migrating from northern Mexico; these were the first Indians to drive animal herds off cliffs and use grinding stones to grind seeds.
During the Plainview period several other points were found, such as, the Cumberland 10,000 B.C. - 8000 B.C. and the Dalton 8500 B.C. - 7900 B.C. The dates for the Paleo-Indians are not set in stone. For some bands the dates could vary a few hundred years either way. This applies to the Archaic Period as well. Archaic Period - 8,000 B.C. to 1,000 B.C. The Archaic period is further broken down into several period. The period from 6500 B.C. to 1200 B.C. is referred to as the Desert Archaic. The Barrier Canyon Indians emerged out of this period. The Desert Archaic Indians were basically hunter-gatherers with more reliance on gathering seeds, berries, and nuts. The Mogollon, Hohokam-Sinagua, and Anasazi cultures developed out of the late Desert Archaic period which is considered from 1200 B.C. to 100 A.D. The arrival of corn from Mesoamerica signaled the end of the Desert Archaic Period.
Woodland Period - 1,000 B.C. to 800 A.D. Native Americans hunted, fished, planted crops and created elaborate stone tools during this period which is sometimes referred to as late Desert Archaic. Ground was cleared to plant “the three sisters”: corn, beans, and squash from Meso-America. Relying more on agriculture made it possible to stay in more permanent villages. This led to the develop of pottery and the establishment of trade networks between various groups of Native Americans including those from Mesoamerica. Mississippian Period - 800 A.D. to 1600 A.D. During this era, Native Americans cleared land by girdling (removing a ring of bark to stop growth) or using fire to clear the land. Wood products were used to build more permanent structures during the Mississippian period. One last point: One of the most confusing things about Archeology is Archeologists...no wonder there is so much disagreement...they can't even agree on a dating system.
Radiocarbon dating is based on a lot of assumption about the half-life of Carbon 14 in relation to the stable Carbon 12 , such as atmosphere, type of soil, weather, etc,. These factors produce a relatively wide margin of error in Carbon 14 dating. Another limitation to Carbon 14 dating is it applies only to organic material such as bone, flesh, or wood. Radiocarbon dating can't be used to date rocks i.e. Indian points, petroglyph, or pictographs. Basically Archeology is...Assumptions based on Association...with few scientific facts to back up the assumptions. If adjustments for political correctness are not bad enough, the term years ago frequently follows the date. Does this mean from today, from 1950, or from 2,008 years ago??? For a candid discussion of archeologists read the Waldo Wilcox comments on the Range Creek Fremont study in the August 2006 National Geographic. There are more questions than answers in the settling of the Americas. The one thing known for certain is the Americas were populated by people...some by land, some by boat...how, when, or why is primarily speculation with little consensus among the schools of Archeology.
