Timing is Everything

Archaeological Dating Table of Contents | Part 2: Chronological Markers and Dendrochronology | Part 3: The Radiocarbon Revolution | Part 4: New Fangled Methods

It is certainly no exaggeration to call the invention of radiocarbon dating a revolution. It finally provided the first common chronometric scale which could be applied across the world. Invented in the latter years of the 1940s by Willard Libby and his students and colleagues James R. Arnold and Ernest C. Anderson, radiocarbon dating was an outgrowth of the Manhattan Project, and was developed at the University of Chicago Metallurgical Laboratory.

Although I am hardly a chemist or a physicist, and so will leave the detailed explanations to those who are better at it than I (for example, Anne Marie Helmenstine's page in About Chemistry), essentially radiocarbon dating uses the amount of carbon 14 available in living creatures as a measuring stick. All living things maintain a content of carbon 14 in equilibrium with that available in the atmosphere, right up to the moment of death. When an organism dies, the amount of C14 available within it begins to decay at a half life rate of 5730 years; i.e., it takes 5730 years for 1/2 of the C14 available in the organism to decay. Comparing the amount of C14 in a dead organism to available levels in the atmosphere, produces an estimate of when that organism died. So, for example, if a tree was used as a support for a structure, the date that tree stopped living (i.e., when it was cut down) can be used to date the building's construction date.

The organisms which can be used in radiocarbon dating include charcoal, wood, marine shell, human or animal bone, antler, peat; in fact, most of what contains carbon during its life cycle can be used, assuming it's preserved in the archaeological record. The farthest back C14 can be used is about 10 half lives, or 57,000 years; the most recent, relatively reliable dates end at the Industrial Revolution, when humankind busied itself messing up the natural quantities of carbon in the atmosphere. Further limitations, such as the prevalence of modern environmental contamination, require that several dates (called a suite) be taken on different associated samples to permit a range of estimated dates.

Calibration

In the 50 or so years since Libby and his associates created the radiocarbon dating technique, refinements and calibrations have both improved the technique and revealed its weaknesses. Calibration of the dates may be completed by looking through tree ring data for a ring exhibiting the same amount of C14 as in a particular sample--thus providing a known date for the sample. Such investigations have identified wiggles in the data curve, such as at the end of the Archaic period in the United States, when atmospheric C14 fluctuated, adding further complexity to calibration.

One of the first modifications to C14 dating came about in the first decade after the Libby-Arnold-Anderson work at Chicago. One limitation of the original C14 dating method is that it measures the current radioactive emissions; Accelerator Mass Spectrometry dating counts the atoms themselves, allowing for sample sizes up to 1000 times smaller than conventional C14 samples.

While neither the first nor the last absolute dating methodology, C14 dating practices were clearly the most revolutionary, and some say helped to usher in a new scientific period to the field of archaeology.

Traveling the Silk Road
Dec 10th 2011, 11:01

The massive network of trails called the Silk Road included 4,600 miles (7,400 kilometers) across deserts and mountains; these roads were largely traveled by one method: camel caravan. Camel caravans were groups of people and camels who traveled in convoys over long distances. In a caravan, people by and large walked alongside camels carrying goods for the markets. Camels were well-suited to the task, which included desert temperatures ranging between 122 and -50 degrees fahrenheit.

Because the substantial cities were situated far apart, people traveling in caravans were supported by caravansaries, roadside inns where water for drinking and ritual bathing was kept, as well as fodder for animals and shops for travelers.

The camel caravan illustrated in this photograph was traveling from Mongolia via the Nankow Pass, and passing through the Great Wall of China, when it was photographed in November, 1902 by C.H. Graves.

Saffron
Dec 9th 2011, 08:22

Saffron is a crazy expensive spice and pigment, that was domesticated around four thousand years ago by the Minoans. Probably.

Used for flavoring, aroma, dyes, and as a painkiller, the screaming yellow stuff today runs something like US$10 a gram--or about US$5000 a pound. The Minoans of ancient Greece may or may not have been people who domesticated saffron, but it was clearly of similar expense and symbolically important to them.

Cattle
Dec 9th 2011, 11:00

There are multiple wild forms of cattle (Bos primigenius), which suggests that the process occurred independently at least twice and perhaps three times. The taurine (humpless, Bos taurus) was probably domesticated somewhere in the Fertile Crescent about 8,000 years ago. Taurine cattle were apparently traded across the planet, and appear in archaeolgoical sites of northeastern Asia (China, Mongolia, Korea) about 5000 years ago.

Evidence for domesticated zebu (humped cattle, Bos indicus)has been discovered at the site of Mehrgahr, in the Indus Valley of Pakistan, about 7,000 years ago. The most controversial is the appearance of cattle in Africa. The earliest non-controversial bones have been found at Capeletti, Algeria, about 6500 BP, but Bos remains are found at African sites in what is now Egypt, such as Nabta Playa and Bir Kiseiba as long ago as 9,000 years, and they may represent domesticated cows.

Archaeology: What's Hot Now: Gobekli Tepe

Gobekli Tepe
Dec 8th 2011, 11:01

The four cultic enclosures excavated so far are similar: they are all circular or oval, they all have twelve T-shaped pillars and two monolithic pillars, they all have a prepared floor. But the animals featured in the reliefs are different, suggesting to Schmidt and colleagues that they may represent people from different settlements who all shared the use of Gobekli Tepe. Certainly, the construction project would have required a sustained labor force to quarry, work and place the stones.

In a 2004 paper, Joris Peters and Klaus Schmidt argued that the animal images might be clues to the location of their makers. Structure A has zoomorphic reliefs dominated by snakes, aurochs, fox, crane and wild sheep: all but the sheep were known as important economically to Syrian sites of Jerf el Ahmar, Tell Mureybet and Tell Cheikh Hassan. Structure B has mostly foxes, which were important to the northern Fertile Crescent, but are also still found throughout the region. Structure C is dominated by wild boar images, suggesting the makers might have come from the central Anti-Taurus to the north, where wild boar are generally found. At Structure D, fox and snake dominate, but there are also crane, aurochs, gazelle, and ass; could this be a reference to water courses along the Euphrates and Tigris rivers?

Eventually, the oval structures at Göbekli Tepe were abandoned and purposely filled-in with refuse, and a new set of rectangular enclosures were built, not as well made, and with smaller pillars. It's interesting to speculate about what might have occurred to cause that.

One thing to remember about Göbekli Tepe's architecture is that it was constructed by hunter-gatherers, ancestors by a few generations of the people who would invent farming. Several of their residential settlements have been discovered along the Euphrates river not far from Gobekli. Food remains from Göbekli and other sites in the vicinity suggest they ate pistachios, almonds, peas, wild barley, wild einkorn wheat and lentils; and fox, asiatic wild ass, wild boar, aurochs, goitered gazelle, wild sheep, and Cape hare. The descendants of the makers of Göbekli would domesticate many of these animals and plants.

Göbekli's importance is as the earliest human-built cult structures in the world, and I'm eagerly waiting to see what the next decades of research shows us.

Archaeology: What's Hot Now: Wine and its Origins

Wine and its Origins
Dec 8th 2011, 11:01

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.

Montanissell Cave (Spain)
Dec 8th 2011, 11:01

Montanissell Cave is a natural hidden karst cave located deep within the south face of Montanissell Mountain in the Catalan Pre-Pyrenees mountains. Montanissell's interior gallery served as a family burial chamber during the Middle Bronze Age. Discovered in 2004 by a team of amateur cavers, the site was investigated in 2005 by the University of Lleida with the support of the Museu d’Arqueologia de Catalunya.

The burial chamber lies deep within the cave, through a narrow 40 meters (130 feet) long passageway and descending into a pit some 28 m (92 ft) deep. At the bottom of the pit is vast gallery, a restricted corner of which was used as a burial space, set off from the remainder of the gallery by roof fall blocks. The skeletons were placed in a flexed position directly on the ground, and they were apparently not covered with earth, although a thin layer of calcite covers the remains closest to the cave wall. The difficulty of access to the graves is in marked contrast to other Catalan Bronze Age burials, which are often marked with dolmens or placed in collective burials in shallow caves, all with easy access.

Burials in Montanissell Cave

The eight individuals found in the cave are three adults (one male, two female) and five juveniles (three girls, one boy and one undetermined sex). Grave goods within the cave include two bronze spiral bracelets, a necklace of animal teeth and brass beads. Bones from four sheep/goats and fragments from four pottery vessels were also discovered near the human remains.

A bronze strip measuring 60 cm long by 4 cm wide was found placed in the middle of the chamber. One end of the plate was an embossed geometric design; it is interpreted as a diadem or decorative headband. Similar objects have been recovered from southern France, all dated to the Middle Bronze Age and associated with the Rhone and Polada cultures, with contacts with the Unetice culture. This object is also connected to the Blechkreis bronze metallurgy of eastern France, western Switzerland and northern Italy.

Superposition of the bones indicated to researchers that the burials were not simultaneous but occurred over a short period of time (not more than 100 years); radiocarbon dating of the bones clearly places the burials ~3200 BP. Osteoarthritis was identified in the two oldest individuals (both aged 30-45) The evidence of similar burial goods and locations suggests that the burials represented members of a nuclear family, however, ancient DNA studies indicate that the adult women could not be the mothers of any of the non-adults. The adult male and three of the younger people appear to be related; but the others are not. Further, the individuals in Montanissell Cave have a wide diversity of mtDNA haplogroups.

Nuclear Families in the Bronze Age

Despite the limited genetic relationship between the individuals buried at the site, researchers are inclined to argue that Montanissell Cave represents the burial place of a small group with a patrilocal mating system (i.e., the women had to be integrated into the group from elsewhere); or the pattern is a nuclear family, made up in part of people who are not necessarily biologically related to one another.

Aztec Xaltocan
Dec 7th 2011, 08:18

Xaltocan is an archaeological site that, like the Aztec capital of Tenochtitlan, was once located on a man made island floating within the Basin of Mexico: the lakes of the basin were drained after the Spanish colonization.

Xaltocan's importance as an archaeological site rests on its history: having been both a thriving independent polity and a subject community to the Aztec state, Xaltocan can tell us much about the economic and social changes brought about by integration into the Aztec empire.

Royal Road
Dec 7th 2011, 11:01

The Royal Road was a major intercontinental thoroughfare built by the Achaemenid king Darius the Great (521-485 BC), to allow access to their conquered cities. It is also the road that Alexander the Great used to conquer the Achaemenid dynasty.

The Royal Road led from the Aegean Sea to Iran, a length of some 1500 miles. A major branch connected the cities of Susa, Kirkuk, Nineveh, Edessa, Hattusa and Sardis. The journey from Susa to Sardis was reported to have taken 90 days on foot, and three more to get to the Mediterranean coast at Ephesus.

Architectural Features of the Royal Road

Intact sections of the road, such as that at Gordion and Sardis, are cobble pavements atop a low embankment from 5-7 meters in width and, in places, faced with a curbing of dressed stone.

A hundred and eleven way-posting stations were reported to existing on the road, where fresh horses were to be had. A handful of way stations have been tentatively identified archaeologically. One possibility is a large (40x30 meters) five-room stone building near the site of Kuh-e Qale; another is at the site of JinJan (Tappeh Survan), in Iran.

Archaeology of the Royal Road

Archaeological evidence suggests that there was a precursor to the Royal Road, that part connecting Gordion to the coast probably used by Cyrus during his conquest of Anatolia. It is possible that the first roads were established in the 10th century BC under the Hittites. These roads would have been used as trade routes by the Assyrians and Hittites at Boghakzoy.

Levallois Technique
Dec 7th 2011, 11:01

Definition:

Levallois is the name archaeologists have given to a distinctive flint knapping technique, which makes up part of the ancient Acheulean and Mousterian artifact assemblages.

The stone tool making technique involves flaking pieces off the edge of a large piece of flint until it is shaped like a turtle shell, and using the core to make tools. The Levallois technique is thought to have been used by Neanderthals in Europe beginning about 250,000 years ago, and then perfected during the Mousterian of 100,000 years ago.

Definition:

Post-Processual Archaeology is, more than anything else, a critique of processual archaeology.

Archaeology at its best is a study sturdily balanced between anthropology (as the study of human cultures), history (as the study of human historical and prehistoric past), and archaeometry (as the science of decay). Leaning too hard in any one direction pulls the balance out too far (even though it is asking a bit much for one scholar to be all three things). Post-processualists such as Ian Hodder criticized the processualists as getting too involved with the archaeometry of it all and ignoring the stuff of man--the behavior, the gender, the culture of people. Naturally, the processualists think the post-processualists go too far.

There's a surprisingly good article on post-processual archaeology written by anonymous members of the public on the Wikipedia site. A brief bibliography of articles discussing post-processualism was created for this project.

Mammoths
Dec 7th 2011, 11:01

Definition:

Mammoths (Mammuthus primogenus) were a species of ancient extinct elephant. Mammoth adults were about 10 feet tall at the shoulder, with long tusks and a coat of long reddish or yellowish hair--which is why you'll sometimes see them described as woolly mammoths. They roamed Northern Europe and, eventually, North America.

Mastodons (Mammut americanum) were also ancient, enormous elephants, slightly smaller (6-10 feet tall), no hair, and restricted to the North America continent. Both of these megafauna died out at the end of the Ice Age, about 10,000 years ago, as part of the great megafaunal extinction. They were hunted by people, and various archaeological sites have been found around the world where the animals were killed and/or butchered. Mammoths and mastodons were exploited for meat, hide, bones, and sinew for food and other purposes, including house construction.

Top 10 Things to Know about the Aztecs
Dec 6th 2011, 17:00

Whether you are a student, a Mexico’s aficionado, a tourist, or simply moved by curiosity, here there is an essential guide to what you may want to know about Aztec civilization

1. Who were the Aztecs?

The Aztecs, who should be more properly called Mexica, are one of the most important and famous civilizations of Mesoamerica. In the Postclassic period they reached Central Mexico and established their capital there. In few centuries they managed to control almost all Mexico through an extended empire.

2. Where did they live?

The Aztec/Mexica were not native of Central Mexico but migrated from north, from a mythical land called Aztlan. Historically, they were the last of many Nahuatl speaking tribes, generally called Chichimeca, who migrated towards south from what is now Northern Mexico or the Southwest of the United States due to a period of great drought. After almost two centuries of migration, at around A.D. 1250, the Mexica arrived in the Valley of Mexico, and established themselves on the shore of lake Texcoco.

3. Mexico-Tenochtitlan, the Aztec Capital

Nicoletta Maestri

Mexico-Tenochtitlan is the name of the Aztec capital. The city was founded in AD 1325. The place was chosen following an omen of the god Huitzilopochtli, who commanded his people to settle where they would have found an eagle perching on a cactus and devouring a snake. The place was very discouraging: a swampy area around the lakes of the Valley of Mexico. Tenochtitlan grew rapidly thanks to its strategic position and the Mexica military skills. When the European arrived, Tenochtitlan was one of the largest and better organized cities of the world.

4. Origin of the Aztec Empire

Thanks to their military skills and strategic position, the Mexica became allies of the most powerful cities of the Valley, Azcapotzalco, and obtained tributes from these military campaigns. They then obtained recognition as a kingdom, electing as their first ruler Acamapichtli, a member of the royal family of Culhuacan, a powerful city-state in the Basin of Mexico. Finally, in 1428, they allied themselves with the cities of Texcoco and Tlacopan, forming the Triple Alliance. This event starts the Mexica expansion in the Basin of Mexico and beyond, and the birth of the empire.

5. Aztec Economy

Aztec economy was based on three things: market exchange, tribute payment and agricultural production. The famous Aztec market system included both local and long-distance trade. Markets were held on a regular basis and a high degree of specialization existed. The most important market was that of Tlatelolco, sister city of Mexico-Tenochtitlan. Tribute collection was among the main reasons for the Aztecs to conquest a region. Tributes paid to the empire usually include goods or services, depending on the distance and status of the tributary city. In the Valley of Mexico, the Aztecs developed sophisticated agricultural systems which include: irrigation systems, floating fields, called chinampas, and hillside terrace systems

6. Aztec Society

Aztec society was highly stratified. The population was divided into nobles, pipiltin, and the commoners, macehualtin. The nobles were exempted from taxes and covered government position, whereas the commoners paid tributes in form of taxes and labor. These people were grouped into sorts of clan, called calpulli. At the bottom of Aztec society there were the slaves. These were criminals, people who couldn’t pay taxes, and prisoners. At the top of Aztec society stood the ruler, or Tlatoani, of each city-state, and his family. The supreme king, or Huey Tlatoani, was the emperor, and king of Tenochtitlan. The second most important political position of the empire was that of the cihuacoatl, a sort of viceroy or prime minister. The position of emperor was not hereditary, but elective. He was chosen by a council of nobles.

7. Aztec Politics

The basic political unit for the Aztecs and in the Basin of Mexico in general, was the city-state, or altepetl. Each altepetl was a kingdom, ruled by a tlatoani. Each altepetl controlled a surrounding rural area that fed the community. Warfare and marriage alliances were the mean through which Aztec politics expanded. An intense net of informants and spies helped the Mexica government to maintain control over a large empire and intervene rapidly in case of uprising.

8. Aztec Warfare

Warfare was the mean to obtain tributes and captives for sacrifices. The Aztec didn’t have a standing army but soldiers were drafted among the macehualtin. In theory, a military career and the access to higher military orders, such as the one of the eagle and jaguar, were open to everybody who distinguished himself in battle. However, in reality, these high ranks were often reached only by noblemen. War actions included battles against neighbour groups, flower wars - aimed to obtain captives - and coronation wars. Type of weapons included both offensive and defensive tools, such as spears, bows and arrows, swords, clubs, as well as shields, armories, and helmets. Weapons were made out of stones, wood and obsidian, but not metal.

9. Aztec Religion

Nicoletta Maestri

As other Mesoamerican cultures, the Aztec/Mexica worshipped many gods who represented the different forces and manifestations of nature. The term used by the Aztec to define the idea of a deity or a supernatural power is teotl, which is often part of a god name. The Aztecs divided their gods into three groups which supervised different aspect of the world: the sky and celestial beings, the rain and agriculture, and the war and sacrifices.

10. Aztec Art and Architecture

Nicoletta Maestri

The Mexica had skilled artisans, artists and architects. When the Spaniards arrived, they were surprised by these people architectural accomplishments. Raised, paved roads connected Tenochtitlan to the mainland; bridges, dikes and aqueducts regulated water level and flow in the lakes, allowed to separate fresh from salt water, and provide fresh, drinkable water to the city. Administrative and religious buildings were brightly colored and decorated with stone sculptures. Aztec art is best known for its example of monumental stone sculptures, some of which of impressive size. Other arts in which the Aztec excelled are feather and textile works, ceramic production, wooden art, obsidian and lapidary works. Metallurgy, by contrast, was in its infancy among the Mexica when the European arrived. However, metal products were imported through trade and conquest. Metallurgy in Mesoamerica probably arrived from South America and people of Western Mexico, among whom the Tarascans, mastered its techniques.

11. The Aztecs and the Spanish Conquest

The Conquest of Mexico and the subjugation of the Aztecs, although completed in few years, was a complicated process which involved many actors. When Hernan Cortes reached Mexico in 1519 he and his soldiers found important allies among the local communities subjugated by the Aztecs, for example the Tlaxcalans, who saw in the newcomers a way to free themselves from the Aztecs. The introduction of germs and diseases, which preceeded the actual invasion, decimated the native population, and therefore facilitated the control over the new land. Entire communities were forced to abandon their homes and new villages were created and controlled by Spanish nobility. A least formally, local leaders were left in place but they had no real powers. Christianization proceeded through the destruction of pre-Hispanic temples, idols and books by Spanish friars, but at the same time these religious orders collected, in the so called codices, an incredible amount of information about Aztec culture, practices and beliefs.

Archaeology: What's Hot Now: Peer Review

Peer Review
Dec 6th 2011, 17:00

Peer review, at least in intent, is the way the editors of academic journals attempt to keep the quality of articles in their publications high, and assure that poor or fallacious research does not get published. The process is tied up with political and economic issues involving tenure and pay scales, in that an academic who participates in the peer review process (whether as author, editor, or reviewer) gets rewarded for that participation in an increase in reputation which can lead to an increase in pay scales, rather than direct payment for services rendered.

In other words, none of the people involved in the review process is paid by the journal in question, with the sole exception (maybe) of one or more editorial assistants. The author, editor, and reviewers all do this for the prestige involved in the process; they are generally paid by the university or business that employs them, and in many cases, that pay is contingent upon obtaining publication in peer-reviewed journals. The editorial assistance is generally provided in part by the editor's university and in part by the journal.

The Review Process

The way academic peer review works (at least in the social sciences), is that a scholar writes an article and submits it to a journal for review. The editor reads it over and finds between three and seven other scholars to review it.

The reviewers selected to read and comment on the scholar's article are chosen by the editor based on their reputations in the specific field of the article, or whether they are mentioned in the bibliography, or if they are personally known to the editor. Sometimes the author of a manuscript suggests some reviewers. Once a list of reviewers is drawn up, the editor removes the name of the author from the manuscript and forwards a copy to the chosen stout hearts. Then time passes, a lot of time, generally, between two weeks and several months.

When the reviewers have all returned their comments (made directly on the manuscript or in a separate document), the editor makes a preliminary decision about the manuscript. Is it to be accepted as is? (This is very rare.) Is it to be accepted with modifications? (This is typical.) Is it to be rejected? (This last cases is also fairly rare, depending on the journal.) The editor strips out the identity of the reviewers and sends along the comments and her preliminary decision about the manuscript to the author.

If the manuscript was accepted with modifications, it is then up to the author to make changes until the editor is satisfied that the reviewers' reservations are met. Eventually, after several rounds of back and forth, the manuscript is published. The period from submission of a manuscript to publication in an academic journal generally takes anywhere from six months to over a year.

Problems with Peer Review

Problems inherent in the system include the time sink between submission and publication, and the difficulty obtaining reviewers who have the time and inclination to give thoughtful, constructive reviews. Petty jealousies and full blown political differences of opinion are difficult to restrain in a process where no one is made accountable for a specific set of comments on a particular manuscript, and where the author has no ability to correspond directly with her reviewers. However, it must be said that many argue that the anonymity of the blind review process allows a reviewer to freely state what he or she believes about a particular paper without fear of reprisal.

Recent Findings

The journal Behavioral Ecology changed its peer review system from one which identified the author to reviewers (but reviewers remained anonymous) to a completely blind one, in which both author and reviewers are anonymous to one another. In a forthcoming paper, Amber Budden and colleagues report that statistics comparing the articles accepted for publication before and after the watershed year (2001) indicated that significantly more women have been published in BE since the double-blind process began. Similar ecological journals using single-blind reviews over the same period do not indicate a similar growth in the number of woman-authored articles, leading researchers to believe that the process of double-blind review might assist with the 'glass ceiling' effect.
