THE ORIGIN OF THE MARINE MAMMALS AND NATURAL SELECTION
Whales and dolphins are classified as mammals because, just like terrestrial mammals, they give live birth, suckle their young, breathe with lungs and are warm-blooded. But the origin of marine mammals is one of the most difficult questions facing evolutionists.
Most evolutionist sources describe how the land-dwelling ancestors of seagoing mammals evolved in such a way as to move over to a marine environment as the result of a lengthy evolutionary process. According to this claim, marine mammals followed a path diametrically opposed to the transition from water to dry land, returning to a marine environment as the result of a second process of evolution. However, this theory is based on no paleontological evidence-and is also logically inconsistent.
Mammals are regarded as the top rung of the evolutionary ladder. That being so, the question arises of how these creatures moved back to a marine environment. A subsequent question is that of how they adapted to that environment even better than fish. Dolphins, which are mammals and thus possess lungs, are even better adapted to their environment than fish, which breathe in water.
It is perfectly obvious that the imaginary evolution of marine mammals cannot be explained in terms of mutations and natural selection. One article published in GEO magazine refers to the origin of the blue whale, stating the despairing position of Darwinism on the subject:
Like blue whales, the bodily structures and organs of other mammals living in the sea also resemble those of fish. Their skeletons also bear similarities to those of fish. In whales, the rear limbs that we can refer to as legs exhibited a reverse development and did not reach full growth Yet there is not the slightest information about these animals' form changes. We have to assume that the return to the sea took place not through a long-term, slow transition as claimed by Darwinism, but in momentary leaps. Paleontologists today lack sufficient information as regards which mammal species whales are evolved from. 1
It's difficult indeed to imagine how, as the result of any evolutionary process, a small terrestrial mammal could become a whale 30 meters (98 feet) long and weighing 60 tons.. On this subject, all that Darwinists are able to do is, as in the account published in National Geographic magazine cited below, to exercise their imaginations:
The whale's ascendancy to sovereign size apparently began sixty million years ago when hairy, four-legged mammals, in search of food or sanctuary, ventured into water. As eons passed, changes slowly occurred. Hind legs disappeared, front legs changed into flippers, hair gave way to a thick smooth blanket of blubber, nostrils moved to the top of the head, the tail broadened into flukes, and in the buoyant water world the body became enormous. 2
Bearing in mind the adaptations that a mammal, using lungs to breathe with, would have to undergo in order to thrive in a marine environment, it can be seen that even the word impossible fails to do justice to the situation. The absence of even one rung of the ladder in such an evolutionary transition would deny the animal the ability to survive, and bring the evolutionary process to an end.
Marine Mammals and Their Unique Structures
The adaptations that marine animals would have to undergo during a transition to a water environment can be enumerated as follows:
1. Water Conservation. Marine mammals are unable to meet their water requirements in the same way as fish do, by using salt water. They need fresh water in order to live. Although the water sources of marine animals are not well known, it is thought that they meet a large part of their water requirements by eating creatures that contain up to one-third as much salt as exists in the ocean. For marine mammals, it is of great importance to conserve as much fresh water as possible. For that reason, they possess water conservation mechanisms like that seen in camels.
Like camels, marine mammals do not sweat. Their kidneys provide water for them by concentrating urine in a much better way than in humans, thus reducing water loss to a minimum. Water conservation reveals itself in even the smallest details. For example, the mother whale feeds her young with milk of a dense consistency like that of cottage cheese, and which is some tens of times more fatty than human milk.
