Paleontologists proposed that whales had evolved from land mammals with legs, and therefore, in an example of its predictive power, the theory of evolution forecast that legs would be found on fossilized whales. In recent years the evolution of whales from now extinct land mammals has become well documented through newly found fossils from the Eocene epoch, about 50 million years ago (Wong 2002). The fossilized whales contain well-defined feet and legs. In modern adult whales, the front legs have evolved into flippers and the rear legs have shrunk so that no visible appendages appear. Hindlimbs still appear in the fetuses of some modern whales but disappear by adulthood. Externally invisible, vestigial diminished pelvic bones occur in modern adult whales. Evolution accounts for these useless vestigial elements as leftovers in the development of whales from land mammals, but they remain unaccounted for by Intelligent Design.
Got any pictures of these ancient whales (their fossils) and their modern (skeletal) counterparts, so we can see what the author is talking about here?
