(…also, i think that’s some really bad french! (*^_^*) )

seriously, tho. this is not me returning to blogging. sorry! i think i need another week or so of r&r.

but, i have been binge watching a lot of netflix shows/youtube videos, and i thought i’d share one with you: a bbc horizon documentary from 2011 — Are We Still Evolving? — hosted by one dr. alice roberts.

for the first ten or fifteen minutes, you might feel like poking out your eyeballs, but the show does get better and quite adequately explains rapid evolution, recent human evolution, and even — *gasp* — human biodiversity, albeit only such “nonthreatening” aspects of hbd like lactase persistence and high-altitude adaptations. still, it’s pretty cool that the show goes there at all.

of course roberts gives behavioral genetics a wiiiiiide berth. in fact she doesn’t even mention biological/genetic explanations for behavioral traits at all — until near to the end when she talks to the very frank dr. jeffrey steinberg about genetic engineering and intelligence briefly comes up. oops!

pay close attention to what stephen stearns has to say at ca. 47:45:

“Well I think what is very probably going on is that selection is moving a population up and down all the time. It goes off in a certain direction for a while, and then it goes back in the other direction. It’s only if you get a significant change in the environment that it will then continuously go in a new direction.”

in other words, the average frequencies of genes in populations matter, and those frequencies can vary over time depending up the selection pressures.

k. that’s all i’ve got for you. back to my la-z-boy. enjoy! (^_^) :

…for good behavior? (~_^)

sorry for the lack of posting lately. annoyingly, i am still unwell. ugh. =/

looks like i’ll have to have surgery or an alternative procedure to take care of the problem.

i hope to be back on my feet in 4-6 weeks or so…maybe 8…but i don’t plan on blogging in the meantime. i’m terrible at multitasking and so i just can’t blog and lie around on the sofa feeling sorry for myself at the same time. (~_^)

you might find me hanging out on twitter if i’m feeling up to it, although i haven’t even been pressing the retweet button for the last couple of weeks. =/ if you’re not on twitter, you can find my twitter feed below (↓) toward the bottom of the middle column.

if you’ve emailed me recently or dm-ed me on twitter, sorry i haven’t replied. i’ll try to get back to you as soon as i can!

so, i am alive! will be back soon! enjoy the end of your summer! (^_^)

here’s an excerpt from ed west‘s latest kindle single, Asabiyyah: What Ibn Khaldun, the Islamic father of social science, can teach us about the world today (u.k. link) [kindle locations 256-286]:

“As a rule, the English are not a very family-orientated people. Social life lacks the warmth of the Mediterranean world with its joyful and welcoming extended families. In contrast, many English people don’t especially like their relatives or are apathetic towards them. My father never took much interest in his relations, many of whom are fascinating, lovely people, and it was largely left to my Irish mother to maintain a connection. Meanwhile her family have always been close and this extends to first and second cousins in the more traditional west of Ireland. To the English, although family connections do count, they matter less, and associations with a school, club or other institution define them more.

“Yet despite there being no big fat English weddings with lots of relations called Nigel or Rupert, there are great advantages to a society with weak family connections. It is not a total coincidence that it was in England that clubs first took off in the 17th century, playing an important role in the country’s political and economic growth; in specific cases clubs allowed inventors to meet investors, but they also helped expand the general levels of trust. Countries that are not clannish tend to have far more clubs, institutions and other organizations that are collectively called ‘civil society’. In contrast societies with strong families tend towards low civic capital and in consequence higher corruption. This is reflected in the political cultures of different states.

“Asabiyyah, therefore, can work in two ways; the group feeling can lie at the nationwide level, or it can exist within tribes, clans or religious communities, and this has a profound effect on a state’s institutions and how well a democracy can function.

“At the other end of the spectrum to the English are the Bedouin, whose famous phrase ‘me and my brother against my cousin, me and my cousin against the world’ reflects concentric circles of trust, one limited to family members.

“Mark Weiner wrote in The Rule of the Clan about countries governed by ‘clannism’ that: ‘These societies possess the outward trappings of a modern state but are founded on informal patronage networks, especially those of kinship, and traditional ideals of patriarchal family authority. In nations pervaded by clannism, government is co-opted for purely factional purposes.’

“In these societies, especially in the Middle East and Africa, ‘the nuclear family, with its revolutionary, individuating power, has yet to replace the extended lineage group as the principle framework for kinship or household organization’.

“Clannish states have little sense of wider civic asabiyyah and therefore civic responsibility. Indeed, as social anthropologist Stanley Kurtz wrote, tribes were used to preying on others: ‘Once a particularly powerful tribe or tribal coalition actually captured a state, they simply routinized their predation under official guise. (Saddam and his Sunni tribal allies fit the bill.) The state, such as in the Middle East, offers but a thin alternative to ‘the war of all against all’. Too weak to provide public utilities, policing, or impartial justice, most Middle Eastern states are just reincarnations of the predatory, winner-take-all tribal coalitions of old. Why exchange the protection of your family, tribe, or sect for submission to a weak or predatory state?’

“The relationship between this type of state and the tribal peasant, wrote Philip Carl Salzman of McGill University in Canada, ‘is that of the shepherd to his flock: the state fleeces the peasants, making a living off of them, and protects them from other predators, so that they may be fleeced again’. Salzman describes such clan-based states as ‘cliques determined to impose their power for the pleasure of dominance and the profit of extortion’. The inevitable result of clannism is kin-based corruption whereby resources, positions and other rewards are monopolised within family groups. Nepotism is found wherever humans are, but is far more widespread in clannish societies, and this affects both a country’s corruption levels and its ability to sustain democracy.”

that's no planet

it’s never too early to get organized for christmas, right?! if you’re wondering what to get me this year, here’s my wishlist. well, it’s more like a wish-item, ’cause there’s only one thing on the list (h/t to kristen for pointing this out to me — thanks, kristen! (^_^) )…

raymond of penyafort‘s Quia Tractare Intendimus with TABLES OF CONSANGUINITY AND AFFINITY!! (^_^) an illuminated manuscript on vellum in latin created by raymond while he was scribing away in mid-13th century paris:

raymond of penyafort

the manuscript will be up on the auction block at christie’s tomorrow (july 15th), and it’s estimated to go at between $46,500 and $77,500, so it’s a steal really! (>.<)

raymond sounds like he was my kinda guy, btw:

“Having reached his 60th year, Raymond retired to a reclusive life in Barcelona.

“Within the year, however, Raymond was appointed to the position of Archbishop of Tarragona, the capital of the Kingdom of Aragon, over his strenuous objections. He did not appreciate the honor bestowed on him and ended up getting sick and resigning within two years.

“Raymond returned to Barcelona in 1236. Not long able to remain in seclusion, however, he was elected the Master of the Order of Preachers by the General Chapter of 1238. He immediately set out on foot to visit all the houses of friars and nuns of the Order. Even in the midst of this, he was able to draft a new set of Constitutions of the Order, in which he included a resignation clause for the Master. When it was adopted by the next General Chapter of 1240, he immediately took advantage of that option.”

heh! =P

seriously. if you’ve got a spare 46-77K lying around and feel like purchasing raymond’s manuscript, please donate it to an appropriate library/archive!

even more seriously, if you’ve got any spare cash lying around at all (check under the sofa cushions!), give it to greg cochran. (^_^)

p.s. – i have to go off and do some hospitaly/medical testy things. back in a few days! (^_^) behave yourselves!

Whole genome sequence analyses of Western Central African Pygmy hunter-gatherers reveal a complex demographic history and identify candidate genes under positive natural selection“African Pygmies practicing a mobile hunter-gatherer lifestyle are phenotypically and genetically diverged from other anatomically modern humans, and they likely experienced strong selective pressures due to their unique lifestyle in the Central African rainforest…. Our two best-fit models both suggest ancient divergence between the ancestors of the farmers and Pygmies, 90,000 or 150,000 years ago. We also find that bi-directional asymmetric gene-flow is statistically better supported than a single pulse of unidirectional gene flow from farmers to Pygmies, as previously suggested…. We found that genes and gene sets involved in muscle development, bone synthesis, immunity, reproduction, cell signaling and development, and energy metabolism are likely to be targets of positive natural selection in Western African Pygmies or their recent ancestors.”

Directional dominance on stature and cognition in diverse human populations“[I]ncreased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.” – see also Not tonight, cousin from dr. james thompson. and see also Inbreeding from greg cochran. and see also Directional dominance on stature and cognition from steve hsu.

Heritability and the evolution of cognitive traits

CNVs in neuropsychiatric disorders“Over the last few years at least 11 copy number variations (CNVs) have been shown convincingly to increase risk to developing schizophrenia: deletions at 1q21.1, NRXN1, 3q29, 15q11.2, 15q13.3 and 22q11.2, and duplications at 1q21.1, 7q11.23, 15q11.2-q13.1, 16p13.1 and proximal 16p11.2. They are very rare, found cumulatively in 2.4% of patients with schizophrenia and in only 0.5% of controls. They all increase risk for other neurodevelopmental disorders, such as developmental delay and autism spectrum disorders, where they are found at higher rates (3.3%). Their involvement in bipolar affective disorder is much less prominent. All of them affect multiple genes (apart from NRXN1) and cause substantial increases in risk to develop schizophrenia (odds ratios of 2 to over 50). Their penetrance for any neurodevelopmental disorder is high, from ∼10% to nearly 100%. Carriers of these CNVs display cognitive deficits, even when free of neuropsychiatric disorders.”

Is the Romantic–Sexual Kiss a Near Human Universal – apparently not! – “The romantic–sexual kiss was present in a minority of cultures sampled (46%). Moreover, there is a strong correlation between the frequency of the romantic–sexual kiss and a society’s relative social complexity: the more socially complex the culture, the higher frequency of romantic–sexual kissing.”
