Earthquake may have destroyed Canaanite palace 3,700 years ago

Sept. 11 (UPI) — A new archaeological analysis suggests an earthquake may have destroyed a Canaanite palace 3,700 years ago.

Excavations at a large dig site outside of Tel Kabri, Israel, have revealed an impressive palatial complex. Evidence suggests the city and palace flourished during the Middle Bronze Age, from 1900 to 1700 B.C. But roughly 3,700 years ago, the palace was abandoned.

“We wondered for several years what had caused the sudden destruction and abandonment of the palace and the site, after centuries of flourishing occupation,” Assaf Yasur-Landau, co-director of the excavation, said in a news release.

“A few seasons ago, we began to uncover a trench which runs through part of the palace, but initial indications suggested that it was modern, perhaps dug within the past few decades or a century or two at most,” said Yasur-Landau, who is a professor of Mediterranean archaeology at the University of Haifa in Israel.

However, the ongoing excavations revealed the trench to be ancient, containing fallen and tilted walls and floors. Intrigued by the rift, researchers examined the stone foundations that anchored the palace’s walls and mud-brick superstructures, revealing evidence of a sizable earthquake.

“Our studies show the importance of combining macro- and micro-archaeological methods for the identification of ancient earthquakes,” he said. “We also needed to evaluate alternative scenarios, including climatic, environmental and economic collapse, as well as warfare, before we were confident in proposing a seismic event scenario.”

Researchers discovered warped floors and signs that mud bricks from the walls and ceilings suddenly caved in on many of the palace’s rooms. “It really looks like the earth simply opened up and everything on either side of it fell in,” said researcher Eric Cline, professor of classics and anthropology at the George Washington University.

“It’s unlikely that the destruction was caused by violent human activity because there are no visible signs of fire, no weapons such as arrows that would indicate a battle, nor any unburied bodies related to combat,” Cline said.

When researchers examined paleoclimate data, they found no evidence of a significant drought in the region. Excavations also failed to turn up mass graveyards, the signature of a pandemic.

During earlier excavations, researchers found evidence of one of the largest and oldest wine cellars in the Near East. More recently, while sorting through the demolished palace, researchers found several dozen more jars of wine.

Researchers detailed their analysis of the palace’s sudden collapse in a new paper, published Friday in the journal PLOS One.

“The floor deposits imply a rapid collapse rather than a slow accumulation of degraded mud bricks from standing walls or ceilings of an abandoned structure,” said study co-author Ruth Shahack-Gross, professor of geoarchaeology at the University of Haifa.

“The rapid collapse, and the quick burial, combined with the geological setting of Tel Kabri, raises the possibility that one or more earthquakes could have destroyed the walls and the roof of the palace without setting it on fire,” Shahack-Gross said.

Male lions form coalitions to protect territory, increase mating opportunities

Published

on

Oct. 16 (UPI) — Male animals must compete with one another for food, territory and mates. Despite this, male lions prefer to work with one or more partners.

To better understand the how’s and why’s of coalition-building among lions, biologists from the Wildlife Institute of India and the University of Minnesota turned to the Asian lion, a single lion population confined to the forests of India’s Gir National Park.

In a previous study, researchers were able to show that lion pairs had greater access to mating opportunities and were better able protect their territories than solitary lions.

“However, a lack of genetic data from the population at this stage had prevented us from determining if such cooperation extended to relatives only, or whether non-kin were included as well,” Stotra Chakrabarti, a postdoctoral research associate at the University of Minnesota, said in a news release.

For the latest study, published Friday in the journal Scientific Reports, researchers combined behavioral and genetic records of known mothers, offspring and siblings to better estimate the level of relatedness between cooperating lions.

The lions of Gita don’t just form pairs. Some lions form coalitions of three or four males. Researchers found lion trios and quartets were consistently composed of brothers and cousins. Their analysis also showed more than 70 percent of pairs were formed by unrelated lions.

“Forgoing mating opportunities is generally a severe evolutionary cost, unless in doing so you help related individuals,” said study co-author Joseph Bump, associate professor at the University of Minnesota. “As a consequence, this evidence supports a conclusion that large male lion coalitions are feasible only when all partners are brothers and/or cousins.”

Researchers found larger coalitions fared best, but the fitness of individual lions, the number of possibly sired offspring, was greater among pairs.

“The results of our study show that male coalitions prosper better than loners in established lion societies and this can have crucial implications for their conservation, especially when establishing new populations through reintroductions,” said YV Jhala, principal investigator of the Gir lion project and the dean of the Wildlife Institute of India.

The integration of field observations and genetic data allowed scientists to identify new forms of coalition building, including one team of lions feature a father and sun duo.

Because siblings rarely reach maturity, researchers found larger coalitions are uncommon among Gir lions, making up just 12 to 13 percent of male teams.

Scientists also determined that among pairs, related lions weren’t more likely to support one another during fights than unrelated lions.

“This shows that kin support is not the only reason why males cooperate with each other, but kin support makes the cooperation even more beneficial,” Bump said.

Overall, the findings suggest cooperation among lions is quite complex — a topic ripe for further investigation.

“We have quantified the ultimate reasons why unrelated males team up, but it would be worthwhile to investigate other aspects of male cooperation, including how their bonds are forged in the first place, how they find compatible partners, what breaks the ice between them when they first meet and how they decide who will lead and who will follow,” lead study author Chakrabarti said.

Ancient societies collapsed when leaders ignored the social contract

Published

on

Oct. 16 (UPI) — When ancient societies formerly ruled by principles of good governance failed, they failed hard.

According to a new study published in the journal Frontiers in Political Science, ancient autocracies were less likely to last, but suffered less dramatic failures.

To better understand the role of government on the success and longevity of ancient societies, researchers took an in-depth look at principles that guided the governments of four societies: the Roman Empire, China’s Ming Dynasty, India’s Mughal Empire and the Venetian Republic.

Because free and fair elections were rare or nonexistent during ancient times, researchers had to come up with an alternative for gauging good governance.

“You can’t really measure it by the role of elections, so important in contemporary democracies,” study co-author Gary Feinman, the MacArthur curator of anthropology at Chicago’s Field Museum, said in a news release. “You have to come up with some other yardsticks, and the core features of the good governance concept serve as a suitable measure of that.”

“They didn’t have elections, but they had other checks and balances on the concentration of personal power and wealth by a few individuals,” Feinman said. “They all had means to enhance social well-being, provision goods and services beyond just a narrow few, and means for commoners to express their voices.”

For the ruling elite, good governance was a sensible choice. Most successful empires depended on taxes and resources from local economies, and thus their leaders had to meet the basic needs of their citizens.

“There are often checks on both the power and the economic selfishness of leaders, so they can’t hoard all the wealth,” Feinman said.

Researchers found societies with governments that were reasonably responsive to their people — governments that met the definition of good governance — tended to last a bit longer than autocratic governments.

However, researchers found that when good governments turned rotten, the breakup was often uglier than the collapse of autocratic governments.

According to the study, good governments fail more dramatically because the bureaucracy is more intimately integrated with society at large.

“Social networks and institutions become highly connected, economically, socially, and politically,” Feinman said. “Whereas if an autocratic regime collapses, you might see a different leader or you might see a different capital, but it doesn’t permeate all the way down into people’s lives, as such rulers generally monopolize resources and fund their regimes in ways less dependent on local production or broad-based taxation.”

Researchers also looked at why exactly good governments fail. They found the collapse of good governments was often triggered by the rise to power of amoral leaders — leaders who ignored the social contract and abandoned their society’s ideals.

Such betrayals often precipitated or accompanied rising inequality, concentration of political power, tax evasion, crumbling infrastructure and the decline of bureaucratic institutions — a pattern researchers suggest can be observed in modern societies.

“What I see around me feels like what I’ve observed in studying the deep histories of other world regions, and now I’m living it in my own life,” said Feinman. “It’s sort of like Groundhog Day for archaeologists and historians.”

Researchers suggest their findings are a reminder that even previously successful governments and prosperous, stable societies can fail when leaders abandon a society’s core principles.

“In the cases we address, calamity could very likely have been avoided, yet, citizens and state-builders too willingly assumed that their leadership will feel an obligation to do as expected for the benefit of society,” said lead study author Richard Blanton.

“Given the failure to anticipate, the kinds of institutional guardrails required to minimize the consequences of moral failure were inadequate,” said Blanton, a professor emeritus of anthropology at Purdue University.
