Black Death casts a genetic shadow over England – health – 01 August 2007 – New Scientist
The Black Death continues to cast a shadow across England. Although the modern English population is more cosmopolitan than ever, the plagues known as the Black Death killed so many people in the Middle Ages that, to this day, genetic diversity is lower in England than it was in the 11th century, according to a new analysis.
千年前と今の英国人の遺伝的多様性を比べると、千年前の方が多様だった。その間、黒死病で若い人が死んじゃったせいじゃないかと。遺伝的な多様性は、かくももろいものか。
