Native American Civilizations
Figure 1.--The major Native American civilizations are familiar to the public, but there are many civilizations that are less well known.
This boy is an Aymara.
The Aymara people dominated the Lake Titicaca Basin of Bolivia and Peru.
The were conquered by the Inca in the 15th century, but are still the dominant ethnic group in the area.
The photographer was Raul Soria P.
Native American civilizations are difficult to arrange chronologically.
The three best known civilizations (Maya, Aztec, and Inca) are contemporaneous with Medieval Europe.
There were civilizations that were ancient at the time these and other civilizations flourished.
Teoteauacan was an ancient ruin at the time of the Aztec.
While the chronology of the Maya, Aztec, and Inca are fairly well developed, the dating of the early civilizations and the early history of human settlement of the Americas is a matter of some controversy.
The Native Americans civilizations of the New World are unique in that they developed in isolation from the other great world civilizations.
Some of the great Old World civilizations had extensive contacts.
Others had only minimal contact, but contact nevertheless.
The contact with the Europeans beginning in 1492 was in many ways to Native Americans like visitors from outer space would seem to our modern world. [West]
Some early attenpts at racial classifications identified Amerindians as a separate racial group. There is now no doubt that Ameriindians are a Mongoloid sub-group, having crossed over the Bearin Sea ice bridge (about 15,500-11,000 years ago with other waves following). Siberian hunter-gather tribes migrated over the ice bridge to what is now alaska. Then with rising temperatures became isolated in the Americas. (Interestingly, horses made the reverse journey.) Some of these proto-Indians stayed in the Arctic (the modern Inuits and Eskimoes), but others moved south into milder more productive areas. Here there is considerable debate as to just how because the Ice Age shelf blocked their passage south for some time. The original proto-Indians left no archeological evidence of this crossing. There were hunter-gather people ad the ice-bridge is now under water. DNA evidence, however, confirms the Asian origins of the vast majority of Native American people. The issue, however, is more complicated. And the formerly widely accepted assessment of the peopleing of ameruc has been called into question with findings of very early Amerindian sites, uncluding site in southern Argentina and Chile. Some DNA studies have also complicated the story of the peopling of the Americas. Researchers have detected some Caucasoid elements. This is largely unexplained, but presumably relates to the Caucasoid populations which at the time of the Bearing Sea crossing dominated Central Asia, although there are other possibilities. We have also notice claims that Polynesian elements have been detcted. Both of these non-East Asian elements are still being assessed, but they do not alter the fact that Native Americans are fundmentally a Mongoloid people. Th DNA evidence, however, can offer valuable insights into the process of peopleing the Americas a process for hich there is little or no arheological evidence. Another interesting aspect of Native american people. We note tribes with different physical characteristics and features. This may related to the various levels of Caucasoid and Polynesian admixtures as well as the characteristics of the tribal peoples who made the crossings. One author writes, "The common argument is that When I look at the various pictures of Native Americans, however, most of them do not look like neo-mongoloids found in Honshu Japan, Korea, northern China, Mongolia, and Siberia. Their faces look like archaic mongoloids who have still significantly retained old caucasoid-like features (especially North American natives)." Enviromental adaptions may be even more important. The Native american people of the andes like Peuvian/Bolivian Quechua and Aymara look like Tibetans, with obvious adaptation to living at high aditudes. Some go on to say that that they have "more Central Asian features (Turkmen, Uzbek, and others). While the Amazonian Indians resemble Southeast Asian paleo-mongoloid tribal populations." We are less sure about that, but DNA work may eventual provide insights that can identify just how the America were peopled.
Our understanding of history gradually unfolds over time.
It is commonly true that what seems very obvious to contemporary people looks very different a generation later.
We often change our views with the benefits of hindsight.
Improved historical methods have also assisted us.
No where is this more true than the historical assessment of Native Americans.
Virtually everything we thought we knew about Native Americans a generation ago has been proved wrong.
And here we are not talking about Hollywood depictions.
We are talking about the work of respected archaeologists and anthropologists who dominated Native American studies.
In the past two decades we have found that Native Americans have been present in the Western Hemisphere far longer than previously thought and had developed a far more sophisticated and complex societies than previously believed.
The pre-Colombian population was also much larger than previously believed, although there is still intense differences as to actual population levels.
But the most serious mistake in our assessment of Native Americans has been the commonly held belief that they lacked agency and had little impact on the environment.
The ruins studded throughout Meso-America and the Peruvian Andes stand in testimony to those achievements.
Achievements in agriculture, astronomy, engineering, mathematics, textiles, and writing,
are impressive.
Surely one of the most significant accomplishments of any society over time was the domestication of corn and the potato.
These two accomplishments changed Europe more than any other technological achievement making possible a population explosion.
Europeans were so amazed by the technological achievements, especially the n monumental architecture of Native Americans, that a long series of popular authors have ascribed these achievements to other peoples including aliens.
HBC is not prone to politically correct group speak, but this idea that Native Americans were incapable of high-cultural achievements is pure and simply racist.
There is a corollary line of thought.
That Native Americans live in harmony with their environment without harming it or leaving a significant footprint.
This line of thought has a long history, symbolized by Rousseau's noble savage.
We now know that Native Americans significantly shaped their environment.
Some believe that the Great American prairie was significantly expanded by Native American use of fire.
And in some cases Native American cultures perished because they did mot manage their environment well.
The current theories on the collapse of Teoteauacan and the Maya are essentially environmental mismanagement and scientists studying many other Native American cultures are coming up with similar theories.
(15,000-8,000 BC)
The Native American people are of Asiatic descent.
They were nomadic hunter-gatherers who migrated to the American continent over a Bearing Sea land-ice bridge at the end of the last Ice Age probably about 12,000 years ago. After crossing the Bearing Sea ice bridge, the Native American people moved south and east until populating the entire Western Hemisphere as far south as Tierra del Fuego in South America. Some archaeologists believe that the migrants moved south along the coast of Alaska through an ice free coastal corridor.
Other archaeologists challenge this theory.
There is no real doubt that Asiatic migrations took place.
(Some suggest European or Polynesian migrations, but the archweological evidence is virtually nil.)
While the Bearing Sea crossing is accepted by most all serious archaeologists, the precise timing and process of these migrations is a matter of considerable scientific debate.
Some contend that the migrations may have begun as early as 15,000-20,000
years ago and may have involved people that moved by sea as well as by land.
These mariners did not have large raft, but could have made short hops in small craft from island to island as they moved south.
There is little archaeological evidence for this, but most of their settlements would today be underwater. [Koppel]
It now appears that there were several successive waves of migrations.
This has complicated Native American anthropological studies.
We now know that migration continued well after development of indigenous societies in both North and South America.
This means that migrations took place well after civilizations for which we have archaeolgical evidence.
This had confused early anthropologists who assumed that the migrations preceded the early cultures which they found such as the Clovis Point people.
The stone tools found at Clovis, New Mexico are believed to fate to about 9000 BC.
The Clovis Point people were once thought to be the earliest American culture.
Other cultures have since been found much further south in South America. [Koppel]
(8,000-1,500 BC)
The Archaic period in Native American culture is much shorter than the the Paleo or Proto-Indian era, although this is debated depending on just when the Bearing Sea crossing is dated.
ThevArchic stage can roughly be dated with the disappearance of the Clovis people (roughly 9,000 years ago.
We know, howver, much more about them because of the greater number of archeological sites .
The Proto-Indians lived in a still rather cold environment with the Ice Age even as the glacial/ice sheet coverage began to recede.
Archic Indians experienced with the end if the Ice Age a changing environment featuring a warmer, but more
more arid climate.
Theu also had to adapt to the disappearance of the last megafauna. ['Blame ...']
This required a major cultural adaptain.
With the rise of sea levels rose, river deltas became flooded proding new resources to exploit.
With the warmer, grier climate, vegetation changed which led to more change.
As the Pro-Indians adaoted to these changes they became what is not described as Archic-Indians.
Archeologists estimate the time frame from about 8,00-1,500 BC.
Most Native American people at this time continued to be mobile hunter-gatherers, but individual groups began to work with resources available locally rather gthan followung migratory heards.
Over time destinct regional patterns (Southwest, Arctic, Poverty, Dalton and Plano traditions) developed.
And such regional cultural adaptations became standard.
Hunter and gathering did not disappear, butb mixed economic activity appeared, utilizing small game, fish, seasonally wild vegetables and a range of plant foods. [Fiedel]
This varied greatly from group to groupand regionally as did the local resources to exploit.
Many groups continued to primarily exist on big game hunting, but hunting traditions evolved.
Hunting became more varied and hunting more sophisticated. [Pielou]
And there is evidence of increasingly sophisticated cultural organization. Archeologists have found some artifacts and materials in burial sites suggesting definite social differentiation based upon status. [Imbries]
And by the end if the Archic stage the cultural advances had akready begun in the major centers of advanced cultural development, socially Meso-America abd the Andes.
It is from Archic Indians that the modern tribes evolved that the Europeans encountered beginning with Columbus' voyage (1492).
Chronology
Native American civilizations are difficult to arrange chronologically.
Only a geberation ago, archeologists thought they had the whole chronolgy of New World well documented based on the Clovis First theory.
Considerable work in Meso-America developed a good understanding of the many didderent civilizations.
Teoteauacan was an ancient ruin at the time of the Aztecs.
While the chronology of the Maya, Aztec, and Inca are fairly well developed, the dating of the early civilizations and the early history of human settlement of the Americas is a matter of some controversy.
Information is especially limited on the Olmec which appears to have been an early civilization of great importance.
articularly unsettling in dating Native American people is the discovery of the well earliest dated human settlement is in southr Chile near Puero Montt--Monte Verde.
And there are other unexpected sites being found.
nd if that was no bad enough, the whole issue of Anazoniab settlement has hardly been touched.
Agood deal is know about Meso-America.
The earliest known civilizations in South America appeare along the coat in northern Peru--surprising because the area is so arid.
And from an early pooint w notice amazinian influences, although next tonnothing is known about advanced civilizaions in the Amazon.
Many Native Americans never evolved beyond the hunter-gather stage.
Others civilizations developed sedentary agriculture.
The first evidence of settled habitation is first noted in modern Mexico during the Archaic period
Here we note corn cultivation, pottery and stone tools.
The first sophisticated civilization in Meso-America was the rise of the Olmecs around 1500 BC - 300 AD during what is known as the Pre-Classical period.
The Olmecs settled on the Gulf of Mexico Coast of central Mexico.
Very little information has, however, been learned about them as is the case of other early Meso-American civilizations.
Many archaeologists believe that it is the Olmecs that developed many of the characteristics features of Meso-American cultures, including sophisticated calendars and hieroglyphic writing.
Archaeologists have not definitively developed the relationship between the Olmec culture and the Maya and other Meso-American peoples.
The three best known of these agricultural civilizations (Maya, Aztec, and Inca) were contemporaneous with Medieval Europe.
These civilizations are well known because they are the civilizations that the Spanish encountered.
The three great civilizations were brought to am abrupt end in the early 15th century by Spanish Conquistadors.
Native Americans, even the great civilizations of Meso-America and the Andes, were stone age people.
This is no to denigrate these people and their achievements, it is simply a statement of ract.
This made their phomenal achievements even more remrarkable.
The stone age is usually defined as the era of human developent in wgich stone tools and weapons were used.
Many advanbces could be mase during the stone age, including achievements in fiels often associate with more technologically advanced eras.
The key technological development leasing to more advanced periods is metalurgy.
And here the technological advance was the ability to geberate high temperatures. The first step ws the Bronze Age nd finally the Iron age.
Native american peoples had begun to nake some achievenents in metlurgy, but primarily work in precious metals like gold nd silver, metals with low melting points.
They were on the cusp of the Bronze Age, but never made this vital transition.
This is astonishing because the agricultural societies of the Old World had all energed from the Stone age by 2000 BC.
Academecians tend to stress the achievements of Native americans, especially because its fits the modern ideological docrtines of cultural relativity and resistance to recognizing the achievements of the West.
And thius the failures of Nativive amrican civilization such yhe continued use of crude stone tools, kilmited mralurgical technology, failure to develop the wheel, and lack of any movement toward scientific descipline.
Rather than trying to make the cultural relativity case, the question that should be asked was why Native amerivans were so far bhind the Old world (boith the West and China).
We suspect that the reason so many scholarsfail to ask tghis question is that it leads to answers that do not ideological conform to the desire to undermine the great achievements of the West.
And part of this answer is isolation.
The Native American civilizations of the New World are unique in that they developed in isolation from the other great world civilizations.
Some of the great Old World civilizations had extensive contacts.
Others had only minimal contact, but contact nevertheless.
Some archeologists have postulated contacts with Polynesians and or Africans and cthere are some intreaguing indicators, but these contacts have yet been proved with DNA evidence.
Whether there were such contacts,
it is clear that Native Amnericans of the New World were largely isolsted from the Old World.
The contact with the Europeans beginning in 1492 was in many ways to Native Americans like visitors from outer space would seem to our modern world. [West]
The Native American civilizations of the Americas lived in almost complete isolation from the rest of the world.
This was true to such an extent that many Native Americans thought the Spanish might even been gods.
One of the many fascinating questions of history is how Cortez, Pizarro, and other Conquistadores defeated empires with millions of inhabitants with pitifully small armies.
One reason is the cultural isolation of Native Americans.
One historian writes, "Isolation insulates a culture from a wider field of comp and in the long run this is unlikely to be in its advantage." [Cook]
Here the danger in part biological.
Isolated communities do develop resistance to major disease.
The European Conquistadors brought with them diseases like smallpox that proved more deadly than the European plagues of the 14th century.
Another matter is technology.
The technological progress in human civilizations do not follow a prescripted pattern.
A society my be advanced in some areas and very primitive in others.
The Native Americans had sophisticated mathematics and calendars, but did not develop the wheel.
Europe on the other hand shared technological advances directly or indicrectly with other civiliizations (especially the Arabs ad China).
While the contacts might be tenuous, such as over the Silk Road, might have been tenuous, but it existed.
The contribution of Chinese technology to European history and civilization is astonishing.
The isolation of Native Americans put them at a great disadvantage to the Spanish.
As a result, the Native Americans could not match the technology of the Europeans.
Cultural Diversity
A stunning characteristic of Native Americans is their cultural differences.
Perhaps this is a reflection of the relatively small numbers of Native Americans in a vast territory.
There were densely settled areas that did produce high culture, but the general pattern was sparse settlements in a vast landscape.
There was more cultural differences in the Americas than was the case of the New World.
Language is a good reflection of culture.
Much of the world population speak Indo-European languages which developed from a common source.
There is no such dominant language among Native Americans, perhaps a reflection of waves of migration.
Rather there are many language families in both North and South America.
Ethnologists have written at length of this cultural diversity.
Some authors have found common threads among Native Americans.
One, Some see a pervasive spirituality among Native American peoples.
Two, Some see a different attitude toward nature.
Europeans wanted to harness nature.
Native Americans lived in harmony with nature.
Native Americans also did not have a concept of land ownership.
Three, The Native Americans were decidedly ethnocentric.
Often their names were "The People".
There was no concept of racism, but there was cultural chauvinism.
Whiles and blacks could be accepted into the tribes if the new comers accepted the tribal culture.
The Native American civilizations were brought into contact with Europe beginning in the late 15th century by the European explorers .
Christopher Columbus was the first in 1492.
The initial impetus was trade with the Spice Islands and China, but as rumors of a fabulous cities of gold circulated in Europe, gold became an increasing allure.
While there was no El Dorado, Conquistadors found civilizations with great quantities of the precious metal.The great European voyages of discovery of the 15th and 16th centuries were fundamentally economic enterprises.
They were conducted by the European countries of the Atlantic coasts to establish direct trade contacts with China and the Spice Islands (Indonesia) that was being blocked by Byzantium/Venice and the Arabs. At the time, trade in silk, porcelain, and spices from the East carried over the Silk Road had to pass through Turkish, Arab, Byzantine, and Italian middleman, making them enormously expensive. The crusaders failed to break the Islamic wall separating still primitive Europe from the riches of the East. Circumventing the land Silk Road and the sea Spice Route would have profound economic consequences for Europe and the world.
The voyages of Columbus and the other
had profound consequences for both Europe and the world.
Following on Columbus' voyages, Spain rapidly
began establishing colonies.
At first Columbus and the Spanish did not realize that they had chanced upon an entirely new continent--the Americas.
They thought it was India and thus called it the Indies and the Caribbean Islands have become known to us as the West Indies.
Spanish colonization was at first in the Caribbean and extraordinarily brutal.
The native Americans on the islands were for the most part exterminated.
Next the Spanish looked to the mainland where rumors described Native American civilizations of vast wealth.
This led to Diego Cortez's .
Balboa had earlier found the Pacific across the Isthmus of Panama.
This led to Hernando Pizarro's .
flowing from the Americas made Spain a European super-power and financed the Great Armada.
The most significant impact of the conquests, however, may well have been the introduction of the humble
to Europe from Peru.
Population
The population of the Americas before the European conquest is unknown.
It is also a hotly debated subject in ethology.
There are widely divergent estimates.
These estimates vary from about 15 million to as much as 150-200 million people.
For many years, historians tended to favor very low estimates of the pre-Conquest native American population.
Modern historians are likely to adopt the middle ground of about 80-100 million people, but many still accept the lower range if the estimates.
There is at this time no real definitive evidence as to the pre-Conquest population of the Americas.
This is interesting, because a population of that magnitude would approximately equal that of Europe at the time.
Each of the three great Native American civilizations were conquered with surprising speed by the Spanish Conquistadors.
Even so, the civilizations had
profound and offered ignored impact on Europe.
The gold and silver which flooded into Europe in the 16th century had a major impact on the European economy.
Many new agricultural products including cacao, corn, potatoes, tomatoes, and others were introduced to Europe.
Many of these crops or products are of considerable importance.
The lowly , however, had a huge impact on European society.
Farmers found that the amount of food produced per hectare with potatoes was far greater than with any other crop.
This meant that European agriculture could support a much larger population and was a major factor in the growth of European populations after the 16th century.
Another major crop was , although the full potential of this crop only came to fruition in the 20th century.
The Spanish destroyed vast quantities of art work for religioius reasons.
This significantly limits the amount of contemporary images.
There are many images from the Native American civilizations.
Maya murals have been found in tombs that the Spanish never found.
There are also metal objects and pottery.
We have been unable to find contemporary Native American art depicting children and their clothing.
There are modern recreations, but as always there is the problem of historical accuracy.
Besides the , there were many other Native American tribes in South America. Many were centered in the Andes or along the narrow coastal plain to the west of the Andes.
he Inca highly civilized.
The Inca conquered many of the tribes in or along the Andes from Colombia south to Chile.
There were also tribes to the east of the Andes.
The primitive tribes in the Amazon still exist, although there numbers are now very small.
One such group is the .
One ongoing mystery is that Spanish sources report a very substantial population in the Amazon basin during the 16th century.
Francisco de Orellana set out on a quest for gold and soon found himself just trying to survive.
He was the first European to travel the entire length of the Amazon and he reported a huge population of very productive farmers.
Historians at first dismissed the Spanish account as fanciful.
Modern anthropologists have begun to reassess this judgment.
Some believe there indeed once was a very large population in the Amazon basin practicing sophisticated agriculture.
Central America in geographic terms is part of North America. Etnographic studies of North America commonly focus primarily on American and Canadian tribes and those of northern Mexico. Central America is often not considered. This is in part because American anthropolgists have focused primarily on those tribes found within the United Satates. Also the Maya dominated much of northern Central America. The Central American tribes south of the Mayan areas in the north were relatively small and primitive. Most disappeared as a result of Spanish slave raiding and exposure to European diseases. This was the same fate as the Arawaks and Caribs in the Caribbean. One of the few tribes to survive are the Cuna. Unlike Centrl America, the Maya never settled the Caribbean, although they are known to have traded with the people of western Cuba.
The Caribbean were heavily settled by the Arawaks, Caribs, and to a lesser extent the Chiboneys.
Historians debate the relationship between the Arawaks and Caribs.
Some theorize that the differences between the two people were a Spanish colonial convention rather than real differences. These people were descimated by the Spanish early in the colonial era through both ill-treatement and disease.
The Spanish encountered the great Native American civilizations in Meso-America and the Andes.
There were many other Native American cultures in North America.
These tribes were mostly nomadic hunter gatherers, but some practiced agriculture to varying degrees.
Native Americans, in part because of the horrendous treatment by white Americans as well as the exposure to European diseases, now comprise only a small part of the American mosaic. It is a rich, colorful tradition, no matter how small. Native American dress is showcased at powwows and other gatherings held annually throughout America.
The term holocaust is today most commonly used to describe the NAZI genocide of European Jews and others.
There have been other terrible holocausts in history and not all of them man made.
There have been terrible epidemics, the most familiar to Western historians is the bubonic flu epidemics which ravaged medieval Europe.
Perhaps the most deadly disease epidemics in history occurred in the Americas in the wake of the European conquests.
By a quirk of evolutionary history, Native Americans had no resistance to many of the most deadly human diseases.
This was because of the Great Extinction of the Pleistocene Era, the America were left without large mammals which could be domesticated.
In Europe and Asia, the advent of civilization brought domestication of many large mammals (cats, dogs, cows, horses, oxen, pigs, sheep, etc).
People thus lived in close proximity to these mammals.
Peasant family commonly lived with livestock.
Most of the most deadly
are diseases which have mutated from animal diseases to human diseases (influenza, measles, small pox, and others).
Over time Asians and Europeans developed an immunity to these diseases, but Native Americans without these large domesticated mammals did not.
Thus when the diseases were introduced by the Europeans, Native American populations were ravaged.
Such diseases were, for example, a principal reason in the Cortez's defeat of the Aztecs.
Historians believe that as much as 90 percent of the Native American population perished.
Clothing varied dramatically among the different Native American peoples.
The variations are such that it is difficult to describe any garments that were shared among Native Americans.
There were garments that were widely worn regionally such as moccasins in North America and ponchos in the Andes.
Thus we have attempted to address clothing either regionally or on the individual tribal pages.
Perhaps the most common element was animal products for decoration such as teeth and feathers.
But this was not distinctive to Native Americans, these items were also used by stone age people on other continents.
There were no garments common among all Native American peoples.
The reason for that is that Native Americans were tremendously diverse culturally.
Some Native Americans did not wear clothes such as the Tainos that Columbus first encountered in the Bahamas (Lucayas).
The Taino on Hispaniola were somewhat more advanced, but clothing was still very basic if worn at all. In contrast the Inca produced some of the finest woven textiles imaginable.
The Spanish were shocked by the lack of clothing among the Taino.
And along with
Christianizing
them attempted to get them to wear clothing.
Missionaries on Hawaii and elsewhere in Polynesia attempted to do the same.
Christian missions played an important role for the spreading of European clothing and sense of modesty.
In spite of his effort, clothing was seen as something unconnected with the local culture.
Their success in large measure reflected the degree of control.
Thus the Spanish with the Native Americans organized into ecomiendas could require Native Americans to adopt Western clothing.
The Native Americans isolated in remote areas of the Amazon were able to maintain their cultural patterns.
"Blame North America megafauna extinction on climate change, not human ancestors," Science Daily. (2001).
The debate over the extinction of the megafauna cintinues.
Certainly climate change is a possibility as is the arrival of Proto-Indians.
Unfortunately these assessments have to betreated with caution.
Climate change is the flavor of the day and some academics have allowed their passion for fighting climate change to affect their academic commitment to dispastiontely assess evidence.
Readers thus need to use some caution in reasi
