How evolution sculpts the facial shapes of birds and mammals
Shapes of beaks and snouts come in an extraordinary range of forms, reflecting adaptations to different lifestyles and environments. Yet beneath this diversity lies a paradox: across birds and mammals, faces are built using deeply conserved developmental programs. So how does evolution generate such...

Shapes of beaks and snouts come in an extraordinary range of forms, reflecting adaptations to different lifestyles and environments. Yet beneath this diversity lies a paradox: across birds and mammals, faces are built using deeply conserved developmental programs. So how does evolution generate such striking differences without reinventing the underlying machinery?
