Any evolutionary scenario between land and sea mammals has to explain the different ear and nose structures between the two groups. Let us first consider the ear structure. Like us, land mammals trap sounds from the outside world in the outer ear, amplify them with the bones in the middle ear, and turn them into signals in the inner ear. Marine mammals have no ear. They hear sounds by means of vibration-sensitive receptors in their lower jaws. The crucial point is that any evolution by stages between one perfect aural system to a completely different one is impossible. The transitional phases would not be advantageous. An animal that slowly loses its ability to hear with its ears, but has still not developed the ability to hear through its jaw, is at a disadvantage.
The question of how such a "development" could come about is an insoluble dilemma for evolutionists. The mechanisms evolutionists put forward are mutations and these have never been seen to add unequivocally new and meaningful information to animals' genetic information. It is unreasonable to suggest that the complex hearing system in sea mammals could have emerged as the result of mutations.
In fact, fossils show that no evolution ever happened. The ear system of Pakicetus and Ambulocetus is the same as that in terrestrial mammals. Basilosaurus, which follows these two land mammals in the supposed "evolutionary tree," on the other hand, possesses a typical whale ear. It was a creature that perceived sounds around it not through an outer ear but by vibrations reaching its jaw. And there is no "transitional form" between Basilosaurus' ear and that of Pakicetus and Ambulocetus.
A similar situation applies to the "sliding nose" tale. Evolutionist sources set out three skulls from Pakicetus, Rodhocetus and a grey whale from our own time above one another and claim that these represent an "evolutionary process." Whereas the three fossils' nasal structures, especially those of Rodhocetus and the grey whale are so different that it is impossible to accept them as transitional forms in the same series.
Furthermore, the movement of the nostrils to the forehead would require a "change" in the anatomy of the animals in question, and believing that this could happen as the result of random mutations is nothing but fantasy.
