Darwin’s short-beak enigma solved

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.

Ribs evolved for movement first, then co-opted for breathing

A major transformation in vertebrate evolution was when breathing shifted from the head to the torso in reptiles. But what caused the shift? A study hypothesizes it was driven by locomotion.
