Archaeologists Date Stone-tipped Weapons: 500,000 Years Old




This is a ~500,000-year-old point from Kathu Pan 1. Multiple lines of evidence indicate that points from Kathu Pan 1 were used as hafted spear tips. Scale bar = 1 cm.

A collaborative study involving researchers at Arizona State University, the University of Toronto, and the University of Cape Town found that human ancestors were making stone-tipped weapons 500,000 years ago at the South African archaeological site of Kathu Pan 1 – 200,000 years earlier than previously thought. This study, "Evidence for Early Hafted Hunting Technology," is published in the November 16 issue of the journal Science.

Attaching stone points to spears (known as "hafting") was an important advance in hunting weaponry for early humans. Hafted tools require more effort and foreplanning to manufacture, but a sharp stone point on the end of a spear can increase its killing power.

"There is a reason that modern bow-hunters tip their arrows with razor-sharp edges. These cutting tips are extremely lethal when compared to the effects from a sharpened stick. Early humans learned this fact earlier than previously thought," said Benjamin Schoville, a coauthor of this study affiliated with the Institute of Human Origins, a research center of the College of Liberal Arts and Sciences at Arizona State University

Hafted spear tips are common in Stone Age archaeological sites after 300,000 years ago. This study shows that hafted spear tips were also used in the early Middle Pleistocene, a period associated with Homo heidelbergensis, the last common ancestor of Neandertals and modern humans.

"Rather than being invented twice, or by one group learning from the other, stone-tipped spear technology was in place much earlier," said Schoville. "Although both Neandertals and humans used stone-tipped spears, this is the first evidence that this technology originated prior to or near the divergence of these two species."

"It now looks like some of the traits that we associate with modern humans and our nearest relatives can be traced further back in our lineage," said Jayne Wilkins, lead author from the University of Toronto. "This changes the way we think about early human adaptations and capacities before the origin of our own species."

Point function was determined by comparing wear on the ancient points to damage inflicted on modern experimental points used to spear a springbok carcass target with a calibrated crossbow. This method has been used effectively to study weaponry from more recent contexts in the Middle East and southern Africa.

"When points are used as spear tips, there is a lot of damage that forms at the tip of the point, and large distinctive fractures form. The damage on these ancient stone spear points is remarkably similar to those produced with our calibrated crossbow experiment, and we demonstrate they are not easily created from other processes," said coauthor Kyle Brown, a skilled stone tool replicator from the University of Cape Town.

The points were recovered during 1979 excavations by Peter Beaumont of the McGregor Museum, Kimberly, South Africa.

In 2010, a team directed by coauthor Michael Chazan from the University of Toronto reported that the point-bearing deposits at KP1 dated to around 500,000 years ago using optically stimulated luminescence and U-series/electron spin resonance methods. The dating analyses were carried out by Naomi Porat, Geological Survey of Israel, and Rainer Grün, Australian National University.

Tel Aviv University researchers have uncovered a unique 11th-century BCE sacred compound at the site of Tel Beth-Shemesh, an ancient village that resisted the aggressive expansion of neighboring Philistines. The newly discovered sacred complex is comprised of an elevated, massive circular stone structure and an intricately constructed building characterized by a row of three flat, large round stones. Co-directors of the dig Prof. Shlomo Bunimovitz and Dr. Zvi Lederman of TAU's Sonia and Marco Nadler Institute of Archaeology say that this temple complex is unparalleled, possibly connected to an early Israelite cult — and provides remarkable new evidence of the deliberate desecration of a sacred site.

The village of Beth-Shemesh frequently changed hands between the ambitious Philistines and the Canaanite and Israelite populations that resisted them. The temple and its history reflect the power struggles that defined the region in the 12th-11th century BCE, say Prof. Bunimovitz and Dr. Lederman. Their findings will be presented this month at the annual meeting of the American Schools of Oriental Research in Chicago.

In the archaeological record, there are no parallels to this Canaanite or Israelite sacred compound of the period, note the researchers. Research has revealed that the temple has a rich history steeped in conflict. Excavators determined that the temple was not only destroyed, but also desecrated. More intensive scientific analysis of the site, conducted by geoarchaeolgist Dr. Shawn Bubel of the University of Lethbridge in Alberta, Canada, has shown that the temple ruins were used as animal pens, maybe by the invading Philistines.

After ruling out the use of the site as a domestic structure, the researchers knew that they had found something unique. Excavations revealed almost only shards of painted chalices and goblets found spread on the floor but no traces of domestic use. One of the three flat stones was surrounded by animal bone remnants, and the two other stones were seemingly designed to direct liquids. These clues convinced Prof. Bunimovitz and Dr. Lederman that they had uncovered a likely place of sacred worship.

But the temple didn't remain sacred. Samples of earth taken from layers above the destroyed temple and analyzed at the Weizmann Institute of Science revealed astonishing results. Directly above the temple was a packed-in layer containing phytoliths (remains of weeds that are commonly eaten by livestock) and spherulites (microscopic remnants of manure produced by grass-eating animals), indicating the presence of animal pens directly on top of the sacred site, explains Prof. Bunimovitz. Intermittent burning in order to clean the pens likely resulted in the concentrated state of the layer.

This desecration was no accident or coincidence, the researchers believe. Instead, it represents the see-saw of political might between the Philistines and the local population. Presumably the Philistines gained temporary control of Beth-Shemesh, and brought in livestock to live on what they knew had been a sacred site to their enemies.

Preserving tradition

According to Prof. Bunimovitz and Dr. Lederman, this discovery also serves to illuminate the recent discovery of a number of round clay ovens, called "tabuns," in the layer excavated above the temple. Typically, such ovens were located in a domestic building for food preparation, explains Prof. Bunimovitz. But these particular ovens were not part of a neighborhood or living quarter.

When the temple was discovered directly underneath, a plausible explanation for the mysterious ovens emerged. "We believe that ancestors of those who had built the original complex came back to rebuild the site," says Dr. Lederman, who suspects that the ovens were used to cook celebration feasts held in veneration of the old temple. Thus, despite the desecration of the temple by the Philistines, the memory of the sacred site survived. Once the Philistines withdrew from the area, the descendents of the original worshippers returned to commemorate this sacred place.

The researchers are now looking for additional funding to help further the excavation and analysis of this unique and surprising sacred site, which has only been partially unearthed.




Ancient Measuring System Uncovered

A team of archeologists and mathematicians from Tel Aviv University has discovered a unique, ancient system of calculating volume that differs significantly from the metric system we use today. The method appears to have been used by Egyptians and Phoenicians from the 14th to the 10th century BCE. It allowed merchants (and their clients) to accurate estimate the amount of oil, wine and other products stored in spherical containers and was entirely based on the sphere rather than the cube as a way to measure length and volume.


The Hekat and the Royal Cubit


Until this discovery archeologists believed merchants in antiquity had no accurate, standardized way of measuring the volume of fluids transported in ceramic vessels. However, digital analysis of hundreds of pots and jars found at Tel Megiddo and other sites across the Middle East revealed a strong correlation between the size and volume of these containers. The discovery was made by Professor Itzhak Benenson, head of the Department of Geography and the Human Environment at Tel Aviv University, researcher Elena Zapassky and Professor Israel Finkelstein and Dr. Yuval Gadot from the Department of Archeology.

Ancient Egyptians used a measuring unit called the "royal cubit", equivalent to approximately 52 centimeters, to measure length, and a "hekat", equivalent of approximately 5 liters, to measure volume. When TAU researchers began to measure ceramic vessels in cubits and hekats rather than meters and liters they came across an astounding discovery. Vessels with a circumference of one royal cubit could hold approximately half a hekat's worth of liquid. The correlation, repeated across hundreds of containers, is very unlikely to be accidental and indicates Ancient Egyptians had a method of accurately measuring liquid in a spherical container.


Standardization in the Ancient World


This Egyptian measuring system was adopted by Phoenicians and was still used in the area long after the fall of Egypt's New Kingdom in the late 12th century BCE. Researchers believe this is yet another indication of Egypt's immense political and cultural influence over the region, as it wasn't until the Assyrian conquest – in the 8th century BCE – that new measuring systems were introduced. Interestingly, as the royal cubit and the hekat were slowly phased out, the shapes and sizes of vessels used for transport and trade changed in accordance with new, Assyrian, measurement systems.

Neandertals might have produced sophisticated tools, body ornaments



A population of Neandertals produced sophisticated bone tools and body ornaments more than 40,000 years ago, a study finds. Jean-Jacques Hublin and colleagues analyzed bone samples from two sites in France: Grotte du Renne and Saint Césaire, where Neandertal remains are associated with artifacts from a period called the Châtelperronian.

The researchers extracted collagen from the samples and performed radiocarbon dating using an accelerator mass spectrometer. At Grotte du Renne, the Châtelperronian artifacts were dated to between 44,500 and 41,000 years ago, and a Neandertal tibia bone from Saint Césaire was found to date close to 41,950 years ago. These ages are significant because modern humans replaced the last known European Neandertals starting around 50,000 years ago. Given the dating results, the authors conclude that Neandertals must have made the bone tools and body ornaments found at the sites.

The findings contradict prior research that concluded that modern humans made the Châtelperronian items. However, because Neandertals produced body ornaments only after modern humans arrived in neighboring regions, cultural exchange likely took place between modern humans and Neandertals, according to the authors.

Extreme weather preceded collapse of Maya civilization



Decades of extreme weather crippled, and ultimately decimated, first the political culture and later the human population of the ancient Maya, according to a new study by an interdisciplinary team of researchers that includes two University of California, Davis, scientists.

The collapse of the Maya is one of the world's most enduring mysteries. Now, for the first time, researchers have combined a precise climatic record of the Maya environment with a precise record of Maya political history to provide a better understanding of the role weather had in the civilization's downfall.

Their findings are published in the Nov. 9, 2012 issue of the journal Science.

"Here you had an amazing state-level society that had created calendars, magnificent architecture, works of art, and was engaged in trade throughout Central America," said UC Davis anthropology professor and co-author Bruce Winterhalder. "They were incredible craftspersons, proficient in agriculture, statesmanship and warfare—and within about 80 years, it fell completely apart."

To determine what was happening in the sociopolitical realm during each of those years, the study tapped the extensive Maya Hieroglyphic Database Project, run by UC Davis Native American Language Center director and linguist Martha Macri, a specialist in Mayan hieroglyphs who has been tracking the culture's stone monuments for nearly 30 years.

"Every one of these Maya monuments is political history," said Macri.

Inscribed on each monument is the date it was erected and dates of significant events, such as a ruler's birthday or accession to power, as well as dates of some deaths, burials and major battles. The researchers noted that the number of monuments carved decreased in the years leading to the collapse.

But the monuments made no mention of ecological events, such as storms, drought or references to crop successes or failures.

For that information, the research team collected a stalagmite from a cave in Belize, less than 1 mile from the Maya site of Uxbenka and about 18 miles from three other important centers. Using oxygen isotope dating in 0.1 millimeter increments along the length of the stalagmite, the scientists uncovered a physical record of rainfall over the past 2,000 years.

Combined, the stalagmite and hieroglyphs allowed the researchers to link precipitation to politics. Periods of high and increasing rainfall coincided with a rise in population and political centers between 300 and 660 AD. A climate reversal and drying trend between 660 and 1000 AD triggered political competition, increased warfare, overall sociopolitical instability, and finally, political collapse. This was followed by an extended drought between 1020 and 1100 AD that likely corresponded with crop failures, death, famine, migration and, ultimately, the collapse of the Maya population.

"It has long been suspected that weather events can cause a lot of political unrest and subject societies to disease and invasion," Macri said. "But now it's clear. There is physical evidence that correlates right along with it. We are dependent on climatological events that are beyond our control."

Said Winterhalder: "It's a cautionary tale about how fragile our political structure might be. Are we in danger the same way the Classic Maya were in danger? I don't know. But I suspect that just before their rapid descent and disappearance, Maya political elites were quite confident about their achievements."

A Neolithic well uncovered in the Jezreel Valley




A rare well dating to the Neolithic period was uncovered in recent excavations the Israel Antiquities Authority carried out at ‘Enot Nisanit’, along the western fringes of the Jezreel Valley prior to enlarging Ha-Yogev Junction (Highway 66) by the National Roads Company. Archaeologists estimate the well was built approximately 8,500 years ago.

During the excavations the skeletal remains of a woman approximately 19 years of age and a man older than her were uncovered deep inside the well. How did these come to be in the well? Was this an accident or perhaps murder? As of now the answer to this question remains a mystery.

According to Yotam Tepper, excavation director on behalf of the Israel Antiquities Authority, “What is clear is that after these unknown individuals fell into the well it was no longer used for the simple reason that the well water was contaminated and was no longer potable”.

Tepper adds, “The impressive well that was revealed was connected to an ancient farming settlement and it seems the inhabitants used it for their subsistence and living. The upper part of the well was built of stones and its lower part was hewn in the bedrock. Two capstones, which narrowed the opening, were set in place at the top of the well. It is c. 8 meters deep and its upper part measures about 1.3 meters in diameter”.

Tepper says, “Numerous artifacts indicating the identity of the people who quarried it – the first farmers of the Jezreel Valley – were recovered from inside the well. The finds include, among other things, deeply denticulated sickle blades knapped from flint which were used for harvesting, as well as arrow heads and stone implements. The excavation of the accumulations in the well shaft yielded animal bones, organic finds and charcoal which will enable future studies about the domestication of plants and animals, and also allow researchers to determine the exact age of the well by means of advanced methods of absolute dating”.

“The well that was exposed in the Jezreel Valley reflects the impressive quarrying ability of the site’s ancient inhabitants and the extensive knowledge they possessed regarding the local hydrology and geology which enabled them to quarry the limestone bedrock down to the level of the water table. No doubt the quarrying of the well was a community effort that lasted a long time”, said Tepper.

According to Dr. Omri Barzilai, head of the Prehistory Branch of the Israel Antiquities Authority, “Wells from this period are unique finds in the archaeology of Israel, and probably also in the prehistoric world in general. The two oldest wells in the world were previously exposed in Cyprus and they indicated the beginning of the domestication phenomenon: it seems that ancient man tried to devise ways of protecting his drinking water from potential contamination by the animals he raised, and therefore he enclosed the water in places that were not accessible to them. The wells had another important advantage: quarrying them provided access to an available source of water that was not dependent upon springs or streams. Another well, which is about 1,000 years later than those in Cyprus, was previously exposed at the Atlit Yam site in Israel, and another well from this period has now been exposed at the ‘Enot Nisanit’ site. The exposure of these wells makes an important contribution to the study of man’s culture and economy in a period when pottery vessels and metallic objects had still not yet been invented”.

Same Scribe's Works Found Among Dead Sea Scrolls At Qumran and At Masada




Qumran


Recently Ada Yardeni, the foremost paleographer working in Israel today, made a startling claim: More than 50 Dead Sea Scroll manuscripts were copied by the same scribe.1 The 54 manuscripts came from six different caves: Qumran Caves 1, 2, 3, 4, 6 and 11. Even more surprising, Yardeni identified the same scribal hand in a manuscript of the Joshua Apocryphon found 30 miles south of Qumran at the famous desert fortress of Masada, the last holdout in the Jewish revolt against Rome.

“It seems likely that some manuscripts from Qumran were carried south by refugees fleeing the Roman destruction of Qumran in 68 C.E. [Masada is south of Qumran]. But that’s only a best guess.”
