The Earliest Group Of Modern Humans To Branch Off Survived Until Just 2,300 Years Ago – h/t mr. robert ford!

Archaeologists unearth remains of oldest Norman ever found which ‘fills gap in our knowledge of pre-Neanderthal evolution’“On a bend of the river Seine near Rouen in Normandy, archaeologists have found the remains of the oldest Norman ever discovered. The three bones from the left arm of a pre-Neanderthal should shed fresh light on a little-known period. In particular, they could help scientists to understand the evolution of the squat, muscular hunters who died out 30,000 to 40,000 years ago, just after the first humans arrived in what is now Europe. The discovery of the bones at Tourville-la-Rivière, 14km south of Rouen, is exceptional because ‘this is a period with very few fossils’, according to Bruno Maureille, a palaeontologist at the National Centre for Scientific Research. He said the arm bones, dating from 200,000 years ago, in the Middle Pleistocene era, were ‘the only known example from northern Europe’.”

Europe the birthplace of art? Cave art shows Indonesia has a claim“Using this method, the researchers determined that one of the hand stencils they sampled was made at least 39,900 years ago and that a painting of an animal known as a pig deer was at least 35,400 years old. In Europe, the oldest known cave painting was of a red disk found in a cave in El Castillo, Spain, that has a minimum age of 40,800 years. The earliest figurative painting, of a rhinoceros, was found in the Chauvet Cave in France; it goes back 38,827 years.”

coolest story! a MUST READ!: Finding Clues in Genes of ‘Exceptional Responders’“One study at Memorial Sloan-Kettering Cancer Center tested a drug called everolimus that is approved for kidney and breast cancer. Researchers asked if it could treat bladder cancer. Forty-five patients received the drug. Two responded. ‘The verdict was, “O.K., I guess everolimus does not work in bladder cancer,” ‘ said Dr. David Solit, the principal investigator. But then there were those two patients — one, in particular. Her cancer had spread to her abdomen. She was expected to live less than a year, and there was no treatment for her. But with everolimus, her tumors disappeared. ‘I was at a clinical meeting, and everyone was saying this drug did not work,’ Dr. Solit said. ‘I said, “It worked for her.” ‘ The investigators found out why. Her cancer had a mutation in a gene that made it dependent on a protein, mTOR, for growth. Everolimus squelches the activity of mTOR. The woman is still taking everolimus, and her cancer has not recurred.”

The high heritability of educational achievement reflects many genetically influenced traits, not just intelligence“Genetic research has shown that intelligence makes a major contribution to the heritability of educational achievement. However, we show that other broad domains of behavior such as personality and psychopathology also account for genetic influence on GCSE scores beyond that predicted by intelligence. Together with intelligence, these domains account for 75% of the heritability of GCSE scores. These results underline the importance of genetics in educational achievement and its correlates.” – (because there’s more to hbd than just iq!)

The role of lactase persistence in precolonial development“It is shown through a number of specifications that country-level variation in the frequency of lactase persistence is positively and significantly related to population density in 1,500 CE; specifically, a one standard deviation increase in the frequency of lactase persistent individuals (roughly 24 percentage points) is associated with roughly a 40 % increase in precolonial population density.”

Common variants and the biological and genomic architecture of human height“The latest from the GIANT collaboration. They are also estimating ~ 10k causal variants in total, with 697 now identified at genome-wide significance…. With ~1k variants to work with, we can expect progress on the question of whether the ~1 SD group difference in height between north and south europeans is due to selection. Uniformly higher SNP frequencies in the north for variants that slightly increase height would be strong evidence of selection.” – original research paper: Defining the role of common variation in the genomic and biological architecture of adult human height

Researchers are now discovering that these mutations play a big role in developmental delay disorders. The baffling symptoms are a consequence of the underlying genetic turmoil…. These large mutations are called ‘copy number variants’ or CNVs, and they add or subtract copies of genes.”

We show that: (1) African poverty is falling rapidly…. All classes of countries, including those with disadvantageous geography and history, experience reductions in poverty. In particular, poverty fell for both landlocked as well as coastal countries; for mineral-rich as well as mineral-poor countries; for countries with favorable or with unfavorable agriculture; for countries regardless of colonial origin; and for countries with below- or above-median slave exports per capita during the African slave trade.” – h/t mugwump!

Ethnic Divisions and Production in Firms“A body of literature suggests that ethnic heterogeneity limits economic growth. This paper provides microeconometric evidence on the direct effect of ethnic divisions on productivity. In team production at a plant in Kenya, an upstream worker supplies and distributes flowers to two downstream workers who assemble them into bunches. The plant uses an essentially random rotation process to assign workers to positions, leading to three types of teams: (a) ethnically homogeneous teams, and teams in which (b) one or (c) both downstream workers belong to a tribe in rivalry with the upstream worker’s tribe. I find strong evidence that upstream workers undersupply non-coethnic downstream workers (vertical discrimination) and shift flowers from non-coethnic to coethnic downstream workers (horizontal discrimination), at the cost of lower own pay and total output.” – spite! it’s so funny. – h/t ben southwood!

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. One language is written on top of the other, which is why the second language remained hidden for so long.”duons. – see also Exonic Transcription Factor Binding Directs Codon Choice and Affects Protein Evolution.

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.”

H. Heidelbergensis Preferred Island Life“[B]etween 500,000 and 200,000 years ago, Homo heidelbergensis preferred to live on islands in the flood plains of major rivers, where they would have had access to big herbivores that grazed on the rich grasses, water birds and plants with edible roots, and leafy vegetables. 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.

Human brain hard-wired for rural tranquillity“Humans may be hard-wired to feel at peace in the countryside and confused in cities – even if they were born and raised in an urban area…. 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.”

(note: comments do not require an email. hi there!)

there was a little discussion (starting here) in the recent linkfest comments about whether or not the brain runs on autopilot and what that means for concepts like responsibility and free will and all that.

benjamin libet was the first guy to experimentally document that the subconscious brain seems to decide upon an action before the conscious mind “decides” to do it. his experiment has been successfully repeated many times, most recently using a different methodology (but winding up with the same, or a similar, result — i.e. subconscious decides what to do first). the wikipedia page on the neuroscience of free will has some excellent descriptions of the experiments. from that page:

“One significant finding of modern studies is that a person’s brain seems to commit to certain decisions before the person becomes aware of having made them. Researchers have found delays of about half a second. With contemporary brain scanning technology, scientists in 2008 were able to predict with 60% accuracy whether subjects would press a button with their left or right hand up to 10 seconds before the subject became aware of having made that choice…. It may be possible, then, that our intuitions about the role of our conscious ‘intentions’ have led us astray; it may be the case that we have confused correlation with causation by believing that conscious awareness necessarily causes the body’s movement. This possibility is bolstered by findings in neurostimulation, brain damage, but also research into introspection illusions.”

exactly.

given what we also know about all the cognitive biases that we humans have, along with the heritability of certain traits like religiosity and political persuasion — aspects of ourselves and our lives that we all just feel that we’ve really thought about and independently made up our minds about, even though … heh … the truth is that we’ve prolly just inherited a certain package of genes from our parents — all of these things make me distrust what our conscious minds tell us. the conscious mind, pardon the antropomorphism, wants us to feel that we’re making all the decisions, but that’s probably just a useful adaptation — an illusion of our neocortex, a more recently developed brain structure which has been jerry-rigged on top of more ancient brain structures.

as an hbd-ist, i would guess that probably some individuals have more “free will” than others — some people can probably use their conscious minds as more of a veto on automatic behaviors, for instance, although that that happens at all is by no means certain either. i would also guess that some populations have more “free will” than others, too.

dennis said the other day:

“The waning of religious and nationalistic beliefs means that biology plays a greater role…. Modern science has disillusioned us of our former beliefs, the only belief remaining being the will to power, which is itself a manifestation of nature, in which every living thing lives at the expense of other living things.”

eh. i gotta disagree. ’cause i think this is a false dichotomy: religion vs. biology.

what is religion (or religious beliefs and practices) except an expression of our biology? (our biologies, in fact — that’s partly why we’ve got different religions.) religion is a manifestation of nature. our nature.

religion is just culture — which is just a product of our biology, afaics.

yup. i’m a reductionist. but, hey — reductionism works.
