Your Ancestors, Your Fate“The notion of genetic transmission of ‘social competence’ — some mysterious mix of drive and ability — may unsettle us. But studies of adoption, in some ways the most dramatic of social interventions, support this view. A number of studies of adopted children in the United States and Nordic countries show convincingly that their life chances are more strongly predicted from their biological parents than their adoptive families. In America, for example, the I.Q. of adopted children correlates with their adoptive parents’ when they are young, but the correlation is close to zero by adulthood. There is a low correlation between the incomes and educational attainment of adopted children and those of their adoptive parents. These studies, along with studies of correlations across various types of siblings (identical twins, fraternal twins, half siblings) suggest that genetics is the main carrier of social status.” – from gregory clark. see also The Son Also Rises: Surnames and the History of Social Mobility.

Reductionism! Determinism! Straw-man-ism!” The main problem, it seems to me, is a fundamental misunderstanding of what genetics as a science studies and how it relates to the function of complex systems. The following statements are not contradictory: 1. The function of a complex system emerges from the complex and dynamic interactions between all of the components of the system, in a context- and experience-dependent manner. 2. Variation in single components of the system (or in multiple components) can affect how it functions. Geneticists investigate the second question. Showing that variation in Gene X affects the behaviour or outcome of a system is not the same as saying that Gene X fully determines that behaviour or fully accounts for the entire system. Gene X is just a piece of DNA sitting in a cell somewhere – it doesn’t do anything by itself. But a *difference* in Gene X can account for a *difference* in how the system works. – from kevin mitchell.

There’s nothing wrong with looking for ‘gay genes’“The Left loves to tell the Right that it’s anti-science, pointing (not without reason) to the correlation between conservative beliefs and a failure to come to terms with the scientific facts of evolution and human-caused climate change. But there’s a subtler tendency on the Left; a fear of research into human nature, in case the findings are in some way politically uncomfortable.”

Scientists unlock a ‘microbial Pompeii’“An international team of researchers have discovered a ‘microbial Pompeii’ preserved on the teeth of skeletons around 1,000 years old.

The effect of paternal age on offspring intelligence and personality when controlling for paternal trait level [pdf] – “We examined the effect of father’s age at birth on offspring intelligence, head circumference and personality traits. Using the Minnesota Twin Family Study sample we tested paternal age effects while controlling for parents’ trait levels measured with the same precision as offspring’s. From evolutionary genetic considerations we predicted a negative effect of paternal age on offspring intelligence, but not on other traits. Controlling for parental intelligence (IQ) had the effect of turning an initially positive association non-significantly negative. We found paternal age effects on offspring IQ and Multidimensional Personality Questionnaire Absorption, but they were not robustly significant, nor replicable with additional covariates. No other noteworthy effects were found.” – from lars penke.

Reversed hierarchy in the brain for general and specific cognitive abilities: A morphometric analysis“Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g)…. The key finding reveals substantial variability in gray matter correlates at the test level, which is substantially reduced for the first-order and the higher-order factors. This supports a reversed hierarchy in the brain with respect to cognitive abilities at different psychometric levels: the greater the generality, the smaller the number of relevant gray matter clusters accounting for individual differences in intelligent performance.” – h/t ben southwood!

A nice bunch of flowers“The general factor of intelligence is strongest at lower levels of intelligence. It may be a case of ‘All neurones to the pump’. When abilities are low, most problems are difficult. In such cases, all resources have to be thrown at the problem. When abilities are higher there is more spare capacity for differentiation of abilities. Brighter persons have a lower proportion of their abilities accounted for by a common factor, even though the have higher absolute abilities.” – from dr. james thompson.

Four Lame Responses to Sam Harris’ Moral Landscape Challenge“Moral emotions, like every other evolved trait, exist because their presence increased the probability that the genes responsible for the existence of those traits would survive and reproduce.

Free will beliefs and motivation to punish“In a paper forthcoming in the Journal of Personality and Social Psychology, Cory J. Clark and co-authors provide evidence that widespread belief in the existence of free will is bolstered by a fundamental desire to punish wrongdoers…. As Clark et al. put it, ‘There seems little doubt that the subjective experience of choosing and acting supports people’s belief in free will, but our findings suggest another powerful motivating factor: the human impulse to blame and punish. People believe in free will – at least in part – because they wish to affirm that people who do immoral things could have and should have acted differently’.”

Creativity and personality in classical, jazz and folk musicians“[J]azz musicians are more frequently engaged in extracurricular musical activities, and also complete a higher number of creative musical achievements. Additionally, jazz musicians show higher ideational creativity as measured by divergent thinking tasks, and tend to be more open to new experiences than classical musicians. This study provides first empirical evidence that jazz musicians show particularly high creativity with respect to domain-specific musical accomplishments but also in terms of domain-general indicators of divergent thinking ability that may be relevant for musical improvisation.” – h/t mary louise cowan!

Migration and interaction in a contact zone: mtDNA variation among Bantu-speakers in southern Africa“In this study, we analyze complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the Bantu expansion. Our results show that most of these Bantu-speaking populations are genetically very homogenous, with no genetic division between speakers of Eastern and Western Bantu languages. Most of the mtDNA diversity in our dataset is due to different degrees of admixture with autochthonous populations.”

Silver Blaze“[I]n most parts of Europe, it looks as if modern populations inherited the three EEF/WHG/ANE groups (Levantine farmers, West Hunters and Sibermen) via only two proximate ancestral populations. Europe at the time was almost entirely occupied by Sardinian-like farmers – then another population moved in, one that had about 3 times as much West Hunter as Sibermen.” – from greg cochran.

Replacement or continuity?“Ancient DNA seems to promise a clearer picture because the only source of uncertainty is the age of the skeletal material. Unfortunately, this new method is more sensitive to uncertainty from another source: natural selection. Late hunter-gatherers and early farmers had to adapt to different environments. There certainly was a genetic divide between the two, but did it result from differences in origin or from differences in natural selection?” – from peter frost.

(note: comments do not require an email. rust cohle for president!)

as some of you already know, and many of you may have guessed from my atrocious writing style, i have some language difficulties — me and words don’t really get on.

i mentioned before in a comment that i don’t think in words — at least i don’t experience my thinking as happening in words. i think in pictures. well, that’s what i tell people in order to keep it simple. it’s more complicated than that. what i really think in is sort of amorphous blobby things which sometimes seem almost solid enough that i could reach out and touch them, but most of the time they are just blobby things in my mind’s eye.

the best description of this experience that i’ve ever seen is from galton who was describing how he thought. from his “Thought without Words” [opens pdf]:

“Prof. Max Muller says that no one can think of a dog without mentally using the word dog, or its equivalent in some other language, and he offers this as a crucial test of the truth of his theory. It utterly fails with me. On thinking of a dog, the name at once disappears, and I find myself mentally in that same expectant attitude in which I should be if I were told that a dog was in an obscure part of the room or just coming round the corner. I have no clear visual image of a dog, but the sense of an ill-defined spot that might shape itself into any specified form of dog, and that might jump, fawn, snarl, bark, or do anything else that a dog might do, but nothing else….

“It is a serious drawback to me in writing, and still more in explaining myself, that I do not so easliy think in words as otherwise. It often happens that after being hard at work, and having arrived at results that are perfectly clear and satisfactory to myself, when I try to express them in language I feel that I must begin by putting myself upon quite another intellectual plane. I have to translate my thoughts into a language that does not run very evenly with them. I therefore waste a vast deal of time in seeking for appropriate words and phrases, and am conscious, when required to speak on a sudden, of being often very obscure through mere verbal maladroitness, and not through want of clearness or perception.”

me and galton. i don’t feel so bad. (^_^)

yes, so, most of the time when i think, it’s in these amorphous shapes — “ill-defined spot[s] that might shape [themselves] into any specified form[s]“ of whatever i happen to be thinking about. and, yes — i spend all day, every day translating my thoughts into words! when i need to commicate to someone else, that is. exhausting, lemme tell you.

however, when i get tired, especially really tired, then i do start to think in actual pictures. if i were to think of a dog when i was tired, i would definitely see a clear image of a dog in my mind’s eye. the more tired i get, the more “real” the image becomes — i.e. the more i see it in my visual field rather than just in my mind’s eye. another way of putting it would be that the image becomes sharper — more in focus. the pictures never completely take over my visual field, though. the images are always semitransparent. but, when i’m really, really exhausted, and then lie down to sleep, then i experience an uncontrollable, usually rapid fire, slide show in my head (visual field if i open my eyes). which is pretty cool! i enjoy those! (^_^)

the well known high-functioning autist temple grandin has said that she experiences thinking as a sort of video stream. my experience is not that extreme — most of the day i have galton’s “ill-defined” shapes, which then become more clearly defined pictures in my mind’s eye the more tired i get, until eventually they start to invade my vision (always in a semi-transparent way).

i should mention here that speech also becomes much more of a challenge as the day goes on. and, again, once i’m exhausted, i start to sound like i’ve had one too many gin and tonics. (~_^) i don’t slur my words, it just becomes next to impossible to fetch the words out of wherever they normally hide in my skull. (~_^)

oftentimes, more abstract concepts — like “freedom” or “democracy” or “corruption” — appear in my mind’s eye when i start to get tired (i.e. past whatever point it is that the “ill-defined” shapes start to be replaced by pictures) as printed words. presumably it’s hard for my brain to come up with an image for “freedom,” so i just see “freedom” written out like the words in one of those fridge magnet poem sets. and, yes, now that i think of it, the words are always in lowercase! the font is something plain, like arial. just black font. no colors. again, these are words that i see in my mind’s eye which are representing thoughts that i am having, normally when i start to be a bit tired — toward the end of the day.

so far none of this is synesthesia (afaik). the synesthesia that i think i might have — and it’s a mild form, if it’s synesthesia at all — is something called ticker tape synesthesia. i’d never heard of it before the other day until kevin mitchell tweeted about it. from this abstract:

“Ticker tape is the automatic visualization of spoken words or thoughts, such as a teleprompter. For example, when spoken to, a ticker taper might see mentally the spoken words displayed in front of his face or as coming out of the speaker’s mouth.”

cool! (^_^)

just like i don’t experience temple grandin-style videos when thinking, i don’t have full ticker tapes. BUT i do have either blobs or pictures or words pop up when i listen to other people speaking — again, it moves from blobs to pictures/”printed” words the more tired i get. when i’m quite tired, then i start to see the occasional word (maybe one or two per sentence?) that the other person is speaking pop up in my visual field (although like the pictures, the words are also semitransparent). they don’t ticker tape out of the person’s mouth, though, and it’s not like subtitles either. i just see the words appear and then disappear right in front of wherever i happen to be looking — so it could be in front of the person’s face if i’m looking right at them, but it could be anywhere i happen to be looking. on the other hand, i might just as easily see a picture instead of “printed” word.

i have, i think, another form of synesthesia, too! — spatial sequence synesthesia:

“With spatial sequence synesthesia (SSS), people tend to see numerical sequences as points in space. For instance, the number 1 might be farther away and the number 2 might be closer. People with SSS may have superior memories; in one study they were able to recall past events and memories far better, and in far greater detail than those without the condition. They also see months, or dates in the space around them. Some people even see time like a clock above and around them.”

i have a terrible memory as far as recalling events goes, but, yes, the days of the week and the months all have a “place” — they’re arranged in a semi-circle just above and in front of my head. i “look” at them when i want to remember if wednesday is before or after tuesday. (yeah, i know — weird.) and it feels like i could reach out and grab hold of them. (don’t worry — i don’t! i know they’re not really there.) a lot of concepts or ideas that i have also have locations — i don’t know if this is synesthesia or not. my favorite topics of inbreeding and outbreeding and manorialism, for instance: inbreeding is over here on the left (above my head, again, and a bit in front), outbreeding is on the right (above and in front), and manorialism is right above me. don’t ask me why!

so, my brain is definitely wired funny!

some other conditions that i’ve got that (strongly!) hint at faulty wiring in my brain:

- visual snow: have always had, even as a kid. it’s stationary (thank, goodness!), so it’s not distracting. only notice it if i look at a plain colored background, like a clear blue sky.
- tinnitus: again have always had, even as a kid. i’ve got a rather high pitched ringing that i don’t pay attention to unless it’s really quiet (like going to bed at night).
- prosopagnosia: face blindness. have a mild version of it. i recognize people that i know well that i see all the time (including myself!), but someone who is only an acquaintance, if i meet them “out of context” (like not at work where maybe i know them from), then…heh…hilarity usually ensues. i won’t bore you with stories, but i’ve got some funny (embarassing!) ones. (*^_^*)
- asperger’s: not officially diagnosed, but i pass simon baron-cohen’s tests with flying colors. if i don’t have asperger’s, then there’s something really wrong with me! (~_^)

so, i seem to have mild forms of all these things: autism (asperger’s), visual snow (stationary), tinnitus (background ringing that’s easy to ignore), prosopagnosia (mild face blindness), thinking in “pictures” (but the actual pictures only happen when i’m tired), ticker tape synesthesia (not full ticker tape, just some words here and there when i’m tired), and spatial sequence synesthesia (days of the week, some concepts).

but enough about me. (*^_^*)

Life on Earth may have developed below rather than above ground, reveal scientists“Scientists have now discovered microbes living and reproducing as deep as 5km (3.1 miles) below ground and studies have shown that they are likely to have survived in complete isolation from the surface biosphere for millions and perhaps even billions of years. One of the latest studies into the deep biosphere has found that these microbes form a distinct subsurface community of genetically similar individuals despite living on opposite sides of the world. This global similarity of such an isolated life-form suggests that they may have evolved directly from a common ancestor that lived as long ago at the period when life on earth originated, some 3.5 billion years ago.”

Scientists discover double meaning in genetic code“[G]enomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled.

Environment drives genetic changes in Evolution Canyon“[R]esearchers with the Virginia Bioinformatics Institute at Virginia Tech studying fruit flies that live on opposite slopes of a unique natural environment known as ‘Evolution Canyon’ show that even with migration, cross-breeding, and sometimes the obliteration of the populations, the driving force in the gene pool is largely the environment.” – see also Genome differentiation of Drosophila melanogaster from a microclimate contrast in Evolution Canyon, Israel.

Big brains are all in the genes“Scientists have moved a step closer to understanding genetic changes that permitted humans and other mammals to develop such big brains…. Dr Humberto Gutierrez, from the School of Life Sciences, University of Lincoln, UK, led research which examined the genomes of 39 species of mammals with the aim of better understanding how brains became larger and more complex in mammals…. The researchers found a clear link between increased brain size and the expansion of gene families related to certain biological functions.”

Western scrub-jays allocate longer observation time to more valuable information“When humans mentally reconstruct past events and imagine future scenarios, their subjective experience of mentally time travelling is accompanied by the awareness of doing so. Despite recent popularity of studying episodic memory in animals, such phenomenological consciousness has been extremely difficult to demonstrate…. Thus, the jays can collect information to solve a future problem. Moreover, they can differentiate sources of information according to their potential value and modify behaviour to efficiently collect important, usable information. This is the first evidence of metacognition in a species that passes the behavioural criteria for both retrospective and prospective mental time travel.”

The island itself offered protection from other hungry predators, and raw materials such as wood and stone for fashioning tools would have been abundant.”

Older Dads: Possible Links to Autism, Schizophrenia in Offspring – inherited epigenetic effects? – “Maria Milekic, PhD, reported today, at the American College of Neuropsychopharmacology annual meeting in Hollywood, Florida, that old mice have an epigenetic change ‒ a loss of DNA methylation at the locations where the genetic code starts being transcribed. DNA methylation is a biochemical process that plays an important regulatory role in development and disease. The work was done by a research team in the Department of Psychiatry at Columbia University. Offspring of old fathers showed the same deficit in DNA methylation, and they differed in their behavior from the offspring of the young fathers.”

Genetics accounts for more than half of variation in exam results @the guardian – “[T]he authors point out that genetics emerges as such a strong influence on exam scores because the schooling system aims to give all children the same education. The more school and other factors are made equal, the more genetic differences come to the fore in children’s performance. The same situation would happen if everyone had a healthy diet: differences in bodyweight would be more down to genetic variation, instead of being dominated by lifestyle.” – see also Nature more than nurture determines exam success @newscientist – “Overall, across the three core subjects of English, mathematics and science, achievement was 58 per cent determined by genetics. Individually, achievement was 52 per cent down to genetics for English, 55 per cent for maths and 58 per cent for science. The figure for humanities was lower at 42 per cent. This was a surprise to Plomin because, traditionally, excellence in humanities subjects such as art or music is considered to be ‘handed down’ from parents, whereas science is considered a product of the teaching environment.” – see also The genetics route could spell a new direction for education @the independent – “[I]t may be that the innate differences in children’s abilities because of their genes could argue the case for a more tailor-made individual curriculum to offset the disadvantages of birth.” – no sh*t! – see also New twin study by Plomin, Shakeshaft et al from steve sailer – see also Strong Genetic Influence on a UK Nationwide Test of Educational Achievement at the End of Compulsory Education at Age 16.

Dr Ian Frampton, an Exeter University psychologist, stressed the researchers still had more work to do, but said they may have hit upon something significant…. Professor Michael Depledge of Exeter University, a former Environment Agency chief scientist, said urban dwellers could be suffering in the same way as animals kept in captivity. He said the move to the cities had been accompanied by an ‘incredible rise in depression and behavioural abnormalities’.” – h/t ed west!

Diet rapidly and reproducibly alters the human gut microbiome“[S]hort-term consumption of diets composed entirely of animal or plant products alters microbial community structure and overwhelms inter-individual differences in microbial gene expression. The animal-based diet increased the abundance of bile-tolerant microorganisms (Alistipes, Bilophila and Bacteroides) and decreased the levels of Firmicutes that metabolize dietary plant polysaccharides (Roseburia, Eubacterium rectale and Ruminococcus bromii). Microbial activity mirrored differences between herbivorous and carnivorous mammals, reflecting trade-offs between carbohydrate and protein fermentation. Foodborne microbes from both diets transiently colonized the gut, including bacteria, fungi and even viruses. Finally, increases in the abundance and activity of Bilophila wadsworthia on the animal-based diet support a link between dietary fat, bile acids and the outgrowth of microorganisms capable of triggering inflammatory bowel disease. In concert, these results demonstrate that the gut microbiome can rapidly respond to altered diet, potentially facilitating the diversity of human dietary lifestyles.”

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.

“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.’”

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?

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.
