"SHOOT" magazine placed it on their Top 10 list for Summer 2008. First broadcast in June 2008, it depicts three flightless birds—a penguin, a chicken, and an emu—being taken hang-gliding (the chicken and the penguin are shown wearing harnesses strapped to the chest of the glider pilots; the emu's harness
Flightless bird the lineage. This indicates that the distinctive flightless nature of ratites is the result of convergent evolution. Two key differences between flying and flightless birds are the smaller wing bones of flightless birds and the absent (or greatly reduced) keel on their breastbone. (The keel anchors muscles needed for wing movement.) Adapting to a cursorial lifestyle causes two inverse morphological changes to occur in the skeleto-muscular system: the pectoral apparatus used to power flight is paedorphically reduced while peramorphosis leads to enlargement of the pelvic girdle for running. Repeated selection for cursorial traits across ratites suggests these adaptions comprise a
