New Evidence on the Antikythera Mechanism

The Antikythera Mechanism was recovered in about 1901 and is believed to date from about 200 BC. Its complicated gear mechanism is believed to have been used to generate calendars or predict astronomical events. The technology never spread to benefit ordinary people. It was forgotten and mechanical gears had to be re-invented.
The Antikythera Mechanism raises a question: how is it that technologies with the potential to benefit humankind can fail to be adopted? This issue of the causes of technology adoption is an important issue for economic growth.

(p. D3) A riddle for the ages may be a small step closer to a solution: Who made the famed Antikythera Mechanism, the astronomical calculator that was raised from an ancient shipwreck near Crete in 1901?
. . .
. . . a new analysis of the dial used to predict eclipses, which is set on the back of the mechanism, provides . . . another clue to one of history’s most intriguing puzzles. Christián C. Carman, a science historian at the National University of Quilmes in Argentina, and James Evans, a physicist at the University of Puget Sound in Washington, suggest that the calendar of the mysterious device began in 205 B.C., just seven years after Archimedes died.
. . .
Starting with the ways the device’s eclipse patterns fit Babylonian eclipse records, the two scientists used a process of elimination to reach a conclusion that the “epoch date,” or starting point, of the Antikythera Mechanism’s calendar was 50 years to a century earlier than had been generally believed.
. . .
. . . Archimedes was killed by a Roman soldier in 212 B.C., while the commercial grain ship carrying the mechanism is believed to have sunk sometime between 85 and 60 B.C. The new finding suggests the device may have been old at the time of the shipwreck, but the connection to Archimedes now seems even less likely.
An inscription on a small dial used to date the Olympic Games refers to an athletic competition that was held in Rhodes, according to research by Paul Iversen, a Greek scholar at Case Western Reserve University.
“If we were all taking bets about where it was made, I think I would bet what most people would bet, in Rhodes,” said Alexander Jones, a specialist in the history of ancient mathematical sciences at New York University.

Oldest Outlines of Human Hands Found in Indonesia

(p. A17) A team of researchers reported in the journal Nature on Wednesday [October 8, 2014] that paintings of hands and animals in seven limestone caves on the Indonesian island of Sulawesi may be as old as the earliest European cave art.
. . .
The researchers said the earliest images, with a minimum age of 39,900 years, are the oldest known stenciled outlines of human hands in the world. Blowing or spraying pigment around a hand pressed against rock surfaces would become a common practice among cave artists down through the ages — . . .

Greenpeace Desecrates Fragile, Ancient Hummingbird Etching in Peru

(p. A7) CARACAS, Venezuela — An expression of concern by the environmental group Greenpeace about the carbon footprint was marred this week by real footprints — in a fragile, and restricted, landscape near the Nazca lines, ancient man-made designs etched in the Peruvian desert.
The Peruvian authorities said activists from the group damaged a patch of desert when they placed a large sign that promoted renewable energy near a set of lines that form the shape of a giant hummingbird.
. . .
. . . the Peruvian authorities were seething over the episode, which they said had scarred one of the country’s most treasured national symbols.
. . .
“The hummingbird was in a pristine area, untouched,” Mr. Castillo said. “Perhaps it was the best figure.”
Mr. Castillo said that the culture ministry had sent out a team with drone aircraft equipped with cameras so that they could evaluate the damage without entering the delicate area.
He said that the harm was both physical and symbolic.
“This stupidity has co-opted part of the identity of our heritage that will now be forever associated with the scandal of Greenpeace,” he said.

45,000 Year Old Human Genome Sequenced

(p. A14) Scientists have reconstructed the genome of a man who lived 45,000 years ago, by far the oldest genetic record ever obtained from modern humans. The research, published on Wednesday [October 22, 2014] in the journal Nature, provided new clues to the expansion of modern humans from Africa about 60,000 years ago, when they moved into Europe and Asia.
And the genome, extracted from a fossil thighbone found in Siberia, added strong support to a provocative hypothesis: Early humans interbred with Neanderthals.
“It’s irreplaceable evidence of what once existed that we can’t reconstruct from what people are now,” said John Hawks, a paleoanthropologist at the University of Wisconsin who was not involved in the study. “It speaks to us with information about a time that’s lost to us.”
. . .
By comparing the Ust’-Ishim man’s long stretches of Neanderthal DNA with shorter stretches in living humans, Dr. Paabo and his colleagues estimated the rate at which they had fragmented. They used that information to determine how long ago Neanderthals and humans interbred.
Previous studies, based only on living humans, had yielded an estimate of 37,000 to 86,000 years. Dr. Paabo and his colleagues have now narrowed down that estimate drastically: Humans and Neanderthals interbred 50,000 to 60,000 years ago, according to the new data.

New Details on Babylonian Version of Noah’s Ark

(p. C8) Mr. Finkel, a curator of cuneiform inscriptions at the British Museum, details his own long-standing fascination with the ark and that of his British Museum predecessors. First among these was George Smith, who in 1872, at age 32, deciphered a clay tablet that demonstrated that 1,000 years before the likely composition of the Book of Genesis, ancient Babylonians had been brooding over the same story of divine retribution that we find in the biblical account of Noah. So great was Smith’s shock that, on confirmation, he began to run about the room tearing off his clothes.
. . .
The tablets containing what we now know as the Epic of Gilgamesh were unearthed in the ruins of Nineveh, capital of the last great Assyrian king, Ashurbanipal, who was an avid collector of texts. His famous library was torched in 612 B.C., but, as Mr. Finkel points out, “fire to a clay librarian” is not the disaster it is to one who studies works on paper. Fired clay tablets endure, and nothing, Mr. Finkel assures us, can equal the thrill of digging one out from the earth like a potato.
But the most important tablet of Mr. Finkel’s career didn’t come from the ground. It was delivered to him in 1985 by a man named Douglas Simmonds, who brought in a number of cuneiform tablets collected by his father, a member of the Royal Air Force in the Middle East at the end of World War II. One of these–an iPhone-shaped tablet–had what was recognizably the first lines of a Babylonian flood narrative, but the rest was illegible at a superficial glance, and Simmonds was reluctant to leave the tablet at the museum for analysis. It wasn’t until 2009 that Mr. Finkel was able to borrow this treasure and undertake a meticulous study, which revealed an “instruction manual for building an ark” in the tablet’s 60 lines.
. . .
So then what was the Ark Tablet for? It is puzzling that it contains no narrative, listing rather shape, size, materials and their quantities. Attractive though it may be to think it was a hand-held guide for the boat builder, Mr. Finkel suggests instead that it served as an aide-mémoire for an itinerant storyteller. The detail is explained by audience demand: No one wants to be put on the spot with difficult “how” questions when facing an audience who knew all about building coracles. Ancient audiences, it seems, were as intrigued–and as skeptical–about the ark as we are.

Global Warming Tipping Point Models Are “Overblown”

(p. C3) Climate models for north Africa often come to contradictory conclusions. Nonetheless, mainstream science holds that global warming will typically make wet places wetter and dry places drier–and at a rapid clip. That is because increased greenhouse gases trigger feedback mechanisms that push the climate system beyond various “tipping points.” In north Africa, this view suggests an expanding Sahara, the potential displacement of millions of people on the great desert’s borders and increased conflict over scarce resources.
One scientist, however, is challenging this dire view, with evidence chiefly drawn from the Sahara’s prehistoric past. Stefan Kröpelin, a geologist at the University of Cologne, has collected samples of ancient pollen and other material that suggest that the earlier episode of natural climate change, which created the Sahara, happened gradually over millennia–not over a mere century or two, as the prevailing view holds. That is why, he says, the various “tipping point” scenarios for the future of the Sahara are overblown.
The 62-year-old Dr. Kröpelin, one of the pre-eminent explorers of the Sahara, has traveled into its forbidding interior for more than four decades. Along the way he has endured weeklong dust storms, a car chase by armed troops and a parasitic disease, bilharzia, that nearly killed him.
. . .
. . . Dr. Kröpelin’s analysis of the Lake Yoa samples suggests that there was no tipping point and that the change was gradual. He says that his argument is also supported by archaeological evidence. Digs in the Sahara, conducted by various archaeologists over the years, indicate that the people of the region migrated south over millennia, not just in a few desperate decades. “Humans are very sensitive climate indicators because we can’t live without water,” he says. If the Sahara had turned to desert quickly, the human migration pattern “would have been completely different.”

Young Inca Woman Was Probably Murdered

Hobbes famously wrote that for most of human existence, life has been “poor, nasty, brutish, and short.” Further evidence:

(p. D4) Scientists who have examined the mummy of a young Inca say that her death was most likely a homicide and that it was not because of Chagas disease, the tropical parasitic infection that she had.

Hunter-Gatherers Had High Child Mortality and Died Before Age 40

(p. 31) Child mortality in foraging tribes was severe. A survey of 25 hunter-gatherer tribes in historical times from various continents revealed that, on average, 25 percent of children died before they were 1, and 37 percent died before they were 15. In one traditional hunter-gatherer tribe, child mortality was found to be 60 percent. Most historical tribes had a population growth rate of approximately zero. This stagnation is evident, says Robert Kelly in his survey of hunting-gathering peoples, because “when formerly mobile people become sedentary, the rate of population growth increases.” All things being equal, the constancy of farmed food breeds more people.
While many children died young, older hunter-gatherers did not have (p. 32) it much better. It was a tough life. Based on an analysis of bone stress and cuts, one archaeologist said the distribution of injuries on the bodies of Neanderthals was similar to that found on rodeo professionals–lots of head, trunk, and arm injuries like the ones you might get from close encounters with large, angry animals. There are no known remains of an early hominin who lived to be older than 40. Because extremely high child mortality rates depress average life expectancy, if the oldest outlier is only 40, the median age was almost certainly less than 20.

Heart Disease Affected Ancients Who Differed in Culture, Class and Diet

(p. A4) SAN FRANCISCO–It turns out there is nothing new about heart disease.

Researchers who examined 137 mummies from four cultures spanning 4,000 years said Sunday they found robust evidence of atherosclerosis, or hardening of the arteries, challenging widely held assumptions that cardiovascular disease is largely a malady of current times.
An international research team of cardiologists, radiologists and archeologists used CT scanners to evaluate the mummies, hunting for deposits of calcium in arterial walls that are a telltale sign of hardening of the arteries that can lead to heart attacks and strokes. They found that 47, or 34%, of the mummies had such deposits, suggesting, they said, that cardiovascular disease was more common in historic times than many experts think.
. . .
The same researchers reported similar findings in 2009 from Egyptian mummies. Because those specimens were believed to have been from the upper echelons of society, the researchers surmised their calcified arteries could have developed from high-fat diets. But by expanding the research to other cultures, including Puebloans of what is now the U.S. Southwest, the researchers believe all levels of society were at risk, regardless of diet.

Early Societies Were Violent, Superstitious and Unfair

(p. 89) Human nature is malleable. We use our minds to change our values, expectations, and definition of ourselves. We have changed our nature since our hominin days, and once changed, we will continue to change ourselves even more. Our inventions, such as language, writing, law, and science, have ignited a level of progress that is so fundamental and embedded in the present that we now naively expect to see similar good things in the past as well. But much of what we consider “civil” or even “humane” was absent long ago. Early societies were not peaceful but rife with warfare. One of the most common causes of adult death in tribal societies was to be declared a witch or evil spirit. No rational evidence was needed for these superstitious accusations. Lethal atrocities for infractions within a clan were the norm; fairness, as we might think of it, did not extend outside the immediate tribe. Rampant inequality among genders and physical advantage for the strong guided a type of justice few modern people would want applied to them.
