Like many, I first learned about Iceland when studying the Vikings in elementary school. As an island nation in the North Atlantic Ocean, today I don’t think of the Vikings, but genetics is my prime thought. Although there is some disagreement on the matter, some consider Icelandic genes to be more homogeneous (less diverse) than other lands. Given the mobility of humans today and because isolation is one important aspect of evolution, the thought is intriguing.
Being that we enjoy cruising, cruise ships do go to Iceland … and my wife has mentioned an interest in visiting the mountainous place with hot springs.
