Lolita author Vladimir Nabokov has been posthumously proved right over his roundly criticised evolution theory that a type of butterfly migrated from Asia to the New World over a period of millions of years. His controversial evolution theory related to a group of butterfly species known as Polyommatus blues, which he postulated had come in five waves from Siberia, across the Bering Strait to Alaska and then south as far as Chile.
Nabokov died 1977 but his theory has now been tested by butterfly experts who ventured into the Andes to collect Polyommatus blues and retrieve their DNA. They then used gene sequencing technology to establish that Nabokov was right. In a study published in the Proceedings of the Royal Society they concluded that the Bering Strait "served as a biological corridor for the dispersal of these insects from Asia into the New World".
