Based on a analysis on a fossil found in a Pakistani dessert, early whales have been discovered to have given birth on land. The fossil was categorized to ancient amphibious whales named Archaeoceti. Philip Gingerich was intrigued by the features and body structure of the fossil. The head-first position of the fetus generally gave away the fact that is was a land mammal. The fossil was said to be classified as family to another early whale species, Rodhocetus and Artiocetus. Fossils have indeed helped evaluate whale evolution, but there yet to learn. Paleontologists have proven that whale have evolved through 3 stages to arrive at the modern whale we see today. whales started with a backbone and hind legs but then they began consistently losing them. a recent adult whale fossil has proven that the fetus had fully grown teeth getting the baby ready to support it self after birth. Hopefully paleontologists willy finally discover the whale evolution.
