Polygamy and human evolution: maybe it’s agriculture
Eric Michael Johnson has a fascinating piece in Psychology Today, Sex, Evolution, and the Case of the Missing Polygamists. I want to spotlight a few paragraphs:
Keep in mind that in terms of interpreting such genetic evidence we are of necessity confined to a fairly recent time depth (and remember, by “recent” someone like me means […]
The hobbits were cretins. Perhaps. Or perhaps not
I was thinking a bit about H. floresiensis today. Probably my thoughts were triggered by John Hawks’ post on the propensity for paleontologists to be “splitters,” naming new finds as species when they’re not. The issue with H. floresiensis is a little more cut & dried: if they weren’t a separate species they were obviously […]
The city that kills you makes you strong!
Over the past day I’ve seen reports in the media of a new paper which claims that long-term urbanization in a region is strongly correlated with genetic variants for disease resistance. I managed to find the paper on Evolution’s website as an accepted manuscript, ANCIENT URBANISATION PREDICTS GENETIC RESISTANCE TO TUBERCULOSIS:
A link between urban living […]
Swedes are not sexist or nativist
A party, the Sweden Democrats, is about to enter the Swedish parliamanent which is described in this way in Wikipedia:
The party has its origins in the nationalist movement Bevara Sverige Svenskt (”Keep Sweden Swedish”)…During the mid 1990s, the party leader Mikael Jansson strove to make the party more respectable, modelling it after other “euronationalist” parties, […]
Of Iran, Turan, and Turks
There’s a new paper out in The European Journal of Human Genetics which is of great interest because it surveys the genetic and linguistic affinities of two dozen ethno-linguistic groups from the three Central Asian nations of Uzbekistan, Kyrgyzstan, and Tajikistan. This is what the Greeks referred to as Transoxiana, and the Persians as […]
Not all genes are equal in the eyes of man
A few days ago I was listening to an interview with a reporter who was kidnapped in the tribal areas of Pakistan (he eventually escaped). Because he was a Westerner he mentioned offhand that to “pass” as a native for his own safety he had his guides claim he was Nuristani when inquiries were made. […]
The pristine Amazon – a zone of contention
Last week there was an article in The Washington Post that caught my eye, Scientists find evidence discrediting theory Amazon was virtually unlivable. The headline flattens a complex and roiling debate within academia. A generation ago the forests of the Amazon basin were seen as a pristine climax ecosystem. In the 1990s and 2000s […]
The naked years
When I talk about sexual selection I usually make sure to have an accompanying visual of a peacock to go with the post. But really I could have used a dandy as an illustration, or perhaps in our day & age “The Situation”. Unlike the peacock much of what passes for human “plumage” is not […]
The New World in three easy steps
One aspect of human demographic expansions seems to be the fact that we often model them as a constant diffusion process, when in reality there were likely pulses (economic historians can conceive of this as the periodic gaps between land and labor factor inputs). I don’t know much about the human movements prior to H. […]
Chosen genes of the Chosen People
Last spring two very thorough papers came out which surveyed the genetic landscape of the Jewish people (my posts, Genetics & the Jews it’s still complicated, Genetics & the Jews). The novelty of the results was due to the fact that the research groups actually looked across the very diverse populations of the Diaspora, from […]
Size doesn’t always matter
The autosomal genome of Ötzi the Austrian “Iceman” is apparently in the pipeline (from what I can tell they’re doing the analysis right now). What can we learn from one sample? Ann Stone, who was a graduate student on the original team which recovered his body, says:
A specialist in anthropological genetics, Stone is excited by […]
India’s Deep North
In my post Pakistan ~10 years on I alluded to the fact that despite India’s robust economic growth of the past ~15 years or so in the aggregate there is a wide range of state-by-state variation. It is conventional in the media to point out the massive caste/class divisions in India, but because of the […]
Empires of the Word & anti-Babel
To the left you see a map of the distribution of languages and language families in Europe. Language is arguably the most salient cultural feature of our species, as well as one of the most obviously biologically embedded. The trait of language is a human universal, to the point where even those without hearing can […]
Linguistic diversity, other views
Readers might find these responses of interest. Mostly I just laughed, though some of you may be a bit more serious than I, so if anthro-gibberish drives you crazy, don’t follow the links. As I told “ana” below a lot of the discussion we had was basically just talking past each other. I kept telling […]
Disease as a byproduct of adaptation
How we perceive nature and describe its shape are a matter of values and preferences. Nature does not take notice of our distinctions; they exist only as instruments which aid in our comprehension. I’ve brought this up in relation to issues such as categorization of recessive vs. dominant traits. The offspring of people of […]
Knowledge is not value-free
This isn’t The New Yorker, and I’m not writing twenty page essays which flesh out all the nooks and crannies of my thought. When I posted “Linguistic diversity = poverty” I did mean to provoke, make people challenge their presuppositions, and think about what they’re saying when they say something.
I think knowledge of many languages […]
The Human Edge (on NPR)
NPR has a series on Morning Edition titled “The Human Edge,” which explores human evolution and genetics. The first episode is up, Finding Our Inner Fish. They focus on Neil Shubin’s work (also, some reporting on what fish can tell us about human skin color on All Things Considered).
As a constructive criticism, I wonder if […]
The essence of pleasure
I highly recommend this discussion between Paul Bloom & Robert Wright. The topic under consideration is the psychology of pleasure, as reviewed in Bloom’s new book How Pleasure Works: The New Science of Why We Like What We Like. You can also find out about Bloom’s ideas in this exchange in Slate. The essentialism examined […]
The dismal gods
Larry Witham’s Marketplace of the Gods: How Economics Explains Religion is a manifestly ill-timed book. He states that “…around 2006 I began to notice a good deal of hoopla in the book market about economic explanations for just about everything-books that were best sellers.” Marketplace of the Gods was obviously written to capitalize on the […]
The English & Irish, together again
One of the peculiarities of the synthesis of 19th and early 20th historical linguistics and biological anthropology was the perception by many British thinkers that the English, as the scions of the Anglo-Saxons, were fundamentally a different race from the Celtic nations to their west, the Welsh and Irish, and the Scots to the north […]
