sorry for the delay! the sunday linkfest hasn’t appeared on a wednesday since … gee … the last time it appeared on a wednesday! (*^_^*)

Butterflies show origin of species as an evolutionary process, not a single event“The evolution of new species might not be as hard as it seems, even when diverging populations remain in contact and continue to produce offspring…. ‘We find that only a small fraction of the genome is markedly different between closely related species, but then much more of the genome — more than you’d expect — shows similar differences between more distantly related species…. That indicates that the genetic changes that are important for causing speciation are tightly clustered early in speciation, but not so later on in the process; the overall pattern of genome divergence starts slow and then skyrockets.’”

Mating advantage for rare males in wild guppy populations“Negative frequency-dependent selection (NFDS), a form of selection in which genotypes are favoured when they are rare, can potentially maintain such extensive polymorphism, but few experimental studies have confirmed its operation in nature…. Here we use highly replicated experimental manipulations of natural populations to show that males with rare colour patterns have higher reproductive fitness, demonstrating NFDS mediated by sexual selection. Rare males acquired more mates and sired more offspring compared to common males and, as previously reported, had higher rates of survival.” – h/t rob brooks!

Japanese north–south gradient in IQ predicts differences in stature, skin color, income, and homicide rate“In Japan, there is IQ gradient from north to south. Stature and average income cline is also from north to south. Homicide rates increase from north to south. Fertility rates and suicide rates decrease from north to south. Infant mortality is not correlated with latitude.”

Global patterns of sex-biased migrations in humans“We found that genetic differentiation between populations was higher for Y chromosome than for the mtDNA at global scales. The migration rate of female might be three times higher than that of male, assuming the effective population size is the same for male and female.” – h/t hbd bibliography!

Shape Differences Between the Faces of Homosexual and Heterosexual Men“Homosexual men showed relatively wider and shorter faces, smaller and shorter noses, and rather massive and more rounded jaws, resulting in a mosaic of both feminine and masculine features.” – h/t neuroskeptic!

The rule-dependence model explains the commonalities between the Flynn effect and IQ gains via retesting“[W]e propose that Flynn effect gains are partly a function of the degree to which a test is dependent on rules or heuristics. This means that testees can become better at solving ‘rule-dependent’ problems over time in response to changing environments, which lead to the improvement of lower-order cognitive processes (such as implicit learning and aspects of working memory). These in turn lead to apparent IQ gains that are partially independent of general intelligence. We argue that the Flynn effect is directly analogous to IQ gains via retesting, noting that Raven’s Progressive Matrices is particularly sensitive to both the effects of retesting and the Flynn effect.” – from woodley and armstrong! (^_^) – see also dr. thompson.

Civilizations rise and fall on the quality of their soil“Great civilisations have fallen because they failed to prevent the degradation of the soils on which they were founded…. This is according to Professor Mary Scholes and Dr Bob Scholes who have published a paper in the journal Science, which describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.”

Bad reporting generates bad arguments“The Sunday Times gets 3.5 million readers a week. Anything mentioned in it has a chance of influencing public understanding and opinion in Britain. Last week they did a piece on Professor Robert Plomin’s recent book ‘G is for Genes’ which focuses on the genetic contribution to scholastic achievement. The newspaper’s coverage was misleading….” – of course. – from dr. james thompson.

Embryo Selection for Cognitive Enhancement“We find that embryo selection, on its own, may have significant impacts, but likely not drastic ones, over the next 50 years, though large effects could accumulate over multiple generations. However, there is a complementary technology, stem cell-derived gametes, which has been making rapid progress and which could amplify the impact of embryo selection, enabling very large changes if successfully applied to humans.” – h/t mike anissimov!

Why Can’t We All Just Get Along? The Uncertain Biological Basis of Morality“[S]ome of our deepest moral intuitions are gut feelings that are with us for no more lofty a reason than that they helped our ancestors protect themselves and spread their genes.” – h/t urho lintinen! – see also: You Can’t Learn About Morality from Brain Scans.

War Before Civilization – from peter turchin.

Cooperation and conflict between women in the family“Reproductive competition within and between families may have underpinned the biological evolution of fertility patterns (such as menopause) and the cultural evolution of marriage, residence, and inheritance norms (such as late male marriage or primogeniture), which can enhance cooperation and minimize the observed incidence of such conflicts.”

Do human females use indirect aggression as intrasexual competition strategy? [pdf] – yes. (duh.) – h/t michael w. story!

Bone flute discovery indicates 9000 years of Chinese music tradition“Archaeologists announced the discovery of three ancient flutes made of red-crowned crane bones that may prove that Chinese have been playing music for 9,000 years. The flutes were excavated at an ancient tomb in the site of a Neolithic settlement in Henan Province…. The bone flutes, pictured above, are thought to be the world’s earliest heptatonic musical instruments ever discovered.”

Total Fertility Rate“Oversimplifying, if your tribe has 60 men and 40 women, if each woman has two kids during her lifetime, when the next generation turns over, your population will have declined from 100 people to 80. Conversely, if your tribe has 40 men and 60 women, and each woman has two kids, your tribe will have grown from 100 to 120. The female sex is the limiting factor when it comes to reproduction, after all.” – from the awesome epigone.

Earlier Onset of Puberty in Girls Linked to Obesity“[T]he respective ages at the onset of breast development varied by race, body mass index (obesity), and geographic location. Breast development began in white, non-Hispanic girls, at a median age of 9.7 years, earlier than previously reported. Black girls continue to experience breast development earlier than white girls, at a median age of 8.8 years. The median age for Hispanic girls in the study was 9.3 years, and 9.7 years for Asian girls. Body mass index was a stronger predictor of earlier puberty than race or ethnicity.” – h/t hbd bibliography!

What color are Whites?“In reality, most *Français de souche* act as individuals and have only a weak sense of their collective interest. Collective action is instead wielded by better organized factions, particularly the globalized business community—which lobbies hard to outsource employment to low-wage countries and insource low-wage workers.” – from peter frost.

bonus bonus: There’s a global morality gap — and it’s getting wider“It is now clear, though not much talked about, that humanity, all 7.1 billion of us, tends to fall into one of two distinct camps. On the one side are those who buy into the whole post-Enlightenment human rights revolution. For them the moral trajectory of the last 300 years is clear: once we were brutal savages; in a few decades, the whole planet will basically be Denmark, ruled by the shades of Mandela and Shami Chakrabarti. And there’s some truth in this trajectory — except for the fact that it only applies to half the planet. The other half resolutely follows a different moral code: might is right, all men were not created equal and there is a right and a wrong form of sexual orientation. You can identify those countries in the dark half of the divide by their attitudes to homosexuality and women; to honour killings, race, disability, mental illness, religious minorities and to crime, torture and punishment, even animal rights and the environment.” – h/t ed west!

Do Elite ‘Power Sport’ Athletes Have a Genetic Advantage?“A specific gene variant is more frequent among elite athletes in power sports…. A ‘functional polymorphism’ of the angiotensiogen (AGT) gene is two to three times more common in elite power athletes, compared to nonathletes or even elite endurance athletes, according to the new research by Paweł Cięszczyk, PhD, of University of Szczecin, Poland, and colleagues.”

Ballet Dancers’ Brains Adapt to Stop Them Getting in a Spin – or maybe they start off with somewhat different brain structures: “Scientists have discovered differences in the brain structure of ballet dancers that may help them avoid feeling dizzy when they perform pirouettes…. The brain scans revealed differences between the groups in two parts of the brain: an area in the cerebellum where sensory input from the vestibular organs is processed and in the cerebral cortex, which is responsible for the perception of dizziness. The area in the cerebellum was smaller in dancers.”

Math explains history: Simulation accurately captures the evolution of ancient complex societies“The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world. Intense warfare is the evolutionary driver of large complex societies, according to new research….” see also: Math and History Collide. response: No, math cannot predict the rise and fall of empires. (party pooper.)

Genetic study pushes back timeline for first significant human population expansion“Using new genetic tools, the authors conclude that the first significant expansion of human populations appears to be much older than the emergence of farming and herding, dating back to the Paleolithic (60,000-80,000 years ago) rather than Neolithic age (10,000 years ago). They also suggest that strong Paleolithic expansions may have favored the emergence of sedentary farming in some populations during the Neolithic.” – h/t malcolm pollack!

New Approach to Explaining Evolution’s Big Bang“[T]he Cambrian Explosion was preceded by a rise in sea level that submerged vast swaths of land, eroding the drowned rocks…. But these great floods also poisoned the ocean. The erosion of the coastlines released calcium, which can be toxic to cells. In order to survive, animals had to evolve ways to rid themselves of the poison. One solution may have been to pack the calcium into crystals, which eventually evolved into shells, bones, and other hard tissues. Dr. Smith doesn’t think it’s a coincidence that several different lineages of bilaterians evolved hard tissues during the Cambrian explosion, and not sooner.”

Understanding how infants acquire new words across cultures“[I]n English, 24-month-old infants were better able to learn novel verbs for novel actions (e.g., petting) if the surrounding noun phrases were explicitly mentioned (e.g., ‘The girl is petting the dog’) than if they were dropped from the sentence (e.g., ‘Look. Petting!’). In contrast, the new research shows that in Korean (a language in which noun phrases are typically dropped in conversation) 24-month-olds were better able to learn novel verbs for novel actions if the surrounding noun phrases (e.g., the girl, the dog) were dropped; in fact, unlike English-acquiring infants, those acquiring Korean struggled if the nouns were explicitly mentioned.” – don’t know, unfortunately, what the ethnicities of these infants are.

The Science Fiction Future of Genetic Genealogy“Next month at the American Society of Human Genetics 2013 meeting, researchers from AncestryDNA will present their work detailing the reconstruction of portions of the genomes of an 18th-century couple using detailed genealogical information and Identity-by-Descent (‘IBD’) DNA segments from several hundred descendants of the couple in the AncestryDNA database. In other words, researchers identified several hundred descendants of a certain couple living in the 1700s and then used the DNA shared by those descendants to recreate as much of the couples’ genomes as possible.” – cool! from the genetic genealogist.

Low-Hanging Fruit: Consider the Ant“Some spiders somehow fly by using silken threads. They’ve been detected at altitudes over 4 km, and more than a thousand miles from land. The usual notion is that these threads catch air currents, but that may not be the real explanation. For one thing, they seem to be able to take off fairly rapidly in a dead calm. It looks instead as if these spiders manage to impart a negative charge to these threads and are then propelled upward by the atmospheric electric field – electrostatic levitation, a totally novel mechanism for flight.” – whoa! – from greg cochran.

Brainwashed by a microbe?“*T. gondii* is being studied for possible behavioral effects mainly because it has attracted so much attention. But we’re probably being manipulated by other parasites. ‘A large number of parasitic organisms probably exist in helminths, protozoa, fungi, bacteria, archea and viruses that may influence the phenotype of their human host even more than the Toxoplasma. These organisms are, however, still waiting for research teams to engage in a systematic study of their influence on the human host.’” – from peter frost. previously.

When the Melting Pot Reaches a Boil“If there is one constant in the travails of *Homo sapiens sapiens*, it is that he gets on best with his own kind. Yet to the social engineers who would shepherd us into multicult euphoria, it is as if these millennia of inter-ethnic strife didn’t exist.”

It Must Be Said“There are facts that were once known, sometimes generally known, that are now known to but a few…. Many people assume that everyone is secretly aware of those unpleasant facts, but that is not the case. A generation that has grown up never hearing those facts will be almost entirely unaware of them, in part because their personal life experiences don’t impinge on those patterns much…. Anyhow, I intend to occasionally make a clear statement of some hateful fact – not necessarily because I have anything new to say on the subject (which is what I prefer).

Diabetes’ genetic underpinnings can vary based on ethnic background, Stanford studies say – the researchers “found a clear geographic pattern in the genetics behind type-2 diabetes. The genetic risk is highest for Africans and drops along the trajectory the first humans took when migrating out of Africa toward East Asia (primarily Japan, China and Korea), where diabetes-linked genes appear to be more protective. Based solely on what is currently known about type-2 diabetes genetics, native Africans would appear to be at higher risk for diabetes, while East Asians would appear to be protected.” – see also genetic risk world map|diabetes.

right after wwii for causing the most number of deaths. ever. that’s according to “The Great Big Book of Horrible Things” anyway.

doesn’t really seem fair to compare individuals — genghis (40M) and mao (40M) — with events like wwii (66M) (all figures are estimates, obviously). really, genghis and mao should be tied for first place in the solo finals.

this is pretty bizarre if (IF) it’s true:

Gaddafi ‘supplies troops with Viagra to encourage mass rape’, claims diplomat

“US ambassador Susan Rice has also said, without offering evidence, that Iran was helping Syria to suppress dissent

“One of America’s most senior diplomats claimed at the United Nations security council that Muammar Gaddafi is supplying his troops with Viagra to encourage mass rape, according to diplomats.

“Susan Rice, the US ambassador to the UN made the claim while accusing Gaddafi of numerous human rights abuses. Earlier in the week Rice also claimed, without offering any evidence, that Iran is helping Syria suppress internal dissent.

“Foreign affairs specialists expressed scepticism about both claims.

“The Viagra claim surfaced in an al-Jazeera report last month from Libya-based doctors who said they had found Viagra in the pockets of pro-Gaddafi soldiers. But it is a jump from that to suggesting Gaddafi is supplying troops with it to encourage mass rape….”

people talk about rape during war as a weapon (pretty right) used to terrorize populations. eh. yeah, i guess hoardes of men entering your town and raping and pillaging everyone|thing in sight would be terrorizing, but i think (of course) the real reason for rape during wartime is more fundamental than even that.

what’s war all about? eliminating your competitors, i.e. competitors for resources. how do you eliminate them? well, killing them for one. you can also try to replace their genes by impregnating the women of whatever population you’re fighting. then you reduce the mating opportunities for the guys in that other group (’cause all their women are now pregnant) AND you increase your own reproduction rate. it’s a win-win situation!

also, i would think some really strong reproductive urges kick in when you’re at war. your genes are prolly “thinking”: sh*t. we could be dead any second now! better mate!

rape during human wars is kinda like my favorite example of male lions taking over a pride: they kill (or try to kill) the current males in the pride, kill all the young uns, and then mate with all the females. reproductive success! it’s all that matters.
