Vertebrates
Development and Diversity
This DVD introduces the members of vertebrates group existing today, illustrated by various examples. The phyloge- netic development, which started in the primeval oceans, is shown in detail by means of homologous skeleton structures. The variations in the body’s basic structure in adaptation to the vertebrates’ respective needs, which resulted in today’s situation with vertebrates living in water, on land and in the air, are demonstrated by means of extant representatives of the class. The vertebrates group encompasses cartilage and bony fishes, amphibians, reptiles, birds and mammals. The modifications of those skeletal elements serving locomotion, from the fins of the fish to the wing span of the birds and the hands of mammals, are shown. This DVD is suitable for the topic of vertebrates for younger pupils or as a contribution to the topic of evolution illustrated by means of the development of vertebrates.
