Fossils. Reptiles and mammals

Description

This program presents fossil evidence for the evolution of reptiles and amphibians; explains the reasoning processes scientists must use when no direct evidence is available for examination; illustrates field techniques for collecting fragile fossils for transportation to the laboratory, where examination can take place under controlled conditions; and traces the evolution of some modern mammals back through time. After viewing the program, students should know which major features distinguish amphibians from reptiles, when and for how long reptiles were the dominant land animals and by whom they were replaced, and recognize the feature in the fossil remains of land reptiles that may indicate that they gave rise to mammals.
