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.

Black men have lower sperm counts than white men – @race/history/evolution notes.

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.”

Is Beauty in the Face of the Beholder?“We concluded that individuals, if given the opportunity, seek to promote ‘positive assortment’ for Self’s phenotype, especially when the level of similarity approaches an optimal point that is similar to Self without causing a conscious acknowledgment of the similarity.” – on assortative mating, via race/history/evolution notes.

3.4-7.9% Neandertal admixture in Eurasia?“‘Our analysis allows us — for the first time — to formally reject a history of ancestral population structure and instead reveals strong support for admixture from Neandertals into Eurasian populations at a higher rate (3.4%-7.9%) than suggested previously.’” – @dienekes’.

and speaking of neanderthals: Neanderthals made leather-working tools like those in use today.

Genetics and alcoholism“Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person’s risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2.”

Jason Richwine and some Hispanic data“In summary, if one uses scholastic data as a measure of ability, then there was some significant narrowing of the White/Hispanic gap in the early 1980’s, but that reduced gap has persisted thereafter. This finding discomforts those who predicted that the gap would never change, and those who said it was closing fast and would shortly disappear. Both are wrong, are partially right.” – from dr. james thompson.

Population Structure of Hispanics in the United States: The Multi-Ethnic Study of Atherosclerosis“By comparing genetic ancestry of MESA Hispanic participants to reference samples representing worldwide diversity, we show major differences in ancestry of MESA Hispanics reflecting their Caucasian, African, and Native American origins, with finer differences corresponding to North-South geographic origins that separate MESA Mexican versus Central/South American samples. Based on our analysis, we define four subgroups of the MESA Hispanic cohort that show close agreement with the following self-identified regions of origin: Dominican/Cuban, Mexican, Central/South American, and Puerto Rican.” – via nelson.

Those in the mean group liked the meal less as the burn increased, but not nearly as rapidly as those below the mean.”

The Ignorance of Voters“Why does more education lead to less accurate beliefs? The answer returns us to the difference between rational voters (what we think we are) and rationalizing voters (what we really are). It turns out that the human mind is a marvelous information filter, adept at blocking out those facts that contradict what we’d like to believe.”
