But while Houghton begins and ends in the Pacific, I don't think they're the only population who have adapted to wet cold by evolving large, muscular bodies and short, thick limbs. This other bunch was in the news not too long agopic.twitter.com/oXXRoXKery
Hafþór Júlíus Björnsson recently deadlifted 1,105 pounds to break Eddie Hall's record, who himself had surpassed Benedikt Magnusson, yet ANOTHER Icelander. There are only 364,000 of these people in the world! These figure show strongest man finalists per mil in the 21st century:pic.twitter.com/GoWafBFYBK
When Iceland was first discovered agriculture was practiced on a large scale, but after the onset of the Little Ice Age most grain had to be imported and the people subsisted mostly on animal protein, especially fish.
One of the ways Icelanders have apparently adapted to their diet is by acquiring a mandibular torus, a kind of bony outcropping of the lower mouth only seen at the same frequency in the Eskimo, who have a similar hard diet that places great stress on the jaw.
But unlike the Eskimo, since about 1200 fish have been exported on a very large scale from Iceland and the people there have engaged in the activity on a scale unheard of in Europe. As late as 1880, 41% of people in Reykjavík fished for a living and in ultra-cold waters.
Carleton’s 1939 The Races of Europe has a treasure trove of pre World War II anthropological information, but I can’t find any hard numbers on Icelandic arm span. But my rough impression is that they are extremely short limbed. Here for example is the Icelandic Michael Jordan:pic.twitter.com/LaTPYHA87p
But Coon does have relative span (armspan/height) measurements from many other Europeans and the list helps to identity a third population that has also adapted to wet cold in the accustomed way:pic.twitter.com/ZjzfqbGv3F
Montenegrins were both the tallest and shortest armed people in Europe in 1939 and the same is true today. A 2012 study replicated the finding of a tiny 1.01 wingspan, which is even more anomalous when you consider, as Coon did, that they also have abnormally broad shoulders.pic.twitter.com/umL1WdJ7fP
The massive height seen in the ex-Yugoslavia is very strange. In most European groups height seems to increase smoothly as you move north up the first PC of variation, which reaches its northern apex in the tall, blond Latvians and in the other extreme in Sicilians.
Montenegrins and Romanians are fairly close genetically, being much more South European than Old Slavic and yet their difference in height is more than 4 inches. Not only are these people big absolutely, their size is defying a very strong pattern.
My argument here is more speculative than the others, but I think the key factor is the late persistence of the Mediterranean practice of transhumant pastoralism, where herders regularly migrate from warm coastal areas in the summer to highlands in the winter.
High meat consumption, which is characteristic of all the people discussed here, is probably a pre-requisite of large body bulk. But this wouldn’t explain the small arms of Montenegrins and Serbs, and cold stress imposed by the ex Yugoslavia’s very high levels of rainfall would:pic.twitter.com/iW2BcOazNp
Fin. Comments welcome, going to try and do another one of these tomorrow on some of the peculiarities of the Japanese.
