I knew I was going to have to get my hands dirty when I started this, so here goes.
First of all, the horse series. Long believed to be evidence of evolution, it has been dismissed by professional evolutionists, although in schools it is still shone as proof. Eohippus, the dawn horse, is not at all related to horses and is actually a type of rock rabbit which is still alive in Africa today and was first classified in Hyracotherium with the rock rabbit. Another flaw is that the ribs in the linked species are constantly changing number. In Eohippus, the rib count is 18. Orohippus has fifteen pairs, Pliohippus has 19, and Equus has 18. This shifting of rib number is a strong indication that the series is not at all a series but merely an unrelated collection. Yet another fault is the location of these creatures. One was found in India, some in Europe, and most in the United States. The final blow is that specimens of Equus, the modern horse, is found alongside and even below it's supposed ancestors; that would mean that the "modern horse" is older than it's ancestors!
The whale is another problem. According to Evolution, the whale evolved from a land creature. The transition from land to water prevents the possiblilty. The animal would first have begin to evolve flippers and flukes, but this could not survive, as a creature with partially formed flukes and flippers would be unable to walk on land and would have spinal muscles too weak to escape preditors in the water. It would have drowned, been caught by predators, or starved to death.
