Not as the crow flies
A comment below:This thought has probably occurred to others as well, but isn’t it interesting that if this theory of Baltics being the “true” Europeans is correct, that history repeated itself several thousand years later when the Baltic peoples becam…

Where are the “Paleolithic Europeans”?
Over at my other blog I have a review up of a new paper in PLoS Biology. The authors argue that a particular Y haplogroup lineage, R1b1b2, which has often been assumed to be a marker of indigenous Paleolithic Europeans (i.e., those who were extant befo…
The few and the many
John Hawks has some commentary on a Nicholas Wade article which previews a new paper on long term effective population size in humans, soon to be out in PNAS (Wade’s piece states that it’ll be out tomorrow, but it’s PNAS). Wade states:They put the numb…
Ant fiction
Steve points me to an except from E. O. Wilson’s new ant novel in The New Yorker. In the late 1990s I read Empire of the Ants, which had a significant ant-centric aspect. A friend who later went on to do graduate work in entemology borrowed it from me,…
A model of the history of human misery
In the comments below I was outlining a simple model which really is easiest to communicate with a chart. I removed the labels on the Y and X axes because the details don’t matter, the X axis is simply “time,” and the Y axis simply reflects the magnitu…
Blind men prefer thin-waisted women
The waist-to-hip ratio research has been done to death, but an interesting twist, Blind men prefer a low waist-to-hip ratio:Previous studies suggest that men in Western societies are attracted to low female waist-to-hip ratios (WHR). Several explanatio…
Agriculture & health in the pre-Columbian period
I’ve been interested in the transition toward agriculture, and its relationship to human health, for a while. There seem to have been two dominant paradigms in anthropology over the past century. The first is that agriculture spread because it was supe…
After the fact
Daniel Larison has a post up where he criticizes a David Brooks column. Here’s what Larison observes (Brooks’ quote within):David Brooks is right that culture and habits matter, but this one line rang false:There is the influence of the voodoo religion…
City squalor
I recently read The Fires of Vesuvius: Pompeii Lost and Found & Roman Passions: A History of Pleasure in Imperial Rome. Got me in the mind of thinking more about the history of city life, and what it was like in the past, and how it compares to my …
Levelling off of the “Obesity Epidemic”?
There’s a lot of media buzz right now about a new report in JAMA on the empirical trends on prevalence of obesity in the United States. You can read the whole paper here (too many tables, not enough graphs). Interestingly, like George W. Bush it seems …

Frequent Cognitive Activity Compensates for Education Differences in Episodic Memory:Results: The two cognitive measures were regressed on education, cognitive activity frequency, and their interaction, while controlling for the covariates. Education a…
The Dark Age Mighty Whitey
This week David Brooks has a column up on the messianic variant of the “Mighty Whitey” motif. Steve points out that this is a relatively old genre, with roots back to the Victorian period. And, it also has basis in fact. Consider the White Rajahs of Sa…
On the cusp
Lots of talk about how the “underwear bomber” was from a wealthy and cosmopolitan background in the media. Like the poverty = crime meme, the poverty & backwardness = terrorism meme is still floating around, though the evidence of the past decade o…
How Chinese relate to each other and the Japanese
Last month I pointed to a paper on Chinese population structure, Genomic Dissection of Population Substructure of Han Chinese and Its Implication in Association Studies. One to note was that the average FST differentiation Han populations was on the or…
