Ancient DNA Links Native Americans With Europe“…from the complete nuclear genome of a Siberian boy who died 24,000 years ago — the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today’s Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or western Asia. The finding suggests that about a third of the ancestry of today’s Native Americans can be traced to ‘western Eurasia,’ with the other two-thirds coming from eastern Asia…. It also implies that traces of European ancestry previously detected in modern Native Americans do not come solely from mixing with European colonists, as most scientists had assumed, but have much deeper roots.” — see also: The First of the Mohicans from greg cochran.

Your face may have been sculpted by junk DNA“There is a huge degree of variation in human faces but, as family resemblances show, the overall shape is heavily constrained by genetics. However, so far, geneticists have identified only a small number of genes that influence the shape. These explain just a tiny fraction of the variation seen in human faces. According to Axel Visel of the Lawrence Berkeley National Laboratory in California and his colleagues, more variation is controlled by distant-acting enhancers. These are short sequences of DNA, in non-coding regions of the genome, that can influence the activity of the facial genes, even if they are a long way along the DNA strand.”

Behavior problems in preschool and child care centers may be an issue of genes“A new study suggests that some children may be genetically predisposed to developing behavioral problems in child care and preschool settings…. [B]irth parents who had high rates of negative emotion and self-control, based on a self-reported temperament scale, were more likely to have children who struggled with behavioral issues such as lack of self-control and anger, in child care centers. They controlled for adoptive parent’s characteristics, and still found a modest effect based on the genetic link.”

Your Ethnicity Determines the Species of Bacteria That Live in Your Mouth“[P]eople from each of the four different ethnic groups represented in the study (all participants self-identified as either Caucasian, African-American, Chinese or Latino) generally had similar species of bacteria, especially underneath the gums. As a result, simply by counting which varieties of bacteria appeared in this area, the researchers developed a model that was able to guess a person’s ethnicity with an accuracy significantly better than chance — it got it right 62 percent of the time. Some groups were even easier to identify via the bacteria than others: It could correctly identify Latinos 67 percent of the time and African-Americans with 100 accuracy. The variation along ethnic lines, they believe, is a reflection of genetics, not environment. That’s because, if you assumed that the mouth microbiome is totally dependent on environmental factors, you’d expect that members of the same ethnic group would have different mixes of bacteria depending on whether they were first-generation immigrants to the U.S. or had family histories that stretched back generations in the country. Instead, people’s background — in terms of foods they ate and other lifestyle trends — didn’t seem to have any correlation with the bacterial communities in their mouths. – h/t super bob!

Herpes virus genome traces the ancient path of human migration“Researchers…sequenced the genomes of 31 samples of herpes simplex virus type-1 to reconstruct how it hitchhiked on humans as they dispersed around the world. The results match the pattern proposed by the ‘Out of Africa’ theory, which has become the most widely accepted scenario for ancient human migration. The analysis showed that African strains of the virus contained the most genetic diversity — suggesting that they had the oldest roots.”

Genetic variation alters efficacy of antidepressant“Having a different form of a gene that regulates the brain chemical noradrenaline influences how well men remember negative memories after taking the antidepressant drug reboxetine, according to a study published in the October 23 issue of The Journal of Neuroscience. The findings demonstrate how genes can influence antidepressant response.” – see also: Genes predispose some people to focus on the negative.

Low historical rates of cuckoldry in a Western European human population traced by Y-chromosome and genealogical data“[W]e estimate that over the last few centuries, EPP rates in Flanders (Belgium) were only around 1–2% per generation. This figure is substantially lower than the 8–30% per generation reported in some behavioural studies on historical EPP rates, but comparable with the rates reported by other genetic studies of contemporary Western European populations. These results suggest that human EPP rates have not changed substantially during the last 400 years in Flanders and imply that legal genealogies rarely differ from the biological ones.” – h/t rob brooks!

‘Endowment Effect’ Not Present in Hunter-Gather Societies“‘The more isolated Hadza traded about 50 percent of the time — which is what rational people should do,’ Azevedo said.

Asymmetries in altruistic behavior during violent intergroup conflict“Some empirical studies on intergroup conflict in hunter-gatherer societies and chimpanzees indicate that fitness relevant risks and potential benefits of attacks and defenses might have differed substantially under ancestral conditions. Drawing on these studies, it is hypothesized that the success of defenses was much more important for individual and kin survival and that a disposition to act altruistically during intergroup conflict is thus more likely to evolve for the strategic situation of defense…. Analyzing detailed historical case data from 20th century wars, this study finds that altruistic behavior towards members of the in-group indeed seems to occur more frequently when soldiers are defending themselves and their comrades against enemy attacks.” – h/t hbd bibliography!

Friendship and Natural Selection“More than any other species, humans form social ties to individuals who are neither kin nor mates, and these ties tend to be with similar people. Here, we show that this similarity extends to genotypes. Across the whole genome, friends’ genotypes at the SNP level tend to be positively correlated (homophilic); however, certain genotypes are negatively correlated (heterophilic). A focused gene set analysis suggests that some of the overall correlation can be explained by specific systems; for example, an olfactory gene set is homophilic and an immune system gene set is heterophilic.” – via charles!

Darkness in Anthropology: A Conversation with Napoleon Chagnon“Probably the single most anthropologically unacceptable thing I did was to take ‘biology’ seriously…. I began using commonly known ways to ‘measure’ relatedness between organisms — Sewall Wright’s coefficient of inbreeding and its extended concept, the coefficient of relatedness. This was very unusual in cultural anthropology. In short, I was discussing Yanomamö kinship with *the biological meaning* of kinship in mind — at a time when the vast majority of cultural anthropologists assumed that ‘kinship’ and ‘the biological meaning of Yanomamö kinship’ were, at best, only vaguely similar and any allusion to this was generally ‘suspect.’ But since ‘kinship’ was traditionally a central focus of anthropological theory, I began developing ways to show precisely, using my meticulous genealogies on the Yanomamö, that people took sides in fights according to how closely *genetically* they were related to each other and fought against people they were *less related to genetically*. Many of the most prominent anthropologists held the extreme view that ‘kinship’ among humans had *nothing* to do with the biological meaning of kinship as is assumed in the fields of biology, genetics, or animal husbandry. A common claim was something to the effect that ‘whatever kinship among humans was about, it was NOT about biology.’” – h/t g-nice!

Penn Biologists Show That Generosity Leads to Evolutionary Success – stewart and plotkin “examined the outcome of the Prisoner’s Dilemma as played repeatedly by a large, evolving population of players.

the fruit tree theory of the origins of agriculture:

this is the reigning paradigm here at home at the moment.

i’ve always had a hard time imagining why a bunch of hunter-gatherers would suddenly think: “i know! let’s settle down here and plant some flax seeds!”

-??-

but i can much more easily picture bunches of hunter-gatherers wandering around the fertile crescent (or wherever) — probably mainting territories — and especially defending spots where there were groves of fruit trees (figs, date palms).

all sort of animals, including other primates, defend fruit trees. and why wouldn’t you?! it’s a delicious, nutrious, rich food source:

if i, as a hunter-gatherer, came across a bunch of date palms, i’d probably plant myself next to them to make sure to collect the fruit for me and my family (like these folks are doing) …

… and then maybe i’d think about planting some grain seeds nearby, since i’d be hanging around the neighborhood for a while anyway.

i guess this is a sorta variation on the old oasis theory to explain the start of agriculture, although you don’t need the drying climate part of that theory. presumably somebody has already thought of this fruit tree idea.

(note: comments do not require an email. keep your hands off the fruit!)
