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.
Biologists drove the divergence of different-sized feather lice from a single population. In four years the evolved lice had trouble mating with each other, a sign of speciation and they caught it on tape.
U researchers discover the gene that drives diverse patterns on pigeon wings has unexpected links to human blindness.
