Wine and its Origins
Aug 8th 2011, 10:00

Wine is an alcoholic beverage made from grapes; and depending on your definition of "made from grapes" there are at least two independent inventions of the lovely stuff. The oldest known possible evidence for the use of grapes as part of a wine recipe with fermented rice and honey was in China, about 9,000 years ago. Two thousand years later, the seeds (or I suppose pips) of what became the European wine-making tradition began in western Asia.

Archaeological Evidence

Archaeological evidence of wine-making is a little difficult to come by, of course; the presence of grape seeds, fruit skins, stems and/or stalks in an archaeological site does not necessarily imply the production of wine. Two main methods of identifying wine making that are accepted by scholars are identifying domesticated stocks, and discovering grape processing evidence.

The main change incurred during the domestication process of grapes is that the domesticated forms have hermaphrodite flowers. What that means is that the domesticate forms of the grape are able to self-pollinate. Thus, the vintner can pick traits she likes and, as long as she keeps them all on the same hillside, she need not worry about cross-pollination gumming up the works.

The discovery of parts of the plant outside its native territory is also accepted evidence of domestication. The wild ancestor of the European wild grape (Vitis vinifera va. sylvestris) is native to western Eurasia between the Mediterranean and Caspian seas; thus, the presence of V. vinifera outside of its normal range is also considered evidence of domestication.

Chinese Wines

But the story really must start in China. Residues on pottery sherds from the Chinese early Neolithic site of Jiahu have been recognized as coming from a fermented beverage made of a mixture of rice, honey and fruit, radiocarbon dated to ~7000-6600 BC. The presence of fruit was identified by the tartaric acid/tartrate remnants in the bottom of a jar, familiar to anyone who drinks wine from corked bottles today. Researchers could not narrow the species of the tartrate down between grape, hawthorn, or longyan or cornelian cherry, or a combination of two or more of those. Grape seeds and hawthorn seeds have both been found at Jiahu. Textual evidence for the use of grapes (but not grape wine) date to the Zhou Dynasty (ca 1046-221 BC).

If grapes were used in wine recipes, they were from a wild grape species native to China-there are between 40 and 50 different wild grape species in China-not imported from western Asia. The European grape was introduced into China in the second century BC, with other imports resulting from the Silk Road.

Western Asia Wines

The earliest firm evidence for wine-making to date in western Asia is from the Neolithic period site called Hajji Firuz, Iran, where a deposit of sediment preserved in the bottom of an amphora proved to be a mix of tannin and tartrate crystals. The site deposits included five more jars like the one with the tannin/tartrate sediment, each with a capacity of about 9 liters of liquid. Hajji Firuz has been dated to 5400-5000 BC.

Sites outside of the normal range for grapes with early evidence for grapes and grape processing in western Asia include Lake Zeriber, Iran, where grape pollen was found in a soil core just before ~4300 cal BC. Charred fruit skin fragments were found at Kurban Höyük in southeastern Turkey by the late 6th-early 5th millennia BC.

Wine importation from western Asia has been identified in the earliest days of dynastic Egypt. A tomb belonging to the Scorpion King (dated about 3150 BC) contained 700 jars believed to have been made and filled with wine in the Levant and shipped to Egypt.

European Wine Making

In Europe, wild grape (Vitis vinifera) pips have been found in fairly ancient contexts, such as Franchthi Cave, Greece (12,000 years ago), and Balma de l'Abeurador, France (about 10,000 years ago).

Excavations at a site in Greece called Dikili Tash have revealed grape pips and empty skins, direct-dated to between 4400-4000 BC, the earliest example to date in the Aegean.

A wine production installation dated to ca. 4000 cal BC has been identified at the site of Areni 1 in Armenia, consisting of a platform for crushing grapes, a method of moving the crushed liquid into storage jars and (potentially) evidence for the fermentation of red wine.

Human Migration
Aug 8th 2011, 10:00

Someplace in Africaâ€"probably in East Africa near the Rift Valleyâ€"modern humans evolved about 200,000 years ago. The population rose and fell, and for one reason or anotherâ€"perhaps climate changes, perhaps population pressure, perhaps wanderlustâ€"small subsets of the people left to go elsewhere, creating their own groupsâ€"or rather our own groups, for these are, after all, our ancestors. Those groups spread in the same way, small subsets of the original groups leaving for greener pastures, sometimes returning and rejoining, sometimes leaving again. Africa has a huge range of environmentsâ€"deserts, coastal regions, pampas, rivers, lakes, and mountains, and it is certain that some of these required human adaptationsâ€"behavioral, cultural and physicalâ€"to the demands of the various climates.

Eventually, we left Africa, somewhere between 50,000â€"100,000 years ago. Tishkoff and colleagues believe that the main exit path way was out of east Africa, in the Red Sea area.

Archaeology: What's Hot Now: Asmar Sculpture Hoard (Iraq)

Asmar Sculpture Hoard (Iraq)
Aug 7th 2011, 10:00

Definition:

The Tell Asmar sculpture hoard is a collection of 12 human effigy statues, discovered at the Mesopotamian site of Tell Asmar. The hoard was discovered during Henri Frankfort's Oriental Institute excavations in the 1930s. They were stacked in several layers within an 85x50 cm hole 1.25 meters (about 4 feet) below the floor of the structure known as the Square Temple.

The statues average about 42 centimeters in height. They are of men and women with large staring eyes, upturned faces, and clasped hands, dressed in the skirts of the Early Dynastic period of Mesopotamia. They are believed to represent gods and goddesses and their worshipers. The largest male figure is thought to represent the god Abu, based on symbols carved into the base.

The Asmar statues were modeled from processed gypsum (calcium sulphate). The ancient technique involves firing gypsum at about 300 degrees Fahrenheit until it becomes a fine white powder (called plaster of Paris). The powder is then mixed with water and then modeled and/or sculpted.

The exact location of the hoard with regard to the temples is somewhat in question. Most sources refer to it as either below the Abu or Square temples at Asmar. Evans (cited below) believes the hoard, discovered well beneath the floors of the Square Temple, predates both temples.

Sources

The Metropolitan Museum's exhibit sculpture of the Early Dynastic period has a large image of one of the Asmar statues, on its website. Evans's article has an image of the complete hoard.

Archaeology: What's Hot Now: History of Clovis

History of Clovis
Aug 7th 2011, 10:00

Clovis is the name archaeologists have given to the earliest well-established human culture in the North American continent. Clovis were the first big game hunters of the Paleoindian tradition, although they were probably not the first people in the American continents. The first people are tentatively called Pre-Clovis, I suppose for lack of a better terminology.

Clovis archaeological sites are dated between 11,000-10,800 RCYBP (which converts to circa 12,500-12,900 calendar years before the present) and they are found pretty much throughout North America. The point and culture are named after the town in New Mexico near where it was first identified, although the name of type site is officially Blackwater Draw Locality 1.

Clovis Life Styles

The Clovis people were primarily, but not exclusively of course, big game hunters of megafauna, now extinct forms of large bodied animals like mammoth, bison, horse and camel, hunted using a highly mobile hunting strategy.

Environmental conditions at the time were dry, and it might be speculated that the Americans took up big game hunting (from the mixed hunter-gatherer-fisher strategy of pre-clovis) as an adaptation to drought. But, for whatever reason the people started hunting elephants and horses and bison, the big-game hunting strategy only lasted as long as there were big game to hunt.

The End of Clovis

The end of the big game hunting strategy used by Clovis appears to have occurred very abruptly, sometime about 9,800 to 10,800 RCYBP. The reasons for the end of big game hunting is, of course, the end of big game: most of the megafauna disappeared about the same time.

Scholars are divided about why the big fauna disappeared, although currently they are leaning towards a natural disaster combined with climate change that killed off all the large animals. It's possible that the extinction was helped along by over-kills. Overkills are known from buffalo jumps at the Murray Springs and Head-Smashed-In sites, among others. A buffalo jump is when a herd of buffaloes are purposefully stampeded off a cliff; the hunters then butcher a few of the animals and leave the rest, usually with quite a bit of waste. But, there aren't that many buffalo jumps and no elephant jumps, so, that kind of evidence is not strongly compelling.

One recent discussion of the natural disaster theory concerns the identification of a black mat marking the end of Clovis sites. This theory hypothesizes that an asteroid landed on the glacier that was covering Canada at the time and exploded causing fires to erupt all over the dry North American continent. An organic "black mat" is in evidence at many Clovis sites, which is interpreted by some scholars as ominous evidence of the disaster. Above the black mat are no more "clovis" sites.

Clovis Sites

Despite the brevity of the culture (between 300-500 years), Clovis sites are found throughout the United States, northern Mexico and southern Canada. Very few large Clovis sites are known--the largest is the Gault site in Texas.

An equivalent big-game hunting lifestyle in South America is characterized by Fishtail Points.

Archaeology: What's Hot Now: Lascaux Cave

Lascaux Cave
Aug 7th 2011, 10:00

Lascaux Cave is a rockshelter in the Dordogne Valley of France with fabulous cave paintings, painted between 15,000 and 17,000 years ago. Although it is no longer open to the public, a victim of too much tourism and the encroachment of dangerous bacteria, Lascaux has been recreated, online and in replica format, so that visitors may still see the amazing paintings of the Upper Paleolithic artists.

Lascaux's Discovery

During the early fall of 1940, four teenage boys were exploring the hills above the Vézère River near the town of Montignac in the Dordogne Valley of south central France when they stumbled on an amazing archaeological discovery. A large pine tree had fallen from the hill years before and left a hole; the intrepid group slipped into the hole and fell into what is now called the Hall of the Bulls, a 20 by 5 meter (66 x 16 foot) tall fresco of cattle and deer and aurochs and horses, painted in masterful strokes and gorgeous colors some 15,000-17,000 years ago.

Lascaux Cave Art

Lascaux Cave is one of the world's great treasures. Exploration of its vast interior revealed about six hundred paintings and almost 1,500 engravings. Subject matter of the cave paintings and engravings reflect the climate of the time of their painting. Unlike older caves which contain mammoths and woolly rhinoceros, the paintings in Lascaux are birds and bison and deer and aurochs and horses, all from the warming Interstadial period. The cave also features hundreds of "signs", quadrilateral shapes and dots and other patterns we'll surely never decipher. Colors in the cave are blacks and yellows, reds and whites, and were produced from charcoal and manganese and ocher and iron oxides, which were probably recovered locally and do not appear to have been heated prior to their use.

Restorations at Lascaux Cave

Sadly, or perhaps inevitably, the beauty of Lascaux drew tremendous numbers of tourists by the late 1950s, and the size of the traffic endangered the paintings. The cave was closed to the public in 1963. In 1983, a replica of the Hall of the Bulls was opened, and it is there that most tourists go.

The original paintings have been restored, and we are tremendously fortunate that one of the first websites on the Internet was the Lascaux Cave siteâ€"in fact, it was the first web site I ever saw, back in 1994 or so. Today it is a marvel of wonderful graphics-enhanced information, truly one of my favorite web sites. Loads of pictures from each of the rooms; pictures of the boys as they are today and history and archaeological information as well. The discussion of the deterioration of Lascaux in 1963 and what the French government did to create a replica is particularly interesting. A time line illustrates Lascaux's place in time within the collection of known Paleolithic cave art sites, and active links on the line take you to Cosquer, Chauvet, La Ferassie, Cap Blanc and other caves in the Dordogne valley.

In 2009, the French government opened a new webpage for Lascaux. It features a video walk through of the cave, so you really get a feel for the warm, womb-like cave. A haunting sound track and extremely detailed views of each of the large panels are also available. It is even more spectacular than the original, and that's saying quite a bit.

Recent Research at Lascaux

Recent research on Lascaux has included some investigations of the hundreds of bacteria which have formed in the cave. Because it was air conditioned for decades, and then treated biochemically to reduce mold, many pathogens have made a home in the cave, including the bacillus for Legionnaire's disease. It is unlikely that the cave will ever be opened to the public again.

Lascaux's web sites are fully realized in French, Spanish, German, and English, and a real treat to visit. The website is a true innovation on the part of the French government, both conserving one of the world's most treasured art galleries and permitting untold numbers of visitors to see it. Even if we can never get into Lascaux Cave, there's two wonderful web sites to let us get a taste of the work of the masters of Paleolithic cave art.

Careers in Archaeology Data...
Aug 7th 2011, 10:00

From time to time, I get email from people asking about career paths in archaeology. Some of them are middle and high school students who want to know what courses they should take. Some of them are college students, wondering what the real career options are in archaeology--how much do jobs pay, how easy is it to get those jobs. And some of them are adults, from varied backgrounds--biology, education, library science, chemistry, writing--and they want to know how they might change careers, and want to know if their backgrounds will be useful.

It's impossible to give a simple answer to any one of my correspondents. Because archaeology is the study of past human behavior, it is one of those sciences that uses every other science--and a lot of studies that are not science. And so, any and all courses may be useful to a career as an archaeologist. Think about it; geography, math, biology, computer science, sure. Gardening? Yep, you learn about soils and cultivation practices, that's useful. Theatrical scene design? You bet, helps with drawing plan maps and understanding ancient theaters. Basket-weaving? Absolutely, fabrics and textiles are an important study in archaeology.

Job opportunities and pay vary depending on location and what skills and background you have. If you want to be a working archaeologist in a cultural resources firm, there are plenty of jobs, and the pay is reasonable; get a master's degree in anthropology/archaeology with experience, and you're set. If you want to be a college professor, the pay is still reasonable, but the jobs are few and far between and people stay in them for a very very long time; for that you'll need a PhD from a great institution and a lot of luck.

And in many, if not most cases, choosing archaeology as a second career is a workable option. A whole slew of specialists work in archaeology--people who concentrate on animal bone, people who work with geographic information systems, people who write and produce videos for the public, people who make public policy.

What you need is a list and description of kinds of jobs that are available in the field, what the jobs entail, what kind of background you need, where are they based, what kind of money they pay. So, starting today, I'm building a database of exactly that sort of information. The Careers in Archaeology Database is just getting started, and I'll continue to add to it over the winter.

Any suggestions? Write me...

Archaeology: What's Hot Now: Hominin

Hominin
Aug 6th 2011, 10:00

Definition:

Over the last few years, the word "hominin" has crept into the public news stories about our human ancestors. This is not a misspelling for hominid; this reflects an evolutionary change in the understanding of what it means to be human.

Up until the 1980s, paleoanthropologists generally followed the taxonomic system followed by the 18th century scientist Carl Linnaeus, when they spoke of the various species of humans. The family of Hominoids included the subfamily of Hominids (humans and their ancestors) and Anthropoids (chimps, gorillas, and orangutans). The problem is, recent molecular studies show that humans, chimps and gorillas are closer to one another than orangutans. So, scientists split the Hominoids into two subfamilies: Ponginae (orangutans) and Homininae (humans and their ancestors, and chimps and gorillas). But, we still need a way to discuss humans and their ancestors as a separate group, so researchers have proposed a further breakdown of the Homininae subfamily, to include Hominini (humans and their ancestors), Panini (chimps), and Gorillini (gorillas).

So, roughly speaking, a Hominin is what we used to call a Hominid; a creature that paleoanthropologists have agreed is human or a human ancestor. These include all of the Homo species (Homo sapiens, H. ergaster, H. rudolfensis), all of the Australopithecines (Australopithicus africanus, A. boisei, etc.) and other ancient forms like Paranthropus and Ardipithecus.
