| 1. | Generally speaking, triploblastic organisms belong to the Bilateria subregnum.
|
| 2. | Genetic studies have considerably changed our understanding of the relationships within the Bilateria.
|
| 3. | Three of these subclades occur only in Bilateria ( all but Cnidops ).
|
| 4. | In bilateria, there are many methods of swimming.
|
| 5. | The bilateria are a major group of animals, including the majority of ctenophores.
|
| 6. | The hypothetical most recent common ancestor of all bilateria is termed the " Urbilaterian ".
|
| 7. | They developed from other members of the Bilateria and exhibit bilateral symmetry in their larval stage.
|
| 8. | Triploblastic organisms generally possess bilateral symmetry, which is where the clade Bilateria takes its name.
|
| 9. | A second wave of neurogenesis occurred after the divergence of coelenterata in the common ancestor of bilateria.
|
| 10. | These were originally considered some of the most primitive Bilateria, but it now appears they developed from more complex ancestors.
