Crickets in two places fall silent to survive“To hide themselves from deadly flies, crickets on two Hawaiian islands have evolved an inability to sing. Ten years ago, two years apart, males appeared on Kauai and Oahu with altered wings, which they would normally rub together to chirp and attract females. New findings published in the journal Current Biology show that the wing changes are physically different and arose from separate mutations. This makes the silent crickets a brand new example of ‘convergent evolution’.” – and some really rapid evolution!

Microbes May Drive Evolution of New Animal Species“[S]ymbiosis — a long-term, stable and often beneficial interaction between organisms — could drive two populations apart, the first step in the development of new species. Although the idea has been floating around for nearly a century, it has only recently begun to gain traction in biology. This idea contrasts sharply with the traditional picture of evolution, in which new species emerge either from geological isolation or from a relentless struggle for food and mates. According to this new hypothesis, a host organism’s microbes might trigger changes in mating and reproduction that begin to define two different populations.” – h/t charles!

you gotta read this!: Coincidental Killers“We assume that microbes evolved to attack humans when actually we are just civilian casualties in a much older war…. Many of the pathogens we fear most are mere tourists on the human body. Their real homes are oceans, caves, or soils. To understand them, we need to understand them within their natural ecology. Soil, for example, is an extreme habitat for a microbe: harsh and constantly changing. It can quickly oscillate from flood to drought, from scalding heat to freezing cold, and total darkness to intense solar radiation. It’s rife with other competing microbes, and crawling with hungry predators. We fear lions and tigers and bears; bacteria have to contend with phage viruses, nematode worms, and predatory amoebas. All of these conditions can lead to adaptations that make microbes accidentally suited for life in a human host. We are, after all, just another environment. A thick capsule that shields a microbe from dehydration could also shield it from our immune system. A spore that is adapted for travelling through the air can be easily inhaled into a respiratory tract.”

Genetically identical ants help unlock the secrets of larval fate“A young animal’s genes are not the only genes that determine its fate. The genetic identity of its caretakers matters too…. [A] team led by Serafino Teseo of the University of Paris 13 used the unique aspects of the [clonal] ants’ biology to test the indirect role genes play in shaping the future identity of larvae and whole colonies by looking at the interaction between larvae and adults. They did so by observing the success of two ant clones, A and B, in pure colonies or mixed together into chimeric colonies. They also swapped broods, so A adults raised B larvae and vice versa. It turned out that A and B larvae developed differently depending on whether A or B nurses raised them. Left alone, pure A colonies produced the most young after six generations, making them more successful than B. However, in mixed colonies, B did better because its larvae more frequently turned into large adults that specialize in egg-laying rather than smaller, foraging-focused individuals….” – h/t rolf muertter!

Mitochondrial DNA of first Near Eastern farmers is sequenced for the first time“According to conclusions, genetic affinities have been observed between the mitochondrial DNA of first Neolithic populations and the DNA of first Catalan and German farmers. This suggests that probably Neolithic expansion took place through pioneer migrations of small groups of population. Moreover, the two main migration routes — Mediterranean and European — might have been genetically linked. ‘The most significant conclusion — highlights Eva Fernández — is that the degree of genetic similarity between the populations of the Fertile Crescent and the ones of Cyprus an Crete supports the hypothesis that Neolithic spread in Europe took place through pioneer seafaring colonization, not through a land-mediated expansion through Anatolia, as it was thought until now….’ Other scientific studies had already provided signs of an alternative scenario of Neolithic spread in Europe different from the one through Anatolia. According to Turbón, ‘recent archaeological finds have proved that the Neolithic arrived to Cyprus around 10,600 years ago, some years after the first documentation of agricultural practices in the Near East.’ Architecture and burial models found in Cyprus’ sites are similar to the ones found in the Middle Euphrates basin, ‘that indicates a direct colonisation of these territories,’ highlights the author. ‘Besides, spatial interpolation of radiocarbon dates from different Neolithic sites in the Near East and Europe also suggests a first seafaring expansion through Cyprus,’ he concludes.” – orginal research article.

A twist in Austronesian origins“The Taiwanese origin of Austronesians is widely accepted. A new preprint confirms this theory, but adds a new twist to the story of Austronesian dispersals, as it seems that in their western expansion, Austronesians picked up some Austroasiatic ancestry. This means either that Austroasiatic speakers preceded them in islands where Austronesian languages are now spoken, or that the Austronesians picked up this kind of ancestry in the mainland before settling in the islands.” – from dienekes.

A new allele for blond hair“There is a widespread belief that whatever made Europeans fair-skinned also gave them their unique palette of hair and eye colors.

A Genetic Map of Fireworks in Time“French Canadians and Slavs are both cases of populations which were once relatively modest and began in a narrow delimited region, but now are quite expansive and numerous. In the case of the East Slavs the demographic expansion also entailed the absorption of numerous Uralic tribes, as well as later Turks. And this illustrates one of the major details which I think has characterized the genetic turnover of human populations: phase shifts from a relatively static one defined by isolation by distance gene flow across clinal gradiants, to a rapid expansion of a small subset, and the overlay of this component as a palimpsest over the underlying variation. In some cases the replacement is nearly total, as in the modern United States. In other cases, as among Great Russians, the Slavic affinities of this population, and its association with Poles and other groups are clear, but there was a non-trivial uptake of exogenous segments which might allow for a reconstruction of the prior genetic landscape. These changes occur over short periods, and are bright fireworks against the comparatively static firmament.” – from razib.

Male faces ‘buttressed against punches’ by evolution“A new theory suggests that our male ancestors evolved beefy facial features as a defence against fist fights. The bones most commonly broken in human punch-ups also gained the most strength in early “hominin” evolution.

Faster eye responses in Chinese people not down to culture“New research from University of Liverpool scientists has cast doubt on the theory that neurological behaviour is a product of culture in people of Chinese origin. Scientists tested three groups – students from mainland China, British people with Chinese parents and white British people – to see how quickly their eyes reacted to dots appearing in the periphery of their vision…. The findings, published in the journal PLoS One, revealed that similar numbers of the British Chinese and mainland Chinese participants made high numbers express saccades, with the white British participants made far fewer. Culturally the British Chinese participants were similar to their white British counterparts and different to the mainland Chinese students.”

New genes involved in food preferences will revolutionize diets and improve health“The researchers undertook genome wide association studies (GWAS) to try to unravel the genetic basis for certain food preferences. 2311 Italian subjects participated in the discovery step, while 1755 from other European countries and from Central Asia were used in order to further verify the findings. They uncovered 17 independent genes related to liking for certain foods, including artichokes, bacon, coffee, chicory, dark chocolate, blue cheese, ice cream, liver, oil or butter on bread, orange juice, plain yoghurt, white wine and mushrooms. Surprisingly, none of the genes thus identified belonged to the category of taste or smell receptors…. In a second study, the researchers amassed the response of around 900 healthy adults from North Eastern Italy to salt, and related this to a DNA sequence variation found on the KCNA5 gene, known to be related to taste pathways in mammals.”

First direct evidence for human sex pheromones“‘By using dynamic point-light displays that portray the gaits of walkers whose gender is digitally morphed from male to female, we show that smelling androstadienone systematically biases heterosexual females, but not males, toward perceiving the walkers as more masculine. By contrast, smelling estratetraenol systematically biases heterosexual males, but not females, toward perceiving the walkers as more feminine. Homosexual males exhibit a response pattern akin to that of heterosexual females, whereas bisexual or homosexual females fall in between heterosexual males and females. These effects are obtained despite that the olfactory stimuli are not explicitly discriminable. The results provide the first direct evidence that the two human steroids communicate opposite gender information that is differentially effective to the two sex groups based on their sexual orientation.'” – @deric bownds’ mindblog.

Genetic relatedness predicts contact frequencies with siblings, nieces and nephews: Results from the Generational Transmissions in Finland surveys“Individuals have more contacts with full than with half siblings.

Beware Armchair Psychoanalysis“‘Behavioral genetic studies have proved beyond a shadow of a doubt that heredity is responsible for a sizable portion of the variations in people’s personalities. Some people are more hot-tempered or outgoing or meticulous than others, and these variations are a function of the genes they were born with as well as the experiences they had after they were born. The exact proportion— how much is due to the genes, how much to the experiences—is not important; the point is that heredity cannot be ignored.'” – from jayman (quoting judith rich harris there).

SD-IE and other differentiation effects in Italy and Spain [pdf] – “SD–IE [strategic differentiation–integration effort] is a strategic differentiation effect present amongst indices of life history (LH), such that persons and populations of slow LH are more differentiated compared to those of fast LH. We found that this phenomenon is present amongst provinces in Italy and Spain, similarly to demonstrations among US states and Japanese prefectures. The average effect size of SD–IE was found to be bigger in Spain and Italy….. In the present study, we test SD–IE using regional-level data for counties in Spain and Italy.”

Is the smart fraction as valuable as previously thought?“‘Consistent with the intellectual class theory advocated by Rindermann and Thompson (2011) and Rindermann et al. (2009), our research findings showed strong evidence that those people that have high IQ are the most relevant influence on economic development. Although our results suggested that all three examined IQ categories promote higher economic growth, the intellectual class has the highest impact followed by the mean ability and non-intellectual classifications. Similarly, the intellectual class also has a highly significant effect on generating technological progress, whereas the influence of the other two groups is immaterial.'” – @dr. james thompson’s blog.

if you discovered your friend’s wife in bed with another man in thirteenth century england, you’d tell your friend, right? [edit: and/or conclude that one or more of you must be a time lord(s)!] how to tell him though? hmmmm. email? text? nooooo. send him a letter! yeah, send him a letter.

it would’ve been an awkward sorta letter to write, though, but you know what? there was a form letter for the occasion! i know! who knew that they even had form letters in the 1200s?! but they did! and they were kept in collections called formularies, some of which are still hanging around in archives like at the british museum.

here from Lost Letters of Medieval Life: English Society, 1200-1250 [pg. 222 – link added by me]:

“A Man Warns His Friend that He Has Seen the Latter’s Wife Naked in Bed with Another Man, and Sends Her Girdle [no, not one of these, one of these – h.chick] as Evidence

“F. tells G. that he has seen another man in bed with G.’s wife

“To his beloved friend A., B. sends greetings. Except that I believed it would offend you, I would reveal something that I lately saw. But because it is wicked to conceal wickedness, I prefer to disclose [it] rather than to have the odium of the heavenly realm. For I saw your wife in R.’s bed, the two of them alone and naked together. And so that she cannot deny it, I took her girdle [i.e., belt] as a token, which I send to you, and the sight of it should serve you as evidence of this misdeed. You should see to it that she is punished, together with him. Farewell.”

so there you go.

the editors of Lost Letters reckon that this form letter was composed a bit tongue-in-cheek, but still with a serious lesson in mind [links added by me]:

“At first sight, this would seem to be an odd candidate for inclusion in a collection of model letters, since the compiler is unlikely to have assumed that there was a need for a form letter in which one friend notified another of the adultery of the latter’s wife. It seems likely that this letter was included in the collection for somewhat different reasons. First, it may have been intended, at least in part, for the amusement of the business students and other male readers for whom the formulary was primarily designed. In a similar fashion John of Garlande included some smutty material in his ‘Dictionarius’, a contemporary treatise designed to teach Latin vocabulary but written primarily in the form of a walking tour of Paris. Second, and more seriously, this letter may have been included to remind readers that, if they ever made a serious accusation against another person in writing, they had better have solid evidence — such as the wife’s girdle, in this case — to support their allegation.”

in anglo-saxon england/the early medieval period, you could just kill a guy if you caught him sleeping with your wife, and everyone would be very understanding. by the 1200s, however, this course of action was no longer permitted [pg. 226 – link added by me]:

“Around 1215, Thomas of Chobham, a canon laywer and subdean of Salisbury, summarized the legal recourse available to an outraged husband, as he understood it: ‘It is worth noting that secular law once allowed a man to kill an adulterer found with his wife. This is no longer permitted, but only for him to cut off the man’s genitals so that he will never spawn another who will follow him in his vileness.‘”

so there was that possibility!

you had to keep your wife under control, though. if you didn’t, you couldn’t accuse her of adultery in the ecclesiastical courts or castrate anybody:

“[S]ince women were considered to be sexually voracious, and certain occupations, such as that of barmaid, exposed them to dangerous temptations, a husband who allowed his wife to work in a drinking-house was not permitted to press charges of adultery against her if she succumbed.

(~_^)

also:

“Canon lawyers also ruled that a wife who had been raped could not be charged with adultery….”

fair enough.

Ancient DNA Links Native Americans With Europe“…from the complete nuclear genome of a Siberian boy who died 24,000 years ago — the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today’s Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or western Asia. The finding suggests that about a third of the ancestry of today’s Native Americans can be traced to ‘western Eurasia,’ with the other two-thirds coming from eastern Asia…. It also implies that traces of European ancestry previously detected in modern Native Americans do not come solely from mixing with European colonists, as most scientists had assumed, but have much deeper roots.” — see also: The First of the Mohicans from greg cochran.

Your face may have been sculpted by junk DNA“There is a huge degree of variation in human faces but, as family resemblances show, the overall shape is heavily constrained by genetics. However, so far, geneticists have identified only a small number of genes that influence the shape. These explain just a tiny fraction of the variation seen in human faces. According to Axel Visel of the Lawrence Berkeley National Laboratory in California and his colleagues, more variation is controlled by distant-acting enhancers. These are short sequences of DNA, in non-coding regions of the genome, that can influence the activity of the facial genes, even if they are a long way along the DNA strand.”

Behavior problems in preschool and child care centers may be an issue of genes“A new study suggests that some children may be genetically predisposed to developing behavioral problems in child care and preschool settings…. [B]irth parents who had high rates of negative emotion and self-control, based on a self-reported temperament scale, were more likely to have children who struggled with behavioral issues such as lack of self-control and anger, in child care centers. They controlled for adoptive parent’s characteristics, and still found a modest effect based on the genetic link.”

Your Ethnicity Determines the Species of Bacteria That Live in Your Mouth“[P]eople from each of the four different ethnic groups represented in the study (all participants self-identified as either Caucasian, African-American, Chinese or Latino) generally had similar species of bacteria, especially underneath the gums. As a result, simply by counting which varieties of bacteria appeared in this area, the researchers developed a model that was able to guess a person’s ethnicity with an accuracy significantly better than chance — it got it right 62 percent of the time. Some groups were even easier to identify via the bacteria than others: It could correctly identify Latinos 67 percent of the time and African-Americans with 100 accuracy. The variation along ethnic lines, they believe, is a reflection of genetics, not environment. That’s because, if you assumed that the mouth microbiome is totally dependent on environmental factors, you’d expect that members of the same ethnic group would have different mixes of bacteria depending on whether they were first-generation immigrants to the U.S. or had family histories that stretched back generations in the country. Instead, people’s background — in terms of foods they ate and other lifestyle trends — didn’t seem to have any correlation with the bacterial communities in their mouths. – h/t super bob!

Herpes virus genome traces the ancient path of human migration“Researchers…sequenced the genomes of 31 samples of herpes simplex virus type-1 to reconstruct how it hitchhiked on humans as they dispersed around the world.

The analysis showed that African strains of the virus contained the most genetic diversity — suggesting that they had the oldest roots.”

Low historical rates of cuckoldry in a Western European human population traced by Y-chromosome and genealogical data“[W]e estimate that over the last few centuries, EPP rates in Flanders (Belgium) were only around 1–2% per generation. This figure is substantially lower than the 8–30% per generation reported in some behavioural studies on historical EPP rates, but comparable with the rates reported by other genetic studies of contemporary Western European populations. These results suggest that human EPP rates have not changed substantially during the last 400 years in Flanders and imply that legal genealogies rarely differ from the biological ones.” – h/t rob brooks!

Asymmetries in altruistic behavior during violent intergroup conflict“Some empirical studies on intergroup conflict in hunter-gatherer societies and chimpanzees indicate that fitness relevant risks and potential benefits of attacks and defenses might have differed substantially under ancestral conditions.

Analyzing detailed historical case data from 20th century wars, this study finds that altruistic behavior towards members of the in-group indeed seems to occur more frequently when soldiers are defending themselves and their comrades against enemy attacks.” – h/t hbd bibliography!

Genetic Variants Linked to Educational Attainment“A multi-national team of researchers has identified genetic markers that predict educational attainment by pooling data from more than 125,000 individuals in the United States, Australia, and 13 western European countries…. Combining the two million examined SNPs, the SSGAC researchers were able to explain about 2 percent of the variation in educational attainment across individuals, and anticipate that this figure will rise as larger samples become available.” – h/t friendly e-mailer!

GSS on Haidt’s Moral Foundations theory“The GSS results largely support Haidt’s divisions, with liberals putting greater emphasis on liberty/oppression and especially care/harm, just as he found to be the case.

Homosexuality is natural. Fine. But what if homophobia is natural, too?

The Ugly Truth About Obesity“So yes, the obese group is not unlike its negative stereotypes. Of the, ‘lazy’, ‘sloppy’, ‘less competent’, ‘lacking in self-discipline’, ‘disagreeable’, ‘less conscientious’, ‘poor role models’, ‘unintelligent’, ‘unsuccessful’, ‘weak-willed’, ‘unpleasant’, ‘overindulgent’, it seems ‘disagreeable’ and ‘unpleasant’ are the only clear misses. This is not to hate on the obese, but to call a spade a spade.” – from staffan!

Breeding the Nutrition Out of Our Food“Studies published within the past 15 years show that much of our produce is relatively low in phytonutrients, which are the compounds with the potential to reduce the risk of four of our modern scourges: cancer, cardiovascular disease, diabetes and dementia. The loss of these beneficial nutrients did not begin 50 or 100 years ago, as many assume. Unwittingly, we have been stripping phytonutrients from our diet since we stopped foraging for wild plants some 10,000 years ago and became farmers.”

“Oxford paedophile ring found guilty of grooming vulnerable underage girls for sexual exploitation”

“- Fighting broke out in the dock as two other defendants were cleared
– Seven men found guilty of catalogue of offences involving underage girl
– Verdicts delivered at Old Bailey at the end of a five month trial
– The seven men have been remanded in custody for sentencing next month
– Girls were so young ‘they had just stopped believing in the Easter bunny when they were corrupted’
Police identified as many as 22 girls who were ‘groomed, corrupted, brainwashed and abused and then sold for sex and worse’
– Two of the three care homes where victims of the Oxford sex ring lived have been closed down but only one member of staff was sacked

“Police and social workers apologised today for not protecting vulnerable schoolgirls who were sexually abused and exploited by a paedophile ring….”

bit late.

“The admissions of failure which saw the girls being drugged and raped when they were supposed to be in the care of the authorities came as seven men were found guilty of a catalogue of offences including rape, trafficking and organising prostitution over eight years involving girls as young as 11 in the Oxford area.

“In dramatic scenes, fighting broke out in the dock at the Old Bailey as two other defendants were cleared.

“Two sets of brothers, Akhtar Dogar, 32, and Anjum Dogar, 31, and Mohammed Karrar, 38, and Bassam Karrar, 33, were convicted along with Kamar Jamil, 27, Assad Hussain, 32, and Zeeshan Ahmed, 27….”

i wonder if there are any cousins in there, too?

“The girls targeted by the Oxford sex ring were so young ‘they had just stopped believing in the Easter bunny’ when they were ‘corrupted entirely’ by the extreme abuse, the retired lead detective said.

“He said that the seven predators who ran the organised child sex ring ‘identified the most vulnerable girls in our society and corrupted them entirely’.

“Simon Morton, who was then an acting Detective Chief Inspector, said he identified as many as 22 girls who were ‘groomed, corrupted, brainwashed and abused and then sold for sex and worse’ by the gang for ‘the best part of a decade.’

“However, the girls suffered from ‘Stockholm Syndrome’, gaining a bizarre trust in their captors, until his investigation was able to win them over and allow the girls to break their silence….

“The trial followed the jailing last year of Asian men in Rochdale for abusing vulnerable girls, another case where chances to stop the gang were missed….

“Police have arrested a further nine men from the Oxford area under Operation Bullfinch….”

Born to run: genetic test can reveal those best able to run marathons“[T]o run a marathon in a good time requires the right combination of genes and that nearly a fifth of the population lack this special mix. For runners with the right genes, it means their bodies can quickly adapt to carry large amounts of oxygen to their muscles, allowing them to run faster and for longer. Those who lack these genes, however, will never improve, no matter how much they train, and their performance may even get worse the harder they push themselves.”

the kinds of “grooming” and rape stories that i’ve posted about lately (here and here and here), in which gangs of (often related) immigrant men — muslim immigrant men — have been targeting underage girls, have all been summarized on this dedicated blog:

The Rape Jihad

the rape jihad is tracking all of the u.k. stories i’ve posted about — plus many, many more (i told you there were more…) — as well as similar stories from other countries (do i sense a pattern?).

i wish we didn’t need to have such a website, but sadly we do. i’m just glad that someone else has the stomach to report on all these cases, ’cause i sure don’t. =/

thank you, blogger.
