Uriah

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.

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.
