Anasazi News

A few, a very small minority, hold that people could have reached the new world from Europe by following a north Atlantic ice shelf. Represented by archaeologists Bruce Bradley and Dennis Stanford, this minority position emphasizes similarities between Clovis artifacts and those created by the Upper Paleolithic Solutrean culture. The similarities include the shape and flaking of Clovis points, use of ivory shafts and points, and presence of needles and shaft straighteners.

Kris Hurst has posted a nice synopsis of the evidence supporting the Solutrean-Clovis connection along with a number of helpful links.  Incidentally, although Kris does not mention it, there is a modest amount of genetic evidence suggesting an Indo-European migration to North America. See Chapter One of The Anasazi Guide for a brief summary.

Readers may also notice a substantial oversight in the article--it doesn't mention the cultural differentiation that had begun to splinter the Anasazi world long before the ultimate collapse. Although we use the word, "Anasazi," as if referring to a single coherent community (aka, "tribe") linguistic evidence suggests the people did not think of themselves as members of a common group. Pueblo and Hopi descendants speak nearly a dozen distinct languages and I suspect the cultural differences made it easy for the ancestral people to engage in conflict with people where were not like themselves. 

Initially reported in Science on April 3rd, the story was promptly picked up by Fox News, the Discovery Channel, the New York Times, and the Washington Post. And, you can watch an interview with Dennis Jenkins, the principal investigator, on The Archeology Channel.

Chapter One of The Anasazi Guide explains why this finding has attracted so much attention and Kris' Archeology Blog has a nice synopsis along with some additional links.

Using isotopic ratios of hydrogen and copper measured by a secondary ion mass spectrometer, Hull and her colleagues demonstrated that it is possible to uniquely characterize turquoise deposits. They analyzed twelve turquoise mines and defined 10 turquoise provenance regions. In addition, they found that 13 of 17 artifacts recovered in northwestern New Mexico "fell into several distribution patterns of characterized source regions, suggesting that turquoise was obtained from several source areas and moved over long distances."

You can read the abstract and purchase the article, "A new approach to determining the geological provenance of turquoise artifacts using hydrogen and copper stable isotopes," or view a capable summary with links on Kris' Archeology Blog.

The Anasazi emerged from a group of hunter-gathers who migrated to the "new world" from Asia. Chapter One of  The Anasazi Guide summarizes what we knew about the peopling of North America just a year ago. Since that time, genetic, linguistic, and archaeological studies have filled in many gaps and several critical publications are noted below; see stories reported on March 12, 2008; March 4, 2008; February 4, 2008; and November 27, 2007.

Keeping abreast of the "breaking news" can be a bit of a headache, but an article published today will simplify the task for you. Ted Goebel and colleagues, "The Late Pleistocene Dispersal of Modern Humans in the Americas," Science review the existing data and conclude that "evidence implies dispersal from a single Siberian population toward the Bering Land Bridge no earlier than about 30,000 years ago (and possibly after 22,000 years ago), then migration from Beringia to the Americas sometime after 16,500 years ago." Nonsubscribers can read the abstract and purchase the article, but  a  capable summary on Kris's Archeology Blog will save you the cost and provides a number of interesting links.

Genetic information about the first people that migrated to North America has been relatively sparse. The result has been a less than complete picture of the origins of the people we call Anasazi. The inadequacies have been at least partially resolved in a recent study by Alessandro Achilli and colleagues, "The Phylogeny of the Four Pan-American MtDNA Haplogroups: Implications for Evolutionary and Disease Studies ."

Drawing together genetic sequences previously cataloged in various publications, Achilli and colleagues demonstrate that 95% of all living Amerinds are derived from just six (6) ancestral mothers who lived between 18,000 and 21,000 years before present. Significantly, the MtDNA characteristics of the six lines are not present in Asia lending support to the claim that the people evolved in Beringia--a now submerged land mass between Siberia and North America (see the news report dated February 14, 2008 below). In addition, the findings are moderately controversial because they raise additional questions about the "Clovis first" hypothesis.

The Achilli study is available online, but many readers will find it difficult reading. Helpful and relatively complete synopses have been reported by The Washington Post and Fox News, and Chapter One of The Anasazi Guide includes a helpful discussion of the genetic evidence. 

Vajda has demonstrated that Ket, an "old world" language spoken by a few hundred Siberians living along the Yenisei River in western Siberia, is closely related to the languages spoken by many Athabascan tribes including the Tlingit, Eyak, Navajo, and Apache.  While he stops short of asserting a genetic link between the peoples, others have provided that evidence (see stories reported below on February 14, 2008 and October 25, 2007). 

The Anchorage Daily News has published a readable summary of his work and its significance, and his recently revised essay is available online.  Chapter One of The Anasazi Guide includes background that will help you put this research in context.

1. The root stock of Native American people emerged in Asia at least 50,000 years before present,
2. A portion of this population moved to Beringia--a now submerged land mass between Siberia and North America--and remained there for a considerable period of time, and
3. About 15,000 years before present, this population moved to North America and expanded rapidly to fill the continent.

Since publication, this article has attracted some interesting and well-informed comments.  The thread is available on PlosOne.

While museums and other organizations have grumbled a bit about returning artifacts, substantial controversy arose in 2000 when scientists opposed returning Kennewick Man to Indian groups of questionable affiliation. In response, two proposed wording changes are now before congress.  

Kris Hirst  has a pair of posts on Archeology.com that summarize the proposed changes as well as responses to them. If you haven't followed the controversy, I recommend that you read her first post before moving on to the second. Links in both posts provide useful background information about the law and controversy regarding its application to Kennewick Man.

As part of an agreement with the Tesuque Pueblo which claims cultural affinity to the recently discovered pueblo, city officials closed the excavations to public viewing and retained artifacts without study or consultation with archaeologists.

Now, the city has taken one more clandestine step; seeking to rebury the artifacts without systematic study or analysis. This peculiar, and probably illegal, procedure is reported by The Santa Fe NewMexican.

To help put their findings in context, there is a helpful summary of prior research on About.com's archeology page.

New dating of Clovis sites is even more interesting. The revised dates between--13,050 to 12,800 years before present--suggest that the culture was more ephemeral than previously believed. Whereas earlier work had suggested that Clovis spanned roughly 500 years, the revised dates roughly halve that figure and push back the dates for the Archaic era. 

The first article recounts recent news stories about the collapse of an ancient lake in North America. Dubbed  "Lake Anasazi," the lake collapsed about 8,200 years BP and dumped millions of gallons of cold water into the North Atlantic. The result was a major cooling epoch that significantly altered the climate and roughly bounds the transition from Paleo-Indian to Archaic eras.

The second article summarizes recent debates about Kennewick Man and proposed changes to the Native American Protection and Repatriation Act.

The account is a helpful introduction to the site and includes links to more detailed discussions.

A less formal summary of the study can be found on the Fox News web site. Chapter One of The Anasazi Guide includes background that will help you put this research in context. 

The article is a brief introduction to the site and you can find more information on the Center for Desert Archeology's "Visiting Places of the Past" page.

1. Migrants from Asia paused in Beringia--a now submerged land mass between Siberia and North America--long enough for mutations to distinguish them from the founding Asian populations, and 
2. Once the migrants entered the new world, the population spread rapidly resulting in relatively little genetic diversity in North and South America.

The Mesa Verde National Park Boundary Expansion Act of 2007 was unanimously passed by the House of Representatives and will now be considered by the Senate. If passed and signed into law, the bill will add 324 acres to the Park. For details, see this brief article in the Cortez Journal.

The 20th Anniversary Southwest Symposium is scheduled for January 17-19, 2008 in Tempe, Arizona. The conference will focus on three themes: Movement, Connectivity, and Landscape Change. Although the conference is conducted primarily for academics and other researchers, there are several papers that will appeal to anyone fascinated by the Anasazi:

• Wesley Bernardini (University of Redlands) and Severin Fowles (Barnard College), Becoming Hopi, Becoming Tiwa: Two Pueblo Histories of Movement
• William Lipe (Washington State University) and Tammy Stone (University of Colorado, Denver), Standing Out Versus Blending In: Pueblo Migrations and Ethnic Marking
• Jeffrey J Clark (Center for Desert Archaeology) and Karl W. Laumbach (Human Systems Research, Inc.), Pueblo Migrations in the Southern Southwest: Perspectives from Arizona and New Mexico
• Ruth Van Dyke (Colorado College), The Chaco Connection: Intervisible Landscapes
• Greg Schachner (UCLA), Ritual Places and Landscapes: Connecting Southwest People and
  Societies across Time and Space
• Stewart B. Koyiyumptewa (Hopi Cultural Preservation Office) and Chip Colwell-Chanthaphonh (Denver Museum of Nature & Science), The Past is Now: Hopi Connections to Ancient Times and Places

The paucity of news is due to timing of the archeological field season. In the spring, sites are being opened--or reopened--and many news releases describe the sites and explain excavators' anticipations. During the summer, news releases report important findings that confirm or alter researchers' expectations as well as their implications for theories and interpretations.

News releases taper off with the changing seasons, and the fall is a "slow" season. Researchers are closing sites for the winter and will soon begin the hard work of analyzing finds and composing formal reports. This work is less sexy than excavation, but it builds the knowledge base on which new theories and interpretations rely.

Don't despair. By the end of November, news releases will begin to flow again and you can expect a deluge beginning in January. 

A more complete summary reads as follows: "The early development of agriculture in the New World has been assumed to involve early farming in settlements in the Andes, but the record has been sparse. Peanut (Arachis sp.), squash (Cucurbita moschata), and cotton (Gossypium barbadense) macrofossils were excavated from archaeological sites on the western slopes of the northern Peruvian Andes. Direct radiocarbon dating indicated that these plants grew between 9240 and 5500 14C years before the present. These and other plants were recovered from multiple locations in a tropical dry forest valley, including household clusters, permanent architectural structures, garden plots, irrigation canals, hoes, and storage structures. These data provide evidence for early use of peanut and squash in the human diet and of cotton for industrial purposes and indicate that horticultural economies in parts of the Andes took root by about 10,000 years ago."

And, Nature.com has added a nice summary with the title  Ancient seeds reveal Andean crops.

Childs' version of Four Corners prehistory, already praised as a popular text, is best read as a nice if overly long travelogue. As revisionist theory prompting further study, it's timely, but the book's intended audience means the prose is often vague, the ideas oversimplified or unsupported and the agenda's emphasis on violence too biased to credit wholeheartedly.
