Question

Quizplus · Accepted Answer

Palaeognaths, which include birds like ostriches and emus, are generally characterized by their limited ability to fly or complete flightlessness, contrasting with neognaths that encompass a wide range of flying birds. Choices B, C, D, and E are incorrect as they do not accurately describe the differences between palaeognaths and neognaths: all birds, including both groups, have feathers; size varies widely within both groups; all modern birds are oviparous; and neither group has true teeth in the modern sense.
