1) Weight bearing: Marine creatures do not face the problem of having to support their own weight, so their bodily structures are not directed towards such a function. Those living on land, however, expend 40% of their energy just in moving around. Any water dweller about to pass onto dry land needs to develop new muscles and a new skeletal structure to meet that need-but it is impossible for such complex structures to form through random mutations.
Evolutionists imagine the coelacanth and other similar fish to be the ancestors of terrestrial animals because of the bony nature of their fins. They assume that these bones gradually developed into weight-bearing feet. Yet unlike the feet of land dwellers, the bones in a fish's fins are not connected directly to their backbone. This means they cannot perform a weight- bearing function, as do the leg bones in terrestrial animals. Therefore, the claim that these fins slowly evolved into feet is groundless.
2) Heat protection: On land, temperatures can change very fast and within a wide range. A terrestrial animal's metabolism allows it to adapt to these temperature changes in. In the sea, however, temperatures change very slowly, and do not range as widely as on land. A creature accustomed to the sea's even temperatures therefore needs to acquire a protective system appropriate to the temperature swings on land. It would be ridiculous to claim that fish acquired such a system through random mutations as soon as they emerged onto dry land.
3) Use of water: Water is an essential requirement for living things, and on land, its availability is limited. For that reason water, and even moisture, must be used economically. For example, skin must prevent water loss and evaporation, and land dwellers must be able to feel thirst when they need water. Yet underwater creatures have no sense of thirst and their skins are not suited to a dry environment.
4) Kidneys: Due to the abundant water in their environment, marine creatures can immediately filter and expel their bodies' waste products, particularly ammonia. On land, however, water must be used at minimum levels. For that reason these living things have kidneys, thanks to which ammonia is filtered out as urea and stored in the bladder, and the minimum amount of water is used when it is expelled. In addition, there is a need for new systems that enable the kidneys to function. In order for a transition from water to land, creatures without kidneys will need to develop them immediately.
5) Respiratory system: Fish breathe the oxygen dissolved in water through their gills. Out of the water, however, they are unable to survive for more than a few minutes. In order to live on dry land, they need to acquire a pulmonary system.
It is of course impossible for all these physiological changes to take place by chance and all at the same time.
According to the evolutionist scenario, fish first evolved into amphibians. Yet there is no evidence for that scenario: Not a single fossil has been found to show that half-fish, half-amphibian creatures ever existed.
The "transition from water to land" scenario portrayed in many imaginative illustrations like the one above, is based on Lamarckist logic and conflicts even with the theory of evolution's own hypotheses.
Robert L. Carroll, the well-known evolutionist and author of Vertebrate Paleontology and Evolution, admits this, albeit reluctantly:
"We have no intermediate fossils between rhipidistian fish and early amphibians." 2 (See Amphibians.)
The evolutionist paleontologist Barbara J. Stahl wrote a book, Vertebrate History: Problems in Evolution, in which she says:
Although the relationship of the rhipidistians to the amphibians will be discussed in greater detail in the next chapter, it should be said here that none of the known fishes is thought to be directly ancestral to the earliest land vertebrates. Most of them lived after the first amphibians appeared, and those that came before show no evidence of developing the stout limbs and ribs that characterized the primitive tetrapods. 3
