As any primatologist will tell you, humans are just about the only primates with white sclera—our eyes have whites. Check the gaze of a monkey or ape. See there? Dark sclera. Human eyes are also strikingly elongated on a horizontal axis. Scientists speculate that this was an evolutionary adaptation that made it easier for one Home sapiens to direct or follow the gaze of another, important in social interaction and cooperative hunter-gatherer activity.
There's a region around Lake Winnipeg in Manitoba called New Iceland. It takes its name from the influx of Icelandic immigrants in the late 19th century. There are some striking things about this story. One, the first Icelanders to show in Canada were Mormons. I didn't know there were Icelandic Mormons, at least in any number. Two, as the story goes, the Mormons had left Iceland's Westman Islands; in 1627, three shiploads of Barbary pirates took over the islands in what is now known as "the Turkish abductions." (I think every place should have an incident known as the Turkish abductions, just because.) Three, for 45 years starting in 1870, nearly a fourth of Iceland's population up and moved to Canada, escaping a bad economy and an obstreperous volcano. In 1875, a large contingent headed west to Gimli, Manitoba. A fourth of the population; that's a lot, and Manitoba now has the largest Icelandic community outside of Iceland.
