Roundup: Digging up the Past

.
"Ancient Ancestors Come to Life," National Geographic, January 3, 2014

See our ancient ancestors come to life through paleoartist John Gurche's realistic human likenesses for the Smithsonian's Hall of Human Origins.
"The human story is really nothing short of the story of a little corner of the universe becoming aware of itself," says Gurche.>>>

Louise Iles, "Year in digs: How 2013 looked in archaeology," BBC, December 31, 2013

. . . . This year's research also gave us a glimpse into the private lives of our hominid cousins, reopening debates that might shed light on the evolution of our species.

The first complete Neanderthal genome was published, at the same time showing inbreeding within Neanderthal groups as well as reports of interbreeding between Neanderthals and anatomically modern humans.>>>

Got Lactase?

Randall Stephens

In a recent issue of Nature, Andrew Curry offers up the latest theories on milk and civilization in the West.  How and why did ancient herders supplement their diets with cheese roughly 6,800 to 7,400 years ago?  Who were these early cheese makers? What were the results of the new cheese diet and the later reliance on milk?

Says Curry:

farming started to replace hunting and gathering in the Middle East around 11,000 years ago, cattle herders learned how to reduce lactose in dairy products to tolerable levels by fermenting milk to make cheese or yogurt. Several thousand years later, a genetic mutation spread through Europe that gave people the ability to produce lactase — and drink milk — throughout their lives. That adaptation opened up a rich new source of nutrition that could have sustained communities when harvests failed.

Jamestown Cannibalism Roundup


Joseph Stromberg, "Starving Settlers in Jamestown Colony Resorted to Cannibalism New archaeological evidence and forensic analysis reveals that a 14-year-old girl was cannibalized in desperation," Smithsonian, May 1, 2013

The harsh winter of 1609 in Virginia’s Jamestown Colony forced residents to do the unthinkable. A recent excavation at the historic site discovered the carcasses of dogs, cats and horses consumed during the season commonly called the “Starving Time.” But a few other newly discovered bones in particular, though, tell a far more gruesome story: the dismemberment and cannibalization of a 14-year-old English girl.>>>

 raherrmann, "Digging Out My Cannibal Girl Hat," The Junto blog, May 2, 2013

. . . . So, funny story. When I first submitted my article on cannibalism and the Starving Time at Jamestown to the William and Mary Quarterly, the piece strongly argued against any occurrence of cannibalism. When I got my readers’ reports back, Editor Chris Grasso pointed out that I didn’t really have the evidence to convincingly make that claim. He said that he’d accept the article only if I agreed to temper the argument—which was really fine with me because the main point of the essay was to ask why the stories of cannibalism mattered, not to argue for or against the existence of cannibalism in colonial Virginia.>>>

Jane O'Brien, "'Proof' Jamestown settlers turned to cannibalism," BBC News, May 1, 2013

Newly discovered human bones prove the first permanent English settlers in North America turned to cannibalism over the cruel winter of 1609-10, US researchers have said.

Scientists found unusual cuts consistent with butchering for meat on human bones dumped in a rubbish pit.>>>

"Starving Jamestown settlers turned to cannibalism," Telegraph, May 2, 2013

Scientists in the US have found the first solid archaeological evidence that some of the earliest colonists at Jamestown, Virginia, survived harsh conditions by resorting to cannibalism.

Stressed Much? You’re In Good Company

Eric Schultz
.
Earlier this month, the American Psychological Association released a study called Stress in America, concluding that Millennials, 18 to 33-year-old
From "Science Nation - Teens and Stress" (NSF)
Americans, along with Gen Xers (34-47), are the most stressed generations in America.  On a scale of 1-10, the average American defines a healthy level of stress as 3.6 but feels a level of 4.9.  Millennials and Gen Xers are at 5.4, a level the study concludes is “far higher than Boomers’ average stress level of 4.7 and Matures’ [67 and over] of 3.7.”


Thirty-nine percent of Millennials say their stress has increased in the last year, while 52 percent report having lain awake at night in the past month due to stress.  “Millennials and Gen Xers are most likely to say that they are stressed by work, money and job stability, while Boomers and Matures are more likely to be concerned with health issues affecting their families and themselves,” the study concluded.

A Real National Treasure: Rediscovering the Roanoke Colony

Heather Cox Richardson

Ok, I confess to loving the National Treasure movies. I know, I know, they’re stupid, and they completely twist history, and all that, but they are so much fun! Wouldn’t it be great if there really were hidden passages behind Mount Rushmore? Caches of historical treasures buried under modern cities? Old documents that held secret information, revealing the answers to ancient mysteries?

Oh, wait . . .

Perhaps there are, on that last one.

One of America’s great mysteries has been the fate of the Roanoke Colony, England’s first attempt to establish a permanent settlement in the “New World.” In the mid-1580s, Sir Walter Raleigh outfitted a settlement on Roanoke Island in what is now North Carolina, just inside the Outer Banks (but what was then Virginia, named, of course, for Queen Elizabeth, the Virgin Queen). The first years of the colony under a military governor were disastrous as the governor fought with both local Indians and his own people. The one great success of the venture was its choice of illustrator and mapmaker: John White. His meticulous observations of the coastline and the peoples he encountered are invaluable pictures of the New World as seen by wide-eyed European adventurers.

Melody Burri, "Historian Nancy Hewitt to present new work on Quaker Amy Post," MPNnow, August 22, 2012

Farmington, N.Y. - Nancy A. Hewitt, Professor of History and Women's Studies at Rutgers University, will give the fourth talk in the summer series for the 1816 Farmington Quaker Meetinghouse Museum.>>>

Professor Hewitt will present "Faith and Politics: The Spiritual Journeys of Amy Post."

Edward Helmore, "UK Harvard star Niall Ferguson accused of intellectual fraud," The Week, August 22, 2012

 THE British-born journalist and Harvard-tenured historian Niall Ferguson has landed himself in a nasty spat with some of America's most distinguished economists, among them Princeton's Nobel Prize-winner - and venerable New York Times columnist - Paul Krugman.

Ferguson is a promoter of Chancellor George Osborne's cut-to-growth economic philosophy. Krugman is a spend-to-grow man, as is President Obama.>>>

An interview with Victor Davis Hanson on his essay "There is No One California," Forum, KQED, August 20, 2012

California has become a target of mockery in the presidential campaign, with GOP challenger Mitt Romney holding the troubled state up as an example of where the country is headed under Barack Obama. Historian and conservative columnist Victor Davis Hanson also slams the state in a recent article entitled, "There is No One California." He joins us to talk about the piece, and to give us his take on the presidential campaign.>>>

Rebekah Higgitt, "(Pseudo)scientific history?" Guardian blog, August 16, 2012

There have been many writers who have claimed that history can be, or should be, scientific. Different things are meant by this, of course, and such statements are provoked by different motivations, although generally they trade on the perceived successes, rewards, professionalism and certainty of the sciences.>>>

"Historian Taylor Branch Critiques College Sports," Only a Game, WBUR (rebroadcast), August 25, 2012

The NCAA is facing growing scrutiny from college athletes, coaches and the people who follow college sports. The September 2011 issue of the Atlantic Monthly featured an article by Pulitzer-prize winning historian Taylor Branch — author of Parting the Waters, The Clinton Tapes, and others — entitled “The Shame of College Sports,” which criticizes the corruption within the NCAA.>>>

History, Gender, and Sexuality Roundup

.
Lisa Hilton, "Mistresses through the ages Prostitute, concubine, mistress, wife: the boundaries are blurred in this study," TLS, February 9, 2011

What is a mistress? Elizabeth Abbott, who has also published A History of Celibacy and held the post of Dean of Women at Trinity College, University of Toronto, offers this definition: “a woman voluntarily or forcibly engaged in a relatively long-term sexual relationship with a man who is usually married to another woman”. Given the persistence of this model across time and cultures, Abbott maintains that “mistressdom”, like celibacy, is therefore an essential means by which to consider sexual relationships outside marriage – “in fact, an institution parallel and complementary to marriage”. Considering the media’s current obsession with love-rat footballers and cheating celebs, “mistressdom” might also be considered a safe bet for a publisher’s list, and Abbott duly provides us with a generally cheerful tumble through adultery down the ages.>>>

Elizabeth Varon, "Women at War," NYT, February 1, 2011

What do women have to do with the origins of the Civil War? Growing up in Virginia in the 1970s, I often heard this answer: nothing.

Much has changed since then. A new generation of scholars has rediscovered the Civil War as a drama in which women, and gender tensions, figure prominently. Thanks to new research into diaries, letters, newspapers and state and local records, we now know that women were on the front lines of the literary and rhetorical war over slavery long before the shooting war began.>>>

Adam Kirsch, "Macho Man: Exodus recast Israel’s founders as swaggering heroes and secured Leon Uris a place on the Jewish bookshelf even though, as a new biography shows, he was a mediocre writer and a troubled person," Tablet, February 1, 2011

Jews take pride in calling themselves “the people of the book,” and while there’s something a little vainglorious about the phrase—all peoples have books, don’t they?—its appeal is easy to understand. For millennia, in the absence of land and power, Jews found a kind of virtual sovereignty in texts, and the history of Judaism from the Babylonian Exile onward could be written as a history of books and writers—the Torah and the Prophets, the Mishna and Gemara, Rashi and Maimonides, down to modern, secular authors like Theodor Herzl and Sholem Aleichem and Primo Levi.

And then there’s Leon Uris.>>>

Carol Tavris, "The new neurosexism," TLS, January 26, 2011

. . . . Today we look back with amusement at the efforts of nineteenth-century scientists to weigh, cut, split or dissect brains in their pursuit of finding the precise anatomical reason for female inferiority. How much more scientific and unbiased we are today, we think, with our PET scans and fMRIs and sophisticated measurements of hormone levels. Today’s scientists would never commit such a methodological faux pas as failing to have a control group or knowing the sex of the brain they are dissecting – would they? Brain scans don’t lie – do they?>>>
