The Ancestry of Modern Amphibia: A Review of the Evidence

"The Ancestry of Modern Amphibia: A Review of the Evidence" by Theodore H. Eaton, Jr. is a scientific exploration into the family history of today's frogs, salamanders, and caecilians. The publication offers a detailed look at the ancient species that might be their relatives, using fossil evidence to connect them. The author examines the bones, ear structures, and growth patterns of different amphibian types, both old and new. His work compares frogs and salamanders to see if they share a common ancestor from the Paleozoic era. Eaton presents a case that modern amphibians developed through changes that helped them live in both water and on land, backing everything up with facts about their physical forms and how they grow from embryos.
