Stone Age skull from Kenya reveals astonishing human diversity“A partial human skull found at a site in Kenya suggests early humans living in Africa were incredibly diverse. The 22,000-year-old skull is not a new species and is clearly that of an anatomically modern human, but is markedly different from similar finds from Africa and Europe from the same time, the researchers said…. [T]he new findings suggest that during this early period of human history, Africa may have supported even greater human diversity, with small, offshoot lineages that no longer exist today….”

Division of labor by sex and age in Neandertals: an approach through the study of activity-related dental wear“The study reveals that all individuals have cultural striations, but those detected on the adult females are longer than the striations found in adult males. Regarding the distribution of dental chipping, the prevalence of this trait is higher in the maxillary dentition of males whereas females have the majority of dental chipping on their mandibular teeth. T he differences detected on the overall activity-related dental wear pattern denote a difference or a division of labor by age and sex in Neandertals while using the mouth as a third hand, i.e., in activities other than the provisioning of food, and provide new evidence for the lifestyle of this Pleistocene fossil human species.” – h/t paleogenomics!

Y chromosomes and Catalan surnames“‘By genotyping 17 Y-STRs and 68 SNPs in ~2500 male samples that each carried one of the 50 selected Catalan surnames, we could determine sets of descendants of a common ancestor, the population of origin of the common ancestor, and the date when such a common ancestor lived. Haplotype diversity was positively correlated with surname frequency, that is, rarer surnames showed the strongest signals of coancestry. Introgression rates of Y chromosomes into a surname by non-paternity, adoption, and transmission of the maternal surname were estimated at 1.5−2.6% per generation, with some local variation. Average ages for the founders of the surnames were estimated at ~500 years, suggesting a delay between the origin of surnames (twelfth and thirteenth centuries) and the systematization of their paternal transmission. We have found that, in general, a foreign etymology for a surname does not often result in a non-indigenous origin of surname founders; however, bearers of some surnames with an Arabic etymology show an excess of North African haplotypes.'” – @dienekes’.

Low IQ ups risk of heavy drinking among men“The researchers analysed data collected from 49,321 Swedish males born during 1949 to 1951 and who were conscripted for Swedish military service from 1969 to 1971. IQ results were available from tests performed at conscription, and questionnaires also given at conscription provided data on total alcohol intake (consumed grams of alcohol/week) and pattern of drinking, as well as medical, childhood and adolescent conditions, and tobacco use. Adjustments were made for socio-economic position as a child, psychiatric symptoms and emotional stability and the father’s alcohol habits. ‘We found that lower results on IQ tests in Swedish adolescent men are associated with a higher consumption of alcohol, measured in both terms of total intake and binge drinking,’ Sjolund said.” h/t ruta akula!

The entire worldview is based on the tabula rasa idea of human nature which is contradicted by science. The blank slate makes the progressive goal of equality of outcomes possible; indeed, if equality is not achieved there can only be nefarious forces at work and ‘more work to be done’.” – from ed west. see also Fancy a job in academia or the media?

Islam Is Not a Religion of the Book“By this, I mean that as a whole humans are prone to accepting the primary causal role of reflective cognition, of beliefs avowed and rationales offered. We are confident in our conscious self control, despite a robust body of cognitive psychology which implies that much of our cognition is not under the control or constraint of rational faculties. This problem is particularly extreme among intellectuals, the very class which also attempts to understand human phenomena. Through the simple process of introspection and extrapolation intellectuals tend to reduce human action to the outcome of ratiocination, inference from eternal axioms. This is wholly inadequate to a phenomenon as complex as religion.” – from razib.

Old India’s Village of Warriors Becomes Birthplace of Bouncers“Look closely and it becomes clear that the bouncers are all of a single physical type, their chests and biceps built like the front bumper of a sport utility vehicle. If they look like cousins, it is because they are. A startling number of them share a family name, Tanwar, and when the nightclubs close many will return to the same nearby village, a place where women walk down dusty lanes with their faces obscured by a cloth, balancing stacks of dried cow dung on their heads, much as their ancestors did three centuries ago…. The musclemen from the village of Fatehpur Beri are the descendants of the original inhabitants of the city, a genetic line that fortified itself over the course of centuries as they defended their village against waves of invaders on their way to the seat of empire. The sons and grandsons of cow and goat herders, they were born in an outpost surrounded on all sides by croplands. As Fatehpur Beri was swallowed by the expanding city, its spartan strongmen continued to train in the traditional way, stripping down to loincloths and wrestling in a circle of mud. But they were forced to look for a new line of work. ‘There is an element of the warrior in the Tanwars,’ said Ankur Tanwar, who opened the village’s first gym about a decade ago. ‘We fought with the Muslim invaders. We fought with the Britishers.'”

Our Cats, Ourselves“Which brings us to the genome of one critical tame animal: ourselves, humans. The Nobel Prize-winning zoologist Konrad Z. Lorenz once suggested that humans were subject to the same dynamics of domestication. Our brain and body sizes peaked during the end of the last ice age, and declined with the spread of agriculture…. Our cultural flexibility and creativity since the end of the ice age have not freed humans from evolutionary forces, but have opened up novel and startling paths. Thinking of domestication as an evolutionary process that occurs through ‘artificial’ selection creates a false dichotomy of nurture and nature that plays into a conceit of human exceptionalism. In fact, the idea that we are apart from nature, that it is ours to tame and exploit, is an outmoded approach. A more useful interpretation is that over the past 10,000 years, humans fashioned their own ecosystem. We were part of a natural process that altered the landscape…. The same forces that reshaped the genomes of our domesticates also reshaped ours.” – from razib. in the new york times! (^_^)

Ancient Easter Islanders Interbred With Native Americans“According to the recent study conducted by geneticists, the ancient inhabitants of Easter Island met and interbred with Native Americans long before Westerners arrived…. The recent genetic study is published on Thursday in the Current Biology journal. According to the study, these ancient people had significant contact with Native Americans hundreds of years ago, before the westerners reached the Island in 1722…. The finding of the study suggests that the intermixing occurred 19 to 23 generations ago. The researchers said that the Polynesian people (Rapa Nui’s) are not believed to have started mixing with Europeans until much later, the 19th century. Malaspinas said the genetic ancestry of today’s Rapa Nui people is roughly 75% Polynesian, 15% European and 10% Native American.”

Do Chinese people get bored less easily?“Advanced farming — intensive land use, task specialization, monoculture — has profoundly shaped East Asian societies, particularly China. This is particularly so for rice farming. Because the paddies need standing water, rice farmers must work collectively to build, dredge, and drain elaborate irrigation networks. Wheat farming, by comparison, requires no irrigation and only half as much work. Advanced farming seems to have favored a special package of predispositions and inclinations, including greater acceptance of monotony. This has been shown in two recent studies.” – from peter frost.

The mob wanted to avenge the deaths but, this being a colony where people passionately believed in their ancestral English liberties, ‘due process’ was followed – a term that dates back to the Parliament of Edward III but was obviously influenced by Clause 39 of the Magna Carta. Due process is what was followed in the Ferguson case, but maybe that’s just a boring old racist Anglo-Saxon idea that we can forget about now (grand juries are literally Anglo-Saxon, dating back to the reign of Ethelred II, or possibly the vibrant culturally-enriching Viking maniac King Canute).” – from ed west.

They have the opportunity to provide love and nurturing to a child who needs it. There are few better things that human beings can do with their time. The second answer is that they, like biological parents, are not miracle-workers. They will be unable to mold the child. Sometimes their adopted child will experience problems that are not the adoptive parents’ fault; sometimes they will reveal gifts of talent and character that are equally not to the adoptive parents’ credit. What is to the credit of good parents, adoptive and biological alike, is enfolding the child in love.” – from charles murray…who’s really just a big softie after all.

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.

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.
