Answer Details

The best evidence of the relationship between living organisms and their extinct relatives can be obtained from paleontology. Paleontology is the study of fossils, which are the remains or traces of ancient organisms that are preserved in rock. By studying fossils, scientists can learn about the anatomy, behavior, and evolution of extinct species and compare them to living organisms. Comparative anatomy and physiology are also useful for understanding relationships between organisms, but they only provide information about living species. Comparative anatomy involves comparing the physical structures of different organisms, while comparative physiology looks at the functions of those structures. Embryology focuses on the development of organisms from the fertilized egg stage to birth or hatching. While embryology can provide insight into evolutionary relationships, it also has limitations, as organisms with very different adult forms can have very similar embryos. In contrast, paleontology provides a unique window into the evolutionary history of life on Earth by allowing us to observe extinct species and compare them with living ones. Through paleontology, scientists can construct detailed evolutionary trees that show how different groups of organisms are related to each other and how they have changed over time.
