Мы не знаем. Но если тенденции, выявленные у исландцев, действуют и в других странах (а это почти наверняка так) и если все это будет продолжаться еще несколько веков, то генетическая деградация станет для человечества серьезной проблемой. Чтобы ей противостоять, необходимо побыстрее развивать науку вообще и эволюционную биологию в частности — пока еще есть кому. Разумеется (и к счастью), сегодня речь уже не может идти о варварских методах искусственного отбора, обсуждавшихся основоположниками евгеники. Но есть смысл думать о разработке высокотехнологичных и гуманных методов коррекции неблагоприятных эволюционных тенденций. В том числе — методов, связанных с отбором гамет или ранних эмбрионов, генной терапией и генной инженерией.
