Etowah Mounds
Sep 16th 2011, 10:15

The site called Etowah Mounds is located on the Etowah River near Cartersville in northwestern Georgia in the American southeast, and currently owned by the state of Georgia and open to the public.

During the 11th through 15th centuries AD, Etowah was a ceremonial center and political capital of the Mississippian civilization, and deeply involved in the Southeastern Ceremonial Complex of the Lower Mississippi Valley.

Visiting Etowah today, you'll find three enormous mounds, the tallest over 60 feet. A ditch once used as a palisaded fortification is still visible, and a museum, picnic tables and riverside benches are there for the casual visitor. In addition, you will find a reconstructed wattle and daub house and a dugout canoe built to Mississippian specifications.

Pacific Coast Migration Model
Sep 15th 2011, 10:00

The Pacific Coast Migration Model is a theory concerning the original colonization of the Americas that proposes that people entering the continents followed the Pacific coastline, hunter-gatherer-fishers traveling in boats or along the shoreline and subsisting primarily on marine resources.

The PCM model was first considered in detail by Knut Fladmark, in a 1979 article in American Antiquity which was simply amazing for its time. Fladmark argued against the Ice Free Corridor hypothesis, which proposes people entered North America through a narrow opening between two glacial ice sheets. The Ice Free Corridor was likely to have been blocked, argued Fladmark, and if the corridor was open at all, it would have been unpleasant to live and travel in.

Fladmark proposed instead that a more suitable environment for human occupation and travel would have been possible along the Pacific coast, beginning along the edge of Beringia, and reaching the unglaciated shores of Oregon and California.

Support for the Pacific Coast Migration Model

The main hitch to the PCM model is the paucity of archaeological evidence for a Pacific coastal migration. The reason for that is fairly straightforward--given a rise in sea levels of 50 meters or more since the Last Glacial Maximum, the coastlines along which the original colonists might have arrived, and the sites they may have left there, are out of present archaeological reach.

However, a growing body of genetic and archaeological evidence does lend support to this theory. For example, evidence for sea-faring in the Pacific Rim region begins in greater Australia, which was colonized by people in water craft at least as long ago as 50,000 years. Maritime foodways were practiced by the Incipient Jomon of the Ryukyu Islands and southern Japan by 15,500 cal BP. Projectile points used by the Jomon were distinctively tanged, some with barbed shoulders: similar points are found throughout the New World. Finally, it is believed that the bottle gourd was domesticated in Asia and introduced into the New World, perhaps by colonizing sailors.

Metallurgy
Sep 15th 2011, 10:00

Definition: Metallurgy, when used by archaeologists, is the study of the ancient processes of producing objects made of metal, including quarrying, mine construction, and smelting.

The earliest form of metallurgy was hammering copper. Native copper was first used by Old World Neolithic people beginning about the 8th millennium BC; and by New World in South American cultures beginning between 3600 and 1500 BC.

The next step, smelting (again of copper) appeared at Catal Hoyuk in Turkey, about 6000 BC; lead appears to have been added to the metal working about this same time. Mining of native materials began about 5000 BC. The earliest gold so far is from Varna in Bulgaria, about the same time. The earliest goldworking in the Americas to date is from the Jiskairumoko site of Peru, 3600 and 1500 BC.

Archaeology: What's Hot Now: Ancient Mesoamerica Worldview

Ancient Mesoamerica Worldview
Sep 15th 2011, 10:00

The people of ancient Mesoamerica shared a unique, yet complex view of the world around them. The world was understood as both square and round-shaped, but it was also perceived as a turtle or caiman floating on a primordial sea. The world was divided into four directional corners with a fifth central point. Mountains, caves, and water combined were a foundational aspect of this geography that divided the world into horizontal and vertical layers. Many times these features were depicted as alive, a trait that continues today among many groups.

Shape of the World

Ancient Mesoamericans perceived the world as simultaneously square and round and having three vertical divisions, a setup that was established when the world was created. The square world had four corners and a central point or axis mundi that connected the three vertical layers of the sky, land, and underworld. This square shape likely represents an agricultural field, or milpa.

This square shape of the earth with a fifth central point is best seen in Olmec art, particularly carved greenstone celts that depict four corn plants arranged in a square, and a fifth figure, usually the maize god, in the middle. The San Bartolo Murals in Guatemala depict the creation of the world as the setting up of five trees, each symbolizing one of the world directions. Almost 1,000 years later, an almost identical scene is found in the Dresden Codex, indicating the continuity of this belief.

Colonial period maps show the boundaries of settlements as round, suggesting that they perceived the world as round. In some instances the round world has turtle elements. The idea of the earth as a turtle is common in Maya iconography, especially in relation to the Hero Twins and their father, the Maize god, who is depicted as emerging from the cracked carapace in a famous plate.

Directionality

Depictions of the four-cornered world, particularly in the Fejervary-Mayer and Madrid codices show that each direction had associated attributes tied to it. For example, each direction has a specific type of tree, in which sits a different bird. Colors were also tied to directions, though they were not standardized throughout Mesoamerica. Among the Maya, east is yellow; north is white; west, red; south, black; and the center is green. Specific days were also related to these directions. For example, if today had the quality of east, tomorrow would have the quality of north, two days from now, west, and three days south, returning to the east on the fourth day. The complexity of this time and direction relationship was recorded by the Maya in what is known as the 819-day count.

The Living Landscape

Beginning at least as early as the Formative/Preclassic period, ancient Mesoamericans considered the world around them as alive. The Olmec frequently depicted caves as gaping-mouthed, fanged monsters. The Maya depicted hills as zoomorphic entities. Researchers refer to these depictions as witz monsters. The Azteccontinued with this tradition, as evidenced in the depictions of their emergence place, Chicomoztoc, which frequently is illustrated with a gaping mouth full of fangs. The belief in an animate landscape continues today. For example, the Q’eqchi’ Maya of highland Guatemala believe that the mountains that surround them are living beings who are the guardians of the natural world, and must be properly worshipped. Furthermore, these beings act just like people, holding council meetings, gossiping among themselves, and engaging in acts of violence.

Archaeology: What's Hot Now: Australopithecus sebida

Australopithecus sebida
Sep 15th 2011, 10:00

Australopithecus sebida ("sebida" means fountain or wellspring in seSotho) is a recently discovered hominin (ancient human ancestor). Two well-preserved examples of Au. sebida were recovered from Malapa Cave, a dolomite cave in the Cradle of Humankind archaeological site in Guateng province near Johannesburg, South Africa. Dated using paleomagnetic and Uranium-lead techniques on flowstone and underlying sediments to 1.977 million years ago, Au. sebida is considered by some scholars to be directly ancestral to early modern humans.

Two examples of Au. sebida were recovered from sediments in-filling Malapa Cave. MH1 is a juvenile male, represented by a partial cranium (seen in the image above), a fragmentary mandible and part of the post-cranial skeleton including right leg, right arm and pelvis. Based on comparisons with modern apes and humans, he is estimated to have died at approximately 12-13 years of age. MH 2 is an adult female, represented by isolated maxillary teeth, a partial mandible and partial post-cranial skeletal remains including right leg, right arm and pelvis.

Dates reported in April 2010 placed Au. sebida within a range of 1.78-1.95 million years ago (mya), on the basis of faunal correlation, Uranium-Lead dating and paleomagnetic data. In September of 2011, a scientific team working on the hominin reported a firm date of 1.977 mya, making Au. sebida older than any other known hominid fossil found in Africa to date, including Homo erectus and H. habilis.

Au. sebida has a small body, in comparison to H. erectus, for example, with long upper limbs, large joint surfaces and somewhat primitive limb structures. They were fully bipedal. The two hominins recovered from Malapa Cave are currently classed as Australopithecines, because their brain case is relatively small, and their arms are long for their bodies, in comparison to traditional human ancestors in the Homo group. But scholars researching Au. sebida argue that the evidence from Malapa Cave suggest a reworking of our hominid classifications may be in order.

Archaeology: What's Hot Now: Capacocha Ceremony

Capacocha Ceremony
Sep 14th 2011, 10:01

The capacocha ceremony was an important part of the Inca civilization. The ceremony celebrated key events such as the death of an emperor, the birth of a royal son, a great victory in battle or an annual or biennial event in the Incan calendar. It also was conducted to stop droughts, earthquakes and epidemics.

When a capacocha ceremony was to be held, the Inca sent out to the provinces a demand for tribute payment of gold, silver, shell, cloth, feathers, and llamas and alpacas. They also demanded tribute payment of boys and girls between the ages of 4 and 10, selected for physical perfection.

Capacocha Ceremony Rituals

Capacocha ceremonies lasted several days, including feasting and ritual events. Offerings would be made at many appropriate huacas (shrines), and at the major shrine, a boy and girl were sacrificed and interred together as a couple. The children were reportedly suffocated, killed with a blow to the head or buried alive after ritual inebriation. One capacocha ceremony known from the historic period is Tanta Carhua, a 10 year old girl who was sacrificed to obtain the capac's support for a canal project.

Archaeological evidence for the capacocha ceremony has been identified at about 20 sites in the Andean mountains, and include Cerro El Plomo and Cerro Esmeralda in Chile, Mt. Lullaillaco in Argentina, and Mt. Chachani in Peru.

Otzi the Iceman
Sep 14th 2011, 10:01

Otzi the Iceman is one of those amazing discoveries that continues, even decades after the original find, to surprise us with new bits of information. The glossary entry includes a summary, and you'll find some news stories, a bibliography, and even an extended joke in the Bulwer-Lytton style.

1. Otzi the Iceman (definition)

This entry is a summary of everything known about Otzi that's been published to date: where he was born, where he lived, how tall he was, what he weighed, what he ate, what he did for a living, what his clothes were like, how old he was, and what killed him. We don't know why he was killed--but science suggests that somebody didn't like him very much at all.

2. Moss and the Iceman

Studies of the Iceman's innards revealed a surprising variety of mosses, from different climate regimes suggesting that Otzi was a local man who knew and traveled the Alpine region widely

3. Death of an Iceman

Using multislice computed tomography, a research team from the Swiss Mummy Project at the University of Zurich discovered a 13-mm tear in an artery in the Iceman's chest, and have pinpointed what they think led to the Iceman's death.

4. Otzi's Clothing

A summary and links to detailed news stories about the MALDI-TOF mass spectrometry used to examine Otzi's clothes.

5. Bibliography of Otzi the Iceman

A list of the journal articles and books written about Otzi to date.

6. A Bulwer-Lytton-like Take on the Iceman

T.R. Talbott won a dishonorable mention in the 1997 Bulwer-Lytton Fiction contest (where WWW means "Wretched Writers Welcome"). He (or she, I was never able to contact him or her) took as his/her text the Iceman--and every time I read it I laugh out loud.
