Solved: Charles Darwin’s Mysterious Short-Beak Enigma

Recommended Posts

Manwon Lender

Charles Darwin was obsessed with domestic pigeons. He thought they held the secrets of selection in their beaks. Free from the bonds of natural selection, the 350-plus breeds of domestic pigeons have beaks of all shapes and sizes within a single species (Columba livia).

In a new study, biologists from the University of Utah discovered that a mutation in the ROR2 gene is linked to beak size reduction in numerous breeds of domestic pigeons. Surprisingly, mutations in ROR2 also underlie a human disorder called Robinow syndrome.
