Discovery of a new class of vertebrates

The book presents a groundbreaking theory that reclassifies crocodiles as a distinct class, separate from reptiles, birds, and mammals. It explores the evolutionary development of the four-chambered heart in crocodiles, which diverged from the reptilian lineage, while maintaining both systemic arches. This perspective challenges traditional classifications of land vertebrates, suggesting that crocodiles, like birds and mammals, have evolved unique traits that warrant their own classification. The author delves into the anatomical differences and evolutionary pathways that support this conclusion.
