Nabokov and the blues

Nabokov Butterfly Theory Is Vindicated "Nabokov came up with a sweeping hypothesis for the evolution of the butterflies he studied, a group known as the
Polyommatus blues. He envisioned them coming to the New World from Asia over millions of years in a series of waves. Few professional lepidopterists took these ideas seriously during Nabokov’s lifetime. But in the years since his death in 1977, his scientific reputation has grown. And over the past 10 years, a team of scientists has been applying gene-sequencing technology to his hypothesis about how Polyommatus blues evolved. On Tuesday in the Proceedings of the Royal Society of London, they
reported that Nabokov was absolutely right."

and find that climatic conditions in Beringia acted as a decisive filter in determining which taxa crossed into the New World during five separate invasions over the past 11 Myr.
Undoubtedly, whether or not the Bering Strait was frozen solid or not acted as an effective filter to the migration of larger animals. Interesting that subtler changes in the climate of the same region had a commensurate effect on insects.
