Minoan Linear A, Linear B, Knossos & Mycenae

Linear B tablet HT 118 (Haghia Triada), livestock on plots of land:

Minoan Linear A tablet HT 118 Haghia TriadaWhile this tablet does present some problems in the decipherment of the kinds of livestock on it, that does not mean we do not have a relatively reasonable picture of which ones they are. Beside madi, which appears to mean “pig” from the context, the other 3 are qaqaru, arisa and riruma. Now these 3 probably mean “cow”, “bull” and “ox” in turn. But if they must be permuted. In other words, if the first word, qaqaru, means “cow”, then the other two mean “bull” and “ox”, but in which order we cannot tell. Thus, it is necessary to permute all 3 words for all 3 kinds of livestock at each occurrence. The supersyllabogram KI almost certainly refers to “a plot of land”, because it is repeated twice, and after all, we do find…

Studying dental plaque from a 1.2 million year old hominin (early human species), recovered by the Atapuerca Research Team in 2007 in Sima del Elefante in northern Spain, archaeologists extracted microfossils to find the earliest direct evidence of food eaten by early humans.
These microfossils included traces of raw animal tissue, uncooked starch granules indicating consumption of grasses, pollen grains from a species of pine, insect fragments and a possible fragment of a toothpick.
All detected fibres were uncharred, and there was also no evidence showing inhalation of microcharcoal – normally a clear indicator of proximity to fire.
The timing of the earliest use of fire for cooking is hotly contested, with some researchers arguing habitual use started around 1.8 million years ago while others suggest it was as late as 300,000-400,000 years ago.
Possible evidence for fire has been found at some very early sites in Africa. However, the lack of evidence for fire at Sima del Elefante suggests that this knowledge was not carried with the earliest humans when they left Africa.
The earliest definitive evidence in Europe for use of fire is 800,000 years ago at the Spanish site of Cueva Negra, and at Gesher Benot Ya’aqov, Israel, a short time later.
Taken together, this evidence suggests the development of fire technology occurred at some point between 800,000 and 1.2 million years ago, revealing a new timeline for when the earliest humans started to cook food.
Dr Karen Hardy, lead author and Honorary Research Associate at the University of York and ICREA Research Professor at the Universitat Autònoma de Barcelona, said: “Obtaining evidence for any aspect of hominin life at this extremely early date is very challenging. Here, we have been able to demonstrate that these earliest Europeans understood and exploited their forested environment to obtain a balanced diet 1.2 million years ago, by eating a range of different foods and combining starchy plant food with meat.
“This new timeline has significant implications in helping us to understand this period of human evolution — cooked food provides greater energy, and cooking may be linked to the rapid increases in brain size that occurred from 800,000 years ago onwards.
“It also correlates well with previous research hypothesising that the timing of cooking is linked to the development of salivary amylase, needed to process cooked starchy food. Starchy food was an essential element in facilitating brain development, and contrary to popular belief about the ‘Paleodiet’, the role of starchy food in the Palaeolithic diet was significant.”
Dr Anita Radini, PhD student at the University of York said: “These results are very exciting, as they highlight the potential of dental calculus to store dietary and environmental information from deep in the human evolutionary past. It is also interesting to see that pollen remains are preserved often in better conditions than in the soil of the same age. Overall this is a very positive step in the discipline, in terms of preservation of material in the calculus matrix.”

14,000-year-old faba seeds contain clues to the timing of the plants’ domestication

Like all food crops, the faba, or fava, bean — a nutritious part of many the diet of many cultures diets — had a wild ancestor. Wild faba is presumed to be extinct, but Weizmann Institute of Science researchers have now identified 14,000-year-old remains of seeds that offer important clues as to the time and place that this plant grew naturally. Understanding the ecology of the wild plants’ environment and the evolution they underwent in the course of domestication is crucial to improving the biodiversity of the modern crop. The findings were reported in Scientific Reports.

Dr. Elisabetta Boaretto, head of the “Timing of Cultural Changes” track of the Max Planck-Weizmann Center for Integrative Archaeology and Anthropology, and Dr. Valentina Caracuta, a former postdoctoral fellow in Boaretto’s group who is currently a researcher at the University of Salento-Italy, had previously shown that the 10,200-year-old faba beans discovered in three archaeological sites in Lower Galilee were the earliest faba bean ever domesticated.

The new finding — faba seeds from an archaeological site, el-Wad, on Mount Carmel in Northern Israel — came from the earliest levels of an excavation that had been carried out by Profs. Mina Evron and Daniel Kaufman, and Dr. Reuven Yeshurun, all of Haifa University. The people living at that time, the Natufians, were hunter-gathers, and thus the plants there were growing wild. Boaretto and Caracuta performed radiocarbon dating and micro X-ray CT analysis on the preserved pieces of bean to pinpoint their age and identify them as the ancestors of the modern fava bean.

“Sometime between 11,000 and 14,000 years ago, people in this region domesticated faba — around the same time that others farther north were domesticating wheat and barley,” says Boaretto. Faba, a nutritious legume, is eaten around the world; in some places it is used for animal feed; and it fixes nitrogen in the soil. “Understanding how this plant was adapted to the habitat of the Carmel 14,000 years ago can help us understand how to create new modern varieties that will better be able to withstand pests and tolerate environmental stress,” she says.

This research is supported by by the Max Planck-Weizmann Center for Integrative Archaeology and Anthropology “Timing of Cultural Changes”; and the Exilarch Foundation for the Dangoor Research Accelerator Mass Spectrometer. The faba bean sample was dated at the Dangoor Research Accelerator Mass Spectrometer D-REAMS, Weizmann Institute of Science.

The Weizmann Institute of Science in Rehovot, Israel, is one of the world’s top-ranking multidisciplinary research institutions. Noted for its wide-ranging exploration of the natural and exact sciences, the Institute is home to scientists, students, technicians and supporting staff. Institute research efforts include the search for new ways of fighting disease and hunger, examining leading questions in mathematics and computer science, probing the physics of matter and the universe, creating novel materials and developing new strategies for protecting the environment.

UNIVERSITY PARK, Pa. — Reconstructed food webs from the Ancestral Puebloan southwestern United States show the complexity and interconnectedness of humans, other animals, crops and the environment, in an area of uncertain climate and resources, according to researchers, who think climate change and human decisions then, may shed light on future human choices.

“As southwestern archaeologists, we know that Ancestral Puebloan people were intrinsically connected to the environment,” said Stefani Crabtree, postdoctoral fellow in human behavioral ecology in the Department of Anthropology, Penn State. “But, most food webs have omitted humans.”

Traditionally, food webs, while they map the interaction of all the animals and plants in an area, usually do not emphasize the human component. Crabtree and colleagues created a digital food web that captures all categories of consumers and consumed, can be defined for specific time periods and can also represent food webs after major food sources or predators disappear from the area. If an area suddenly becomes devoid of deer or humans or corn, for example, a food web of that situation can show where predators went to find prey, or which prey thrived for lack of a predator.

These knockout food webs — webs missing a specific predator or prey — show the changes and pressures on the food sources substituted for the missing ones, or the changes that occur when pressure is removed by removing a major consumer. The researchers report the results of their study today (Apr. 10) in the Journal of Archaeological Science.

“When people show up in the area around A.D. 600 they bring corn,” said Crabtree. “It takes a while for critters to get used to it, but eventually, everything that eats vegetation, eats corn and prefers it.”

Humans bringing corn into an area is a major disruption of the existing food web. Planting corn means clearing fields to displace whatever plants and animals were there, creating a high-energy plant source of food and switching plant eaters to the preferred higher-calorie food source.

In the American Southwest, the Ancestral Puebloan people eventually preyed on their deer population enough so that they deer were no longer a reliable source of food. To compensate for this, they began to domesticate turkeys for food. Turkeys need to be fed corn if they are captive and that competes with corn for human consumption. At this time, corn made up 70 to 80 percent of Ancestral Puebloans’ food and so feeding turkeys altered the food web.

To create the food web, the team identified all the common, noninvasive species in the area. They then added species that were found in archaeological sites, but were absent from the modern lists. In some food webs, components are identified by their function, so all humming birds are considered flying pollinators, but in this case each type of humming bird received its own place in the web, linked to what it ate and what, if anything, ate it. This produced a very complicated web, but supplied exceptional redundancy.

 

“In the insect world it is harder to get at the data,” said Crabtree. “We have not been able to get at good databases so we aggregate at the functional level— pollinators or bloodsuckers for example.”

The exception to individual web entries then are invertebrates — insects, spiders, snails, etc. — that were classified by their function. Invertebrates are organized to the level of order and then grouped by function. With insects, for example, the researchers would group butterflies and moths that pollinated and sipped nectar, together in one group.

The overall food web had 334 nodes representing species or order-level functional groups with 11,344 links between predator and prey.

The researchers realize that there are differences in the environment between now and the Ancestral Puebloan period, but many things, such as pinon-juniper woodlands and sage flats are the same. Enough similarity exists for this approach to work.

The team did not produce just one overall food web, but also food webs corresponding to three archaeological locations and three time periods of Ancestral Pueblo occupation in the area — Grass Mesa Pueblo for Pueblo I, Albert Porter Pueblo for Pueblo II and Sand Canyon Pueblo for Pueblo III. They began with using archaeological assemblages from these sites incorporating all human prey and all human predators into the food web. Then they included the prey of the primary prey of humans and then predators of these human-prey species. Prey, in this case, includes animals, insects and plants.

When creating knockout food webs, the researchers included only those species that were found in reasonable quantities in the archaeological assemblages at those times.

“Knockout food webs are one of the best ways to understand how people interact with the environment,” said Crabtree. “Because we can remove something, predator or prey, and see what would happen.”

When major changes in climate variables such as drought, heat and lack of snowpack are factored in, the balance in the food web may become unstable. When food becomes scarce, most mobile creatures, animals and insects move to another location. During the time of the Ancestral Puebloans, this was possible and eventually, these people moved to the area of the Rio Grande in New Mexico and other places in New Mexico and Arizona.

“We didn’t have a long-term plan during the 600 years of Ancestral Pueblo habitation in the Mesa Verde region,” said Crabtree. “We don’t have a long-term plan today either. We don’t even have a four-year plan. Some people are pushing us to look closely at climate change.”

In the past, people migrated, said Crabtree. Unless we figure out better strategies, where are we going to migrate out to? We do not have a place to go, she said.

What people plant and eat has a great effect on the environment and on ecosystems. In the end, those choices will impact human survival, according to the researchers.

This work is part of a collaboration of researchers creating resolved food webs from a variety of places. Crabtree believes that she can compare this project to others that include humans in other geographical areas to help understand ecosystems with humans in them.

Also working on this project were Lydia J.S. Vaughn, graduate student, energy and resources group, University of California, Berkeley; and Nathan T. Crabtree, U.S. Forest Services.

The National Science Foundation and the Chateaubriand Fellowship funded this research.

A previously overlooked inky inscription on a pottery shard found in Israel calls for the delivery of more wine, according to a new study, showing that not much has changed in 2,600 years for humanity, at least when it comes to wetting our whistles.

The pottery fragment — called an ostracon, or an ink-inscribed shard — was found in 1965 at the desert fortress of Arad in Israel. The shard was in poor condition, but researchers were able to date it to around 600 B.C., right before Nebuchadnezzar, the king of Babylon, destroyed the kingdom of Judah.

After discovering the shard, researchers noticed an ink inscription on its front, which begins with a blessing of Yahweh (a Hebrew name for God), then describes money transfers. Biblical scholars and archaeologists have extensively studied this inscription, so researchers were taken aback when they found the overlooked message on the ostracon’s backside.

While its front side has been thoroughly studied, its back was considered blank,” study co-principal investigator Arie Shaus, a doctoral student of applied mathematics and archaeology at Tel Aviv University (TAU) in Israel, said in a statement.

Revealing hidden text
The research team used multispectral imaging, a technique that uses different frequencies on the electromagnetic spectrum to capture data from an image. Study co-researcher Michael Cordonsky, a physicist at TAU, noticed the scribbled note on the ostracon’s backside.

“To our surprise, three new lines of text were revealed.” Shaus said.

Using the results from the multispectral imaging, the team deciphered 50 characters making up 17 words on the back of the shard, which had been on display at the Israel Museum for more than 50 years.

“The content of the reverse side implies it is a continuation of the text on the front side,” study co-principal investigator Shira Faigenbaum-Golovin, a doctoral student of applied mathematics at TAU, said in the statement.

Send wine
The newly discovered and translated inscription says, “If there is any wine, send … If there is any-thing (else) you need, send (= write me about it). And if there is still … gi[ve] them (an amount of) Xar out of it. And Ge’alyahu has taken a bat of sparkling (?) wine.”

“The new inscription begins with a request for wine, as well as a guarantee for assistance if the addressee has any requests of his own,” Shaus said. “It concludes with a request for the provision of a certain commodity to an unnamed person, and a note regarding a ‘bath,’ an ancient measurement of wine, carried by a man named Ge’alyahu.”

The note is “an administrative text, like most of the Arad inscriptions,” study co-researcher Anat Mendel-Geberovich, an archaeologist at TAU, said in the statement. “Its importance lies in the fact that each new line, word and even a single sign is a precious addition to what we know about the First Temple period.”

As for who the request was being made to, Mendel-Geberovich said that “many of these inscriptions are addressed to Elyashiv, the quartermaster of the fortress.”

The finding shows the power of multispectral imaging, especially its use on artifacts that have already been studied, but might have had overlooked components, the researchers said.

“This is ongoing research,” study co-researcher Barak Sober, a doctoral student of applied mathematics at TAU, said in the statement. “The future may hold additional surprises.”

The study was published online June 14 in the journal PLOS ONE.

The discovery of the 14,000-year-old village in Canada lends credence to the theory that humans arrived in North America from the coast.

Northwest Native American Fire Pit

The oral history of the Heiltsuk Nation, an Aboriginal group based on the Central Coast of British Columbia, tells of a coastal strip of land that did not freeze during the ice age, making it a place of refuge for early inhabitants of the territory. As Roshini Nair reports for the CBC, a recent archaeological discovery attests to an ancient human presence in the area associated with the tradition. While digging on British Columbia’s Triquet Island, archaeologists unearthed a settlement that dates to the period of the last ice age.
The archaeological team, supported by the Hakai Institute, sifted through meters of soil and peat before hitting upon the charred remains of an ancient hearth. Researchers painstakingly peeled away charcoal flakes, which were then carbon dated. In November, tests revealed that the hearth was some 14,000 years old, indicating that the area in which it was found is one of the oldest human settlements ever discovered in North America. Or as Randy Shore of the Vancouver Sun contextualizes, the village is “three times as old as the Great Pyramid at Giza.”
Alisha Gauvreau, a PhD student at the University of Victoria and a researcher with the Hakai Institute, presented the team’s findings at the annual meeting of the Society for American Archeology this week. She tells Shore that archaeologists also found a number of artifacts in the area: fish hooks, a hand drill for igniting fires, a wooden device for launching projectiles and a cache of stone tools near the hearth.
“It appears we had people sitting in one area making stone tools beside evidence of a fire pit,” Gauvreau says. “The material that we have recovered … has really helped us weave a narrative for the occupation of this site.”
These findings may have significant implications for our understanding of ancient human migration patterns. As Jason Daley reports for Smithsonian.com, the traditional story of human arrival to the Americas posits that some 13,000 years ago, stone-age people moved across a land bridge that connected modern-day Siberia to Alaska. But recent studies suggest that route did not contain enough resources for the earliest migrants to successfully make the crossing. Instead, some researchers say, humans entered North America along the coast.
In a radio interview with the CBC, Gauvreau says that the ancient settlement on Triquet Island “really adds additional evidence” to this theory. “[A]rchaeologists had long thought that … the coast would been completely uninhabitable and impassible when that is very clearly not the case,” she explains.
The discovery is also important to the Heiltsuk Nation, lending credence to oral traditions that place their ancestors in the region during the days of the ice age. “[I]t reaffirms a lot of the history that our people have been talking about for thousands of years,” William Housty, a member of Heiltsuk Nation, tells Nair. He added that the validation by “Western science and archeology” can help the Heiltsuk people as they negotiate with the Canadian government over title rights to their traditional territory.
