Ancient DNA Unravels Europe’s Genetic Diversity“Ancient DNA recovered from a time series of skeletons in Germany spanning 4,000 years of prehistory has been used to reconstruct the first detailed genetic history of modern-day Europeans. The study, published today in ‘Science’, reveals dramatic population changes with waves of prehistoric migration, not only from the accepted path via the Near East, but also from Western and Eastern Europe.” – orig. research article: Ancient DNA Reveals Key Stages in the Formation of Central European Mitochondrial Genetic Diversity. from dienekes: “Anyone adhering to a ‘pots not people’ paradigm will find difficult to explain the sharp discontinuities found in the genetic record.” – and here’s national geographic’s take on the story – my head’s dizzy from all the spin!: “So, just like parts of Europe today are melting pots from different living cultures across the world, Europe is also a melting pot of genetic lineages from different prehistoric cultures that lived there at different periods of time.” – see also: Stone Age farmers, hunters kept their distance.

Genes Suggest European Women at Root of Ashkenazi Family Tree“The women who founded the Ashkenazi Jewish community of Europe were not from the Near East, as previously supposed, and reinforces the idea that many Jewish communities outside Israel were founded by single men who married and converted local women.” – see dienekes and greg cochran.

Child Behaviour: Not In Their Genes?“Using a powerful approach called GCTA, King’s College London researchers Maciej Trzaskowski and colleagues found no evidence that genetics can explain differences in children’s behavioural and conduct difficulties.” – @neuroskeptic.

“Were the First Artists Mostly Women?“Three-quarters of handprints in ancient cave art were left by women, study finds.” — afaics, there’s no reason to conclude that the individuals who spray painted outlines of their hands (any idiot can do that — I could do that!) were the same individuals who painted the horses and lions, etc. duh. anyway, here’s the interesting bit from the article: “[T]he hands in the caves were much more sexually dimorphic than modern hands, meaning that there was little overlap in the various hand measurements. ‘They fall at the extreme ends, and even beyond the extreme ends,’ Snow said. ‘Twenty thousand years ago, men were men and women were women.'”

Glass always half-empty? Your genes may be to blame“UBC researcher finds some people are genetically predisposed to seeing things in a negative light. Further research is also planned to explore the gene variant’s occurrence across different ethnic groups. While it is believed more than half of Caucasians have ADRA2b, some studies suggest it is much less prominent in other ethnicities….”

Whites More Prone to Certain Heart Condition Than Other Ethnic Groups“In a study to be published online October 8 and in the November 12 issue of ‘Circulation’, researchers discovered that self-described non-Hispanic whites are more likely to develop atrial fibrillation than people from other race or ethnic groups. ‘We found that consistently, every other race had a statistically significant lower risk of atrial fibrillation compared to whites…. So this suggests that white race is itself a risk factor for atrial fibrillation.'” – h/t mr. mangan, esq!

Changes in women’s attractiveness perception of masculine men’s dances across the ovulatory cycle: Preliminary data“Women’s preferences for putative cues of genetic quality in men’s voices, faces, bodies, and behavioral displays are stronger during the fertile phase of the ovulatory cycle. Here we show that ovulatory cycle-related changes in women’s attractiveness perceptions of male features are also found with dance movements, especially those perceived as highly masculine.”

Similar chimpanzees form friendships“‘We found that, especially among unrelated friends, the most sociable and bold individuals preferred the company of other highly sociable and bold individuals, whereas shy and less sociable ones spent time with other similarly aloof and shy chimpanzees,’ says the researcher. The researchers argue that such a strong preference for self-like individuals is probably adaptive, because frequent cooperation becomes more reliable when both partners have similar behavioural tendencies and emotional states. This finding strongly resembles the known ‘similarity effect’ in humans: We tend to make friends with people who are equally extraverted, friendly and bold as ourselves.” — same in some birds, too, remember?

The Anglosphere miracle – by daniel hannan – “As for the idea that the individual should be as free as possible from state coercion, this is regarded as the ultimate Anglophone fetish. Whenever the E.U. extends its jurisdiction into a new field—decreeing what vitamins we can buy, how much capital banks must hold, what hours we may work, how herbal remedies are to be regulated—I ask what specific problem the new rules are needed to solve. The response is always the same: ‘But the old system was unregulated!’ The idea that absence of regulation might be a natural state of affairs is seen as preposterous.”

Preventing penile fractures and Peyronie’s disease – DON’T try this at home!: “In some Middle East regions, men engage in a practice known as *taqaandan* (‘to click’ in Kurdish), explains Dr. Javaad Zargooshi, urology professor at Kermanshah University of Medical Sciences in Iran. It’s a painless process, similar to knuckle-cracking, in which the top half of an erect penis is bent forcefully while the rest of the shaft is held stationary. Usually this produces only a loss of erection and a satisfying popping noise, says Zargooshi, who published a report on the phenomenon in December in the Journal of Sexual Medicine. Other times, it will fracture the penis.” – wait. what? – via ed west!

Friendship and Natural Selection“More than any other species, humans form social ties to individuals who are neither kin nor mates, and these ties tend to be with similar people. Here, we show that this similarity extends to genotypes. Across the whole genome, friends’ genotypes at the SNP level tend to be positively correlated (homophilic); however, certain genotypes are negatively correlated (heterophilic). A focused gene set analysis suggests that some of the overall correlation can be explained by specific systems; for example, an olfactory gene set is homophilic and an immune system gene set is heterophilic.” – via charles!

Darkness in Anthropology: A Conversation with Napoleon Chagnon“Probably the single most anthropologically unacceptable thing I did was to take ‘biology’ seriously…. I began using commonly known ways to ‘measure’ relatedness between organisms — Sewall Wright’s coefficient of inbreeding and its extended concept, the coefficient of relatedness. This was very unusual in cultural anthropology. In short, I was discussing Yanomamö kinship with *the biological meaning* of kinship in mind — at a time when the vast majority of cultural anthropologists assumed that ‘kinship’ and ‘the biological meaning of Yanomamö kinship’ were, at best, only vaguely similar and any allusion to this was generally ‘suspect.’ But since ‘kinship’ was traditionally a central focus of anthropological theory, I began developing ways to show precisely, using my meticulous genealogies on the Yanomamö, that people took sides in fights according to how closely *genetically* they were related to each other and fought against people they were *less related to genetically*. Many of the most prominent anthropologists held the extreme view that ‘kinship’ among humans had *nothing* to do with the biological meaning of kinship as is assumed in the fields of biology, genetics, or animal husbandry. A common claim was something to the effect that ‘whatever kinship among humans was about, it was NOT about biology.'” – h/t g-nice!

Penn Biologists Show That Generosity Leads to Evolutionary Success – stewart and plotkin “examined the outcome of the Prisoner’s Dilemma as played repeatedly by a large, evolving population of players. While other researchers have previously suggested that cooperative strategies can be successful in such a scenario, Stewart and Plotkin offer mathematical proof that the *only* strategies that succeed in the long term are generous ones.”

Can Libya Be Saved?

“Two years ago this month, Tripoli, the capital of Libya, fell to the amalgam of rebel forces that had been closing in on the city. The country’s leader Muammar Qaddafi fled to his home town, Surt, where, on October 20, 2011, rebels stabbed, beat, and shot him to death after his convoy was hit by a NATO missile strike. Qaddafi’s eccentric, forty-two-year dictatorship was over, signalling the apparent end to a dramatic chain of events that had started nine months earlier, in the eastern city of Benghazi. There, inspired by the overthrow of Hosni Mubarak, in neighboring Egypt, Libyans had demonstrated against Qaddafi’s rule, and the protests had turned into a bloody national showdown with security forces. The protesters, eventually assisted by French, American, and British bombers under the NATO banner, succeeded. The smoke had not yet cleared when the victory was being touted as a shining example of what Western powers could do on a modern battleground without ever putting ‘boots on the ground.’

With no further need for war and with Western powers fussing over what was being vaunted as the oil-rich nation’s new democracy, Libya should have once again achieved peace and stability. Instead, the country, of more than six million people, seems to have been fatally destabilized by the war to remove its dictator, and it is increasingly out of control. Militias that arose on various regional battlefronts found themselves in possession of vast arsenals and large swaths of territory. Despite the orchestration of parliamentary elections and the assumption of nominal rule by civilian politicians in Tripoli, those militias have not stood down; instead, they have used their force and their firepower to try to effect change in the capital, even, on several occasions, besieging government buildings. They have also fought one another over long-held regional enmities; the most recent such battle occurred last month….

i’m just soooo glad we helped to bring democracy to egypt and libya — especially since they wanted it so much. so how’s all that working out for us anyway?:

“US official dies in Libya consulate attack in Benghazi”

“An American has been killed and at least one other wounded after militiamen stormed the US consulate in the Libyan city of Benghazi, officials say.

“It is believed the protest was held over a US-produced film that is said to be insulting to the Prophet Muhammad.

“The building was set on fire after armed men raided the compound with grenades.

“Protests have also been held at the US embassy in the Egyptian capital, Cairo.

“In the attack in Benghazi, unidentified armed men stormed the grounds, shooting at buildings and throwing handmade bombs into the compound.

“Security forces returned fire but Libyan officials say they were overwhelmed….

“The film that sparked the demonstration is said to have been produced by a 52-year-old US citizen from California named Sam Bacile, and promoted by an expatriate Egyptian Copt….

“‘Abuse freedom of speech’

“Thousands of protesters had gathered outside the US embassy in the Egyptian capital.

“Egyptian protesters condemned what they said was the humiliation of the Prophet of Islam under the pretext of freedom of speech…..”

you know, they just have to get over it. they don’t like freedom of speech and they don’t want it in their countries? — fine. but we have it in ours and they’re just gonna have to deal with it.

and we’d better not apologize for any of this, either! oh, wait. too late:

“The US embassy earlier issued a statement condemning ‘the continuing efforts by misguided individuals to hurt the religious feelings of Muslims – as we condemn efforts to offend believers of all religions’.”

sheesh.

“The first ever National Survey of Libya suggests that the population would still prefer one-man-rule over alternatives like democracy. The publication of the survey of over 2,000 Libyan people coincides with the anniversary of the first protests triggered by rebel forces against Gaddafi, which ended after months of fighting when he was killed in October 2011. Despite the widespread hatred of the Gaddafi regime, this survey of public opinion reveals that in five years’ time 35 percent would still like a strong leader or leaders for the country. Only 29 percent of those surveyed said they would prefer to live in a democracy….”

democracy-in-libya schedule

a couple of political scientists writing in foreign affairs think that libya shouldn’t rush into democracy — that the nation might not be quite ready for it yet. i gotta say that i agree with them:

“For democracy to take hold, a country needs parties and civic organizations that bridge traditional divides.”

absolutely!

“[P]ost-electoral violence is significantly less likely when the country has had a chance to build up impartial, rule-based, and non-corrupt institutions, including courts, police, and other governmental bureaucracies. It is generally better to wait to hold elections until administrative institutions are strengthened, as measured by the bureaucracy’s level of expertise, its autonomy from political pressure, and the professionalization of recruitment and training methods.”

hear, hear!

but the u.n. has crazy other plans:

“An internal UN document, meanwhile, envisions a two-stage transition to democracy in Libya. The first would be a loosely specified period of time during which ‘political preconditions’ for elections — establishing public security, building public trust in the impartiality of police, and electing a Provisional National Council within six to nine months to write a constitution — would be satisfied. That would be followed by a six-month period during which the NTC would set up Libya’s new electoral machinery, with help from the United Nations.”

well, unless that “loosely specified period of time” is about … oh, say … 1000 years — AND involves libyans not inbreeding anymore, then yeah — i’d say the u.n. plan is a winner!

maybe — maybe — the libyans would be ready for some local elections (town councils, pta representatives) in about 500 years, but for national elections, i’d guesstimate 1000. Forty generations of outbreeding? sounds about right.

libya update

been a while since i checked on events in libya. so, how are the rebel alliance those democracy-loving freedom fighters doing in libya, anyway?:

“Libyan rebel leader is killed, and tribal fissures emerge”

ruh roh.

“The top rebel military commander in Libya was killed yesterday [july 28th], and members of his tribe greeted the announcement with gunfire and angry threats. The violent outburst stirred fears that a tribal feud could divide the forces struggling to topple the Libyan dictator, Moammar Khadafy.

“The leader of the rebels’ provisional government, Mustapha Abdul Jalil, announced yesterday evening that assassins killed the commander, General Abdul Fattah Younes, and two other officers. But he provided few details.

“Younes, a former officer and Cabinet member in the Khadafy government, had long been a contentious figure among the rebels, some of whom doubted his loyalty. He had been summoned to Benghazi for questioning by a panel of judges, and members of his tribe – the Obeidi, one of the largest tribes in the east – evidently blamed the rebel leadership for having some role in the general’s death.

The specter of a violent tribal conflict within the rebel ranks touches on a central fear of the Western nations backing the Libyan insurrection: that the rebels’ democratic goals could give way to a tribal civil war over Libya’s oil resources….”

see also: “Assassination of Libya’s rebel military leader brings tribal divisions to forefront”“The murky death of Gen. Abdul Fateh Younes, who led Libya’s rebel forces, has called into question rebels’ ability to transcend tribal divisions and their credibility to lead a democratic transition.”
