A fishy tale: transition from water to land

Evolutionists assume that the sea invertebrates thatappear in the
Cambrian stratum somehow evolved into fish in tens of million years.
However, just as Cambrian invertebrates have no ancestors, there are no
transitional links indicating that an evolution occurred between these
invertebrates and fish. It should be noted that invertebrates and fish
have enormous structuraldifferences. Invertebrateshave hard tissues
outsidetheir bodies, whereas fish are vertebrates that have hard tissues
inside. Such an enormous "evolution" event ought to have been supported
by billions of transitional forms displaying the intervening changes.
Evolutionists have been digging fossil strata for about 140 years
looking for these hypothetical forms, they have found millions of
invertebrate fossils and millions of fishfossils; yet nobody has ever
found even one thatis midway between them.
An evolutionist paleontologist, Gerald T. Todd admits this fact in an
article titled "Evolution of the Lung and the Origin of Bony Fishes" :
"All three subdivisions of the bony fishes first appear in the fossil
record at approximately the same time. They are already widely divergent
morphologically, and they are heavily armored.How did they originate?
What allowed them to diverge so widely? How did they all come to have
heavy armor? And why is there no trace of earlier, intermediate forms?"
The evolutionary scenario goes one step further and argues that fish
evolved from invertebrates, then transformed into amphibians. But this
scenario also lacks evidence. There is not even a single fossil
verifying that a half-fish/half-amphibian creature has ever existed.This
fact is confirmed (albeit reluctantly) by a well-known evolutionist
authority, Robert L. Carroll, who is the authorof Vertebrate
Paleontology and Evolution as: "We have no intermediate fossils between
rhipidistian fish(his favourite 'ancestors' of tetrapods) and early
amphibians." Two evolutionist paleontologists, Colbert and Morales,
comment onthe three basic classes of amphibians – frogs, salamanders,
and caecilians:
"There is no evidence of any Paleozoic amphibian combining the
characteristics that would be expected in a single common ancestor. The
oldest known frogs, salamanders and caecilians are very similarto their
living descendants."
Until about fifty years ago, evolutionists thought that such a creature
indeed existed. This fish, called a Coelacanth, which was estimated to
be 410 million years of age, was put forward as a transitional form with
a primitive lung, a developed brain, a digestive and a circulatory
system ready to function on land and even a primitive walking mechanism.
These anatomical interpretations were accepted as undisputed truth among
scientific circles until the end of the 1930s. The Coelacanthwas
presented as a genuine transitional form that proved the evolutionary
transition from water to land.
However, on December 22, 1938, a very interesting discovery wasmade in
the Indian Ocean . A living member of the Coelacanth family, previously
presented as atransitional from that had become extinct 70 million years
ago, was caught! The discovery of a "living" prototype of Coelacanth
undoubtedly gave evolutionists a severe shock. The evolutionist
paleontologist J. L.B. Smith said that he could not have been more
surprised if he had come across a living dinosaur. In the years to come,
200 Coelacanths were caught many times in different parts of the world.
Living Coelacanths revealed how far the evolutionists could go in making
up their imaginary scenarios. Contrary to claims, Coelacanths had
neither a primitive lung nor a large brain. The organ that evolutionist
researchers proposed as a primitive lung turned out to be nothing but a
lipid pouch. Furthermore,the Coelacanth, which was introduced as "a
reptile candidate getting prepared to pass from sea to land," was in
reality a fish that lived in the depths of oceans and never approached a
distance of less than 180 meters from the surface.
Why Transition From Water to Land is Impossible
Evolutionists claim that one day, a species dwelling in water somehow
stepped onto land and was transformed into a land-dwelling species.
There are a number of obvious facts that render such a transition
impossible:
1. Weight-bearing: Sea-dwelling creatures have no problem in bearing
their own weight in the sea.
However, most land-dwelling creatures consume 40 percent of their energy
just in carrying their bodies around. Creatures making the transition
from water to land would, at the same time, have had to develop
newmuscular and skeletal systems (!) to meet this energy need, and this
could not have come about by chance mutations.
2. Heat Retention: On land, the temperature can change quickly and
fluctuates over a wide range. Land-dwelling creatures possess a physical
mechanism that can withstand such great temperature changes. However, in
the sea, the temperature changes slowly and within a narrower range. A
living organism with a body system regulated according to the
constantsea temperature, would need to acquire a protective system to
ensure minimum harm from the temperature changes on land. It is
preposterous to claim that fish acquired such a system by random
mutations as soon as theystepped onto land.
3. Water: Since it is essential for metabolism, water needs to be used
economically due to its relative scarcity on land. For instance, the
skin has to be able to permit a certain amount of water loss, while
preventing excessive evaporation simultaneously. That is why
land-dwelling creatures experience thirst, something the sea-dwelling
creatures do not do. For this reason, the skin of sea-dwelling animals
is not suitable for a non-aquatic habitat.
4. Kidneys: Sea-dwelling organisms discharge waste materials, especially
ammonia, by means of their aquatic environment. On land, water has to be
used economically. This is why these living beings have a complex
excretory system comprising the kidneys and other organs. Thanks to the
kidneys, ammonia is stored by being converted into urea and the minimum
amount of water is used during its excretion. In addition, new systems
are needed to support the kidney's functioning. In short, for the
passage of organismsfrom water to land to have occurred, living things
without a kidney would have had to develop a kidney system all at once.
5. Respiratory system: Fish "breathe" by taking in oxygen dissolved in
water that they pass through their gills. They cannot live for more
thana few minutes out of water. In order to surviveon land, they would
haveto acquire a perfect lung system all of a sudden.
It is most certainly impossible that all these dramatic physiological
changes could have happened in the same organism at the same time, and
all by chance.
