Ratites & Tinamous
~60 species
Ancient-jawed birds including the large flightless ratites (ostriches, emus, cassowaries) and the flying tinamous. Among the most primitive living birds.
💡Despite being spread across southern continents, DNA shows ratites descend from flying ancestors — they independently lost flight multiple times.
