Walking Whales 

WALKING WHALES LIE; Pakicetus was a wolf like mammal. It had a bone in it's inner ear called an "involucrum" that resembled something found in whales. It was fully terrestrial (lived it's entire life on land) and looked nothing like a whale but neo-Darwinist, desperate for a whale ancestor, tagged it Pakicetus or "Pakistani whale". Ambulocetus, Maiacetus, Kuchicetus and Rodhocetus were extinct variations of sea lions or otters. They were amphibious (lived part of their lives on land and part in the water). They used their hind legs and tail for swimming and their four limbs for walking on land.
Basilosaurus and Dorudon were extinct whales that were fully aquatic ( lived their entire lives in the water).
Land and amphibious mammals have nostrils for breathing on the front of their heads. Whales have a blowhole on the top of their bodies to breath.
The blowhole of a whale is surrounded by thick muscular “lips” that keep the hole tightly closed except when the animal makes a deliberate effort to open it at the surface. Total submersion thus takes less effort for whales than for animals that must actively exclude water from their air passages. Coming onto land is not a natural act for a whale; beached whales die if they're not quickly helped back in the water.
Land and amphibious mammals use four legs-tail assisted for amphibians while in water-to move around in their environment. Whales use a fluke to move around in their environment. Land and amphibian mammals can survive without the tip of their tail. Whales can't survive without it.
Flukes are flat horizontal lobes at the ends of their tails. Fluke movements are coordinated by a complex system of long, powerful tendons connecting them to specialized muscles in the tail.
These are a few of the myriad of changes they would have to undergo. For neo-Darwinist it would take hundreds of millions of random mutations (random variations for traditional Darwinist), to compel a fully terrestrial mammal to turn into a fully aquatic mammal.
The biggest problem for the "walking whales" is the empirical evidence-Darwinist refuse to acknowledge--of the fossil record. It's all but complete. Paleontologist have not discovered the fossils of innumerable transitional intermediates, falling between and linking land mammals and aquatic mammals. There are six--presumed intermediates- in the Smithsonian. All the natural history museums in the world should be overflowing with actual intermediates.
With enough imagination anyone can invent a story about how land mammals evolved into whales. But an imaginative story isn't empirical science.
