Exempel på hur man kan använda RATITES i en mening

• Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species.
• Thus, living birds were divided into carinatae (keeled) and ratites (from ratis, "raft", referring to the flatness of the sternum).
• Approximately the size of a domestic chicken, kiwi are the smallest ratites (which also include ostriches, emus, rheas, cassowaries and the extinct elephant birds and moa).
• They are distantly related to the African ostriches and Australia's emu (the largest and second-largest living ratites, respectively), with rheas placing just behind the emu in height and overall size.
• The Palaeognathae or "old jaws" is one of the two superorders recognized within the taxonomic class Aves and consist of the ratites and tinamous.
• Tinamous are the only living group of palaeognaths able to fly, and were traditionally regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation as most closely related to the extinct moa of New Zealand, implying flightlessness emerged among ratites multiple times.
• They are not closely related to ratites such as emus, and their closest living relatives are thought to be fowl.
• Elephant birds are palaeognaths (whose flightless representatives are often known as ratites), and their closest living relatives are kiwi (found only in New Zealand), suggesting that ratites did not diversify by vicariance during the breakup of Gondwana but instead convergently evolved flightlessness from ancestors that dispersed more recently by flying.
• All tinamous are in the family Tinamidae, and in the larger scheme are also palaeognaths, a group that includes the more widely known flightless ratites such as ostriches and emus.
• There are over 60 extant species, including the well-known ratites (ostriches, emus, cassowaries, rheas, and kiwis) and penguins.
• Ostriches are of the genus Struthio in the order Struthioniformes, part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that includes the emus, rheas, cassowaries, kiwis and the extinct elephant birds and moas.
• The sternum, for example, is elongated and deeply keeled for an enlarged pectoralis muscle, as it is in neognathous birds and volant ratites.
• Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two orders: Carinatae (from carina, "keel"), having a pronounced keel; and ratites (from ratis, "raft"referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely.
• Tinamous are the only members from their infraclass that aren't ratites, and can even fly, albeit poorly.
• All tinamous are usually treated in a single family (Tinamidae) and, contrary to traditional classifications, they are embedded within the group known as ratites, most closely related to the extinct moa of New Zealand.
• These field exhibits, divided into regions such as Africa, Asia and the Americas, mainly feature the park’s ungulate herds and larger hoofed mammals (including rhinos, hippos, giraffes and elephants), as well as larger species of birds, including cranes and ratites.
• They are distantly related to the ratites (order Struthioniformes) which includes the rheas, emu, and kiwis.
• For many years it was thought that dromornithids were related to ratites, such as emus, cassowaries, rheas and ostriches.
• They are distantly related to the ratites (order Struthioniformes), which includes the rheas, emus, and kiwis.
• Palaeognathae contains five extant branches of flightless lineages (plus two extinct clades), termed ratites, and one flying lineage, the Neotropic tinamous.
