Humans Swap DNA More Readily Than They Swap Stories

Jane J. Lee


Once upon a time, someone in 14th-century Europe told a tale of two girls—a kind one who was rewarded for her manners and willingness to work hard, and an unkind girl who was punished for her greed and selfishness.

This version was part of a long line of variations that eventually spread throughout Europe, finding their way into the Brothers Grimm fairytales as Frau Holle, and even into Shakespeare's The Merchant of Venice. (Watch a video of the Frau Holle fairytale.)

In a new study, evolutionary psychologist Quentin Atkinson is using the popular tale of the kind and unkind girls to study how human culture differs within and between groups, and how easily the story moved from one group to another.

Atkinson, of the University of Auckland in New Zealand, and his co-authors employed tools normally used to study genetic variation within a species, such as people, to look at variations in this folktale throughout Europe.

The researchers found that there were significant differences in the folktale between ethnolinguistic groups—or groups bound together by language and ethnicity. From this, the scientists concluded that it's much harder for cultural information to move between groups than it is for genes.

The study, published February 5 in Proceedings of the Royal Society B, found that about 9 percent of the variation in the tale of the two girls occurred between ethnolinguistic groups. Previous studies looking at the genetic diversity across groups in Europe found levels of variation less than one percent.

For example, there's a part of the story in which the girls meet a witch who asks them to perform some chores. In different renditions of the tale, the meeting took place by a river, at the bottom of a well, or in a cave. Other versions had the girls meeting with three old men or the Virgin Mary, said Atkinson.

Conformity

Researchers have viewed human culture through the lens of genetics for decades, said Atkinson. "It's a fair comparison in the sense that it's just variation across human groups."

But unlike genes, which move into a population relatively easily and can propagate randomly, it's harder for new ideas to take hold in a group, he said. Even if a tale can bridge the "ethnolinguistic boundary," there are still forces that might work against a new cultural variation that wouldn't necessarily affect genes.

"Humans don't copy the ideas they hear randomly," Atkinson said. "We don't just choose ... the first story we hear and pass it on.

"We show what's called a conformist bias—we'll tend to aggregate across what we think everyone else in the population is doing," he explained. If someone comes along and tells a story a little differently, most likely, people will ignore those differences and tell the story like everyone else is telling it.

"That makes it more difficult for new ideas to come in," Atkinson said.

Cultural Boundaries

Atkinson and his colleagues found that if two versions of the folktale were found only six miles (ten kilometers) away from each other but came from different ethnolinguistic groups, such as the French and the Germans, then those versions were as different from each other as two versions taken from within the same group—say just the Germans—located 62 miles (100 kilometers) away from each other.

"To me, the take-home message is that cultural groups strongly constrain the flow of information, and this enables them to develop highly local cultural traditions and norms," said Mark Pagel, of the University of Reading in the U.K., who wasn't involved in the new study.

Pagel, who studies the evolution of human behavior, said by email that he views cultural groups almost like biological species. But these groups, which he calls "cultural survival vehicles," are more powerful in some ways than our genes.

That's because when immigrants from a particular cultural group move into a new one, they bring genetic diversity that, if the immigrants have children, get mixed around, changing the new population's gene pool. But the new population's culture doesn't necessarily change.

Atkinson plans to keep using the tools of the population-genetics trade to see if the patterns he found in the variations of the kind and unkind girls hold true for other folktale variants in Europe and around the world.

Humans do a lot of interesting things, Atkinson said. "[And] the most interesting things aren't coded in our DNA."

Ex-LA Cop Sought in Shootings of 3 Cops, 2 Slayings













Police in Southern California say they suspect that a fired cop is connected to the shootings -- one fatal -- of three police officers this morning, as well as the weekend slayings of an assistant women's college basketball coach and her fiancé in what cops believe are acts of revenge against the LAPD as suggested in the suspect's online manifesto.


Former police officer Christopher Jordan Dorner, 33, who's a U.S. Navy reservist, has been publically named as a suspect in the killings of Monica Quan, 28, and her 27-year-old fiancé, Keith Lawrence, Irvine police Chief David L. Maggard said at a news conference Wednesday night.


Dorner is still on the loose and is considered armed and dangerous, police say.


Police said three police officers were shot early this morning: one in Corona, Calif., and two in Riverside, Calif. The Riverside Police Department said one of its officers was killed, KABC-TV reported. The conditions of the two other officers were not immediately released. Police reportedly suspect a connection to Dorner.


Lawrence was found slumped behind the wheel of his white Kia in the parking lot of their upscale apartment complex Sunday and Quan was in the passenger seat.


"A particular interest at this point in the investigation is a multi-page manifesto in which the suspect has implicated himself in the slayings," Maggard said.

Police said Dorner's manifesto included threats against members of the LAPD. Police say they are taking extra measures to ensure the safety of officers and their families.


The document, allegedly posted on an Internet message board this week, apparently blames Quan's father, retired LAPD Capt. Randy Quan, for his firing from the department.


"Your lack of ethics and conspiring to wrong a just individual are over," he allegedly wrote.


One passage from the manifesto reads, "I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty."


"I never had the opportunity to have a family of my own," Dorner wrote. "I'm terminating yours."


Dorner was with the department from 2005 until 2008, when he was fired for making false statements.


Randy Quan, who became a lawyer in retirement, represented Dorner in front of the Board of Rights, a tribunal that ruled against Dorner at the time of his dismissal, LAPD Capt. William Hayes told The Associated Press Wednesday night.


According to documents from a court of appeals hearing in October 2011, Dorner was fired from the LAPD after he made a complaint against his field-training officer, Sgt. Teresa Evans, saying in the course of an arrest she had kicked a suspect who was a schizophrenic with severe dementia.


After an investigation, Dorner was fired for making false statements.


"We have strong cause to believe Dorner is armed and dangerous," Maggard said.


Police say Dorner is 6-feet tall, and weighs 270 pounds. He has black hair and brown eyes.


Meanwhile, Cal State-Fullerton is still mourning the loss of their beloved assistant coach.


"There are really no words to convey the sadness that our program feels, that the young women who have had the privilege of working with such a bright and passionate woman," head coach Marcia Foster said earlier this week. "I want to especially send out condolences to Randal and Sylvia Quan, and her brother Ryan."


After college, Quan coached at Lutheran University in Thousand Oaks and has spent the past two years as an assistant coach at Cal State-Fullerton. The university has posted a memorial page on its sports website dedicated to Quan.


Lawrence was a business graduate who recently started working as a public-safety officer at USC.

Silver tsunami & dwindling workforce can destabilise economies: Lee Yi Shyan






SINGAPORE: Senior Minister of State for National Development and Trade & Industry Lee Yi-Shyan has painted a sobering picture of an ageing population and shrinking workforce.

Speaking in Parliament on the Population White Paper and Land Use Plan on Wednesday, Mr Lee pointed to the experience of Asian neighbours like Japan and Taiwan as examples of how the silver tsunami and dwindling workforce can destabilise economies.

For example, a city outside Nagoya called Gifu has seen shops along the main street closed for good.

In Hokkaido, in a small town called Yubari, half of the population is above 65 years old.

Mr Lee said Yubari's small working population means a measly tax base.

Four years ago, the city government went bust after owing a debt of US$315 million. The city was later forced to embark on an 18-year austerity drive.

Mr Lee said: "It retrenched half of its civil servants. Public service in the City was badly affected. The public library was gone. Six primary schools merged into one. The General Hospital closed down two thirds of its facilities to save utilities. It also halved its number of ambulances and asked its elderly patients to walk to the hospital by themselves."

The effect of two decades of economic stagnation in Japan, said Mr Lee has led to what is described as "the Waniguchi (crocodile's mouth) effect" - Soaring public expenditure coupled with a drop in tax revenue.

Mr Lee said the huge silver tsunami is destabilising Japan.

He said the country did not manage to raise its working population because it could not build a consensus to allow immigration to boost the workforce.

Similarly in Taiwan, Mr Lee pointed to an article which described the economy as "a small tax revenue country but large welfare state."

Mr Lee said Singapore is not operating in silos.

The world, he said, will continue to move forward, regardless of Singapore's demographic and internal problems.

It is against this larger picture, he said, that Singapore has to define its path forward.

Mr Lee said: "It makes sense for the nation to maintain a sustainable and stable Singaporean population while we are still young, and while external conditions are favourable."

Mr Lee noted there are lessons to be learnt from the experiences of other countries.

The number of elderly citizens in Singapore aged 65 and above will increase considerably from around 340,000 in 2011 to 900,000 by 2030.

Mr Lee cited China's rapidly ageing population to highlight issues which Singapore may face in the future.

He said: "China is beginning to see the "4-2-1" phenomenon: one child having to look after two parents and four grandparents. This inverted pyramid means a heavy burden for the children. When both parents and grandparents are retired, there is also the "aged caring for the aged" phenomenon and this is becoming common in our communities."

Echoing the sentiment, former Cabinet Minister Mah Bow Tan said Singapore cannot afford to lose its edge and become less competitive.

He urged Singaporeans to keep their hearts and minds open.

Mr Mah said: "We have spent a lot of our time looking inwards, talking about our discomforts, our space. We have not asked ourselves how we are going to compete with outside world. How we are going to earn a living to live the good life. It is almost taken from granted that the good life will continue even if growth slows. We expect new infrastructure to be rolled out, even as growth slows. We want more subsidies for health care and housing and let's have less foreign workers and a slower pace of life. Where will the revenue from all this come from?"

Mr Mah, who is MP for Tampines GRC, said government revenue comes mostly from income taxes, consumption taxes and asset taxes, all of which are dependent on economic growth.

He added Singapore needs a bigger population with better educated and trained citizens as well as talented non-residents to supplement the home-grown talent.

Women don't feel safe in Delhi: Sheila

NEW DELHI: Women do not feel safe in Delhi, chief minister Sheila Dikshit admitted Wednesday.

"Women don't feel safe in Delhi. Fears have risen. I'm shocked to learn about the Lajpat Nagar attempted rape case. It's a big setback for us," she said referring to the rape bid on a 19-year-old woman Tuesday.

The Class IX student fought off the rape bid in her own house by an electricity contractor, who thrust an iron rod into her throat to quell her cries for help. The accused has been arrested.

However, the chief minister promised to do everything possible to provide safety to women.

"My government will do everything possible to provide a conducive atmosphere for the women in the city," Dikshit said.

But CPM leader Brinda Karat criticized Dikshit.

"It is clear that women in Delhi are insecure. The chief minister is speaking the truth. But it is surely not enough. What is her responsibility as chief minister?

"Women's security issues have become political football between central and state government. Chief minister blames Delhi Police; central government defends police. It's a shame."

The Real Richard III


It's a question that actors from Laurence Olivier to Kevin Spacey have grappled with: What did Richard III, the villainous protagonist of Shakespeare's famous historical drama, really look and sound like?

In the wake of this week's announcement by the University of Leicester that archaeologists have discovered the 15th-century British king's lost skeleton beneath a parking lot, news continues to unfold that helps flesh out the real Richard III.

The Richard III Society unveiled a 3D reconstruction today of the late king's head and shoulders, based on computer analysis of his skull combined with an artist's interpretation of details from historical portraits. (Related: "Shakespeare's Coined Words Now Common Currency.")

"We received the skull data before DNA analysis confirmed that the remains were Richard III, and we treated it like a forensic case," said Caroline Wilkinson, the University of Dundee facial anthropologist who led the reconstruction project. "We were very pleasantly surprised by the results."

Though Shakespeare describes the king as an "elvish-marked, abortive, rooting hog," the reconstructed Richard has a pleasant, almost feminine face, with youthful skin and thoughtful eyes. His right shoulder is slightly higher than the left, a consequence of scoliosis, but the difference is barely visible, said Wilkinson.

"I think the whole Shakespearean view of him as being sort of monster-like was based more on his personality than his physical features," she reflected.

Look back at 125 years of National Geographic history

People are naturally fascinated by faces, especially of historical figures, said Wilkinson, who has also worked on reconstructions of J.S. Bach, the real Saint Nicholas, the poet Robert Burns, and Cleopatra's sister.

"We make judgments about people all the time from looking at their appearance," she said. "In Richard's case, up to now his image has been quite negative. This offers a new context for considering him from the point of view of his anatomical structure rather than his actions. He had quite an interesting face."

A Voice From the Past

Most people's impression of Richard's personality comes from Shakespeare's play, in which the maligned ruler utters such memorable lines as "Now is the winter of our discontent/Made glorious summer by this son of York," and "A horse! A horse! My kingdom for a horse!"

But how would the real Richard III have expressed himself? Did he have an accent? Was there any sense of personality or passion in his choice of words?

To find out more about the mysterious monarch, Philip Shaw, a historical linguist at University of Leicester's School of English, analyzed the only two known examples of Richard III's own writing. Both are postscripts on letters otherwise composed by secretaries—one in 1469, before Richard became king, and one from 1483, the first year of his brief reign.

Shaw identified a quirk of spelling that suggests that Richard may have spent time in the West Midlands, or perhaps had a tutor who hailed from there.

"I was looking to compare the way he spells things with the way his secretaries spell things, working on the assumption that he would have been schooled to a fairly high level," Shaw explained.

In the 1469 letter, Richard spells the word "will" as "wule," a variation associated with the West Midlands. But Shaw also notes that by 1483, when Richard wrote the second letter's postscript, he had changed his spelling to the more standard "wyll" (the letters 'i' and 'y' were largely interchangeable during that period of Middle English).

"That could suggest something about him brushing up over the years, or moving toward what would have been the educated standard," Shaw said, noting that the handwriting in the second example also appears a bit more polished. "One wonders what sort of practice and teaching he'd had in the interim."

Although it's hard to infer tone of voice from written letters, there is certainly emotion in the words penned by Richard III.

In the 1469 letter, the 17-year-old seeks a loan of 100 pounds from the king's undertreasurer. Although the request is clearly stated in the body of the letter, Richard adds an urgent P.S.: "I pray you that you fail me not now at this time in my great need, as you will that I show you my good lordship in that matter that you labour to me for."

That could either be a veiled threat (If you don't lend me the money, I won't do that thing you asked me to do) or friendly cajoling (Come on, I'm helping you out with something, so help me out with this loan).

"His decision to take the pen himself shows you how important that personal touch must have been in getting people to do something," Shaw said.

The second letter, written to King Richard's chancellor in 1483, also conveys a sense of urgency. He had just learned that the Duke of Buckingham—once a close ally—was leading a rebellion against him.

"He's asking for his Great Seal to be sent to him so that he can use it to give out orders to suppress the rebellion," Shaw said. "He calls the Duke 'the most untrue creature living. You get a sense of how personally let down and betrayed he feels."

Shaw said he hopes his analysis—in combination with the new facial reconstruction—will help humanize Richard III.

"He probably wasn't quite the villain that Shakespeare portrays, though I suspect he was quite ruthless," he said. "But you probably couldn't afford to be a very nice man if you wanted to survive as a king in those days."

Hostage Taker Waged Firefight With SWAT agents













Jimmy Lee Dykes, the man who held a 5-year-old boy hostage for nearly a week in an underground bunker in Alabama, had two homemade explosive devices on his property and engaged in a firefight with SWAT agents before they stormed the bunker and killed him, according to the FBI.


One explosive device was found inside the bunker and another was located in the PVC pipe negotiators used to communicate with Dykes, the FBI said Tuesday night. Both devices were "disrupted," according to the FBI.
The search for hazards is expected to continue through today.


Preliminary investigation reports indicate that Dykes engaged in a firefight with the SWAT agents who made entry, according to the FBI.


Officials were able to insert a high-tech camera into the 6-by-8-foot bunker to monitor Dykes' movements, and they became increasingly concerned that he might act out, a law enforcement source with direct knowledge of the case told ABC News Monday.


FBI special agents were positioned near the entrance of the bunker and negotiators were able to convince Dykes to approach the bunker door. FBI agents used two explosions to gain entry into the bunker. It also appears that Dykes reinforced the bunker against any attempted entry by law enforcement, according to the FBI.


ABC News has learned that Dykes first opened fired on the agents during the bunker raid. Moments later, the agents returned fire, killing Dykes.


The shooting review team continues to gather facts regarding the incident, the FBI said.

The boy, only identified as Ethan, was rescued from the scene by a waiting ambulance. The bunker raid came six days after Dykes boarded a school bus, fatally shot the driver and abducted the boy, who suffered no physical injuries.

"It's all about timing that is why you practice. You practice blowing the door in split seconds, flash bang, shoot before Mr. Dykes would even have an opportunity to react," Brad Garrett, former FBI agent and ABC News consultant, said.


Meanwhile, Ethan is set to celebrate his 6th birthday today, happily reunited with his family.


Ethan's thrilled relatives told "Good Morning America" Tuesday that he seemed "normal as a child could be" after what he went through and has been happily playing with his toy dinosaur.


"He's happy to be home," Ethan's great uncle Berlin Enfinger told "GMA." "He's very excited and he looks good."


"For the first time in almost a week, I woke up this morning to the most beautiful sight...my sweet boy. I can't describe how incredible it is to hold him again," Ethan's' mother wrote in a statement released by the FBI Tuesday.


Ethan is "running around the hospital room, putting sticky notes on everyone that was in there, eating a turkey sandwich and watching SpongeBob," Dale County Schools Superintendent Donny Bynum said at a news conference Tuesday.


When asked about a birthday party for Ethan, Bynum said, "We are still in the planning stages. Our time frame is that we are waiting for Ethan, waiting on that process, but we are going to have it at a school facility, most likely the football stadium at Dale County High School."


He said many "tears of celebration" were shed Monday night when Ethan was reunited with his family.


"If I could, I would do cartwheels all the way down the road," Ethan's aunt Debra Cook told "GMA." "I was ecstatic. Everything just seemed like it was so much clearer. You know, we had all been walking around in a fog and everyone was just excited. There's no words to put how we felt and how relieved we were."


Cook said that Ethan has not yet told them anything about what happened in the bunker and they know very little about Dykes.


What the family does know is that they are overjoyed to have their "little buddy" back.


"He's a special child, 90 miles per hour all the time," Cook said. "[He's] a very, very loving child. When he walks in the room, he just lights it up."

Strengthening security at the nation’s airports



In pursuit of safeguarding the public, Liddell, a federal security director based in Syracuse, has written a book that is now used to train TSOs. It’s called the “National Standardization Guide to Improving Security Effectiveness.” Tasks at each duty area have been inventoried and cataloged, and the “knowledge, values and skills” associated with the airport security jobs have been identified under what Liddell describes as a systems approach to training.


As important as it is to use X-ray machines and explosive trace-detection equipment and to have the correct rules and procedures in place, Liddell said transportation security relies on the skills of the people responsible for it.

“People performance is the cornerstone,” he said. “When I set out to improve things, I look at the people. I look at their proficiency, their skill in doing something and how well they’re doing that job.”

Even when people have the skills to do their jobs, they don’t necessarily do them well each time, especially when conditions can vary with each day and every passenger. To keep performance high, TSOs are tested covertly at unexpected times. A banned item will be sent through a checkpoint and the reaction and activities that take place are monitored.

Whether or not TSOs spot contraband, everyone at that checkpoint during the test participates in an “after-action” review. “It’s the learning experience that’s relevant,” Liddell said. “We’re doing a review of actual performance and you can always improve.”

Liddell is sensitive to the pressure that airport security personnel face. TSOs have the tough of performing multiple tasks under constant camera surveillance and public scrutiny, often interacting with tired or irritated travelers. The testing and training helps them continually up their game.

Thirty airports around the country that helped test the training system and now use a version of it. Paul Armes, federal security director at Nashville International Airport, was interested in creating such a system with a colleague when they both worked in Arizona, but it “never got traction.”

When he learned about what Liddell was doing, he was eager to participate. “Typical of Dan, he built it himself and practiced it so he had hard metric results, and then he started reaching out to some of us, working with his counterparts around the country to get a good representative sample,” Armes said. “He sees things others don’t see sometimes and he has the capability to drill down into the details.”

Liddell began the “pretty long process” of analyzing how people were performing at checkpoints in 2009. He sat down with subject-matter experts to produce the task inventory he now uses. In 2010, he improved the review and reporting process that occurs after covert tests events and instituted the security practices he refined at the other New York airports he oversees, including Greater Binghamton, Ithaca and four others. “I love breaking it down,” he said. “I’ve got a quest for improvement.”

In a less sneaky version of the television show, “Undercover Boss,” Liddell went through the new-hire training program for his employees to understand as much as he could about the jobs and the training provided for them, he said.

If pursuing knowledge is in Liddell’s genes, it may be because his parents were both in education. His father was a high school principal and his mother was a fifth-grade teacher. His teaching manifested itself instead in the training realm, where he strives to educate security employees as effectively as possible, inside the classroom and out.

“It’s always a challenge to meet that right balance of really great effectiveness and really great efficiency,” he said. “There are always challenges. It’s what gets me up in the morning, trying to improve.”

MDA introduces new scholarship for film-makers






SINGAPORE: The Media Development Authority (MDA) has introduced a special film category for its Media Education Scheme (MES).

The MES (Film) scholarship is tailored for screenwriters, directors and film-makers, who tend to operate on a freelance basis.

On top of full scholarship and an annual living allowance, MES (Film) scholars will be assigned to mentors who will coach, guide and provide contacts and opportunities to the recipient.

Unlike other MES scholars, film scholars will not be offered full-time employment upon graduation, but will be expected to commit to two years of service under the mentorship of their assigned film-makers.

In a written parliamentary reply to Nominated MP Janice Koh, Minister for Communications and Information Dr Yaacob Ibrahim said the new scheme is the result of consultation between MDA and the film industry, following feedback that the MES may not cater to the needs of the film industry.

The MES was revised in 2012 to include job placements for scholars with the aim of matching their talents with media companies' needs for specific skill sets.

MES scholars are offered internship and training opportunities, as well as an employment bond of three to five years upon graduation with their companies, which include MediaCorp and Singapore Press Holdings.

Shinde to bear consequences of Hindu terror remarks: BJP

NEW DELHI: Alleging that home minister Sushilkumar Shinde's Hindu terror remarks were a ploy to deflect attention from the failures of the government, BJP today said Congress will have to "bear the consequences" of this "insult" inside and outside Parliament.

The party said it will bring up this issue in Parliament in the forthcoming Budget Session and boycott of Shinde is one of the proposals it is "seriously thinking about".

BJP leader Murli Manohar Joshi told reporters here that Shinde had insulted "the nation, its tradition and its culture" by alleging that RSS and BJP were involved in training terrorists. He maintained that his remarks had benefited Pakistan-based terror groups like JuD and LeT.

"What was the need for Shinde to make these remarks at the Congress Chintan Shivir (in Jaipur)?...This only means that it was a well-thought out strategy of Congress... This is a ploy to deflect attention from his failure to improve internal security, ensure peace and secure the borders," Joshi said.

The BJP leader cited the resolution of the Committee on Sanctions of the UN Security Council passed in June 2009 that Arif Qasmani, chief coordinator of LeT, had funded the Samjhauta blast and al-Qaida had provided the manpower.

Joshi said that Pakistan interior minister Rehman Malik had stated in January 2010 that Pakistani terrorists were hired for the blast.

"You (Shinde) have insulted the entire nation and culture and tradition of this nation...Congress will have to answer (these questions) and will have to face the consequences," Joshi said.

Space Pictures This Week: A Space Monkey, Printing a Moon Base

Illustration courtesy Foster and Partners/ESA

The European Space Agency (ESA) announced January 31 that it is looking into building a moon base (pictured in an artist's conception) using a technique called 3-D printing.

It probably won't be as easy as whipping out a printer, hooking it to a computer, and pressing "print," but using lunar soils as the basis for actual building blocks could be a possibility.

"Terrestrial 3-D printing technology has produced entire structures," said Laurent Pambaguian, head of the project for ESA, in a statement.

On Earth, 3-D printing, also known as additive manufacturing, produces a three-dimensional object from a digital file. The computer takes cross-sectional slices of the structure to be printed and sends it to the 3-D printer. The printer bonds liquid or powder materials in the shape of each slice, gradually building up the structure. (Watch how future astronauts could print tools in space.)

The ESA and its industrial partners have already manufactured a 1.7 ton (1.5 tonne) honeycombed building block to demonstrate what future construction materials would look like.
