Birds
The group of fish that gave rise to terrestrial vertebrates is known as lobe-finned fish. These fish had fleshy fins with bony supports that eventually evolved into limbs capable of supporting the animals on land. The transition from water to land occurred during the Devonian period, around 360 million years ago.
Both mammals and birds are descended from reptiles.
the dinosaurs became extinct because the was kill of there family
The major difference between vertebrates and invertebrates is that vertebrates have a back bone and invertebrates don't
What are you talking about? Gynosperms are plants (pines, for instance) :S They're related to all living things, but we're not exactly very close relatives with them.
vertebrates have backbones while invertebrates do not.
Fish is aquatic vertebrates while other vertebrates are which animal have backbone.
The two major groups of dinosaurs are the Saurischia (lizard-hipped dinosaurs) and the Ornithischia (bird-hipped dinosaurs). These groups are distinguished by differences in their pelvic bone structure.
Vertebrates and Invertebrates
Vertebrates and invertebrates.
scientist have been able to infer the relationships between the major groups of vertebrates by bones
The two major groups of animal classification are vertebrates and invertebrates. Vertebrates have a backbone or spine, while invertebrates do not. Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish, while invertebrates include insects, arachnids, mollusks, and annelids.
