The fossil records constitute the clearest evidence showing us that the scenario suggested by the theory of evolution did not take place.
According to the unscientific supposition behind this theory, every living species has sprung from a predecessor. A previously existing species (evolutionists have yet to offer an explanation on how this species came into existence) turned into something else over time and all species have come into being in this way. In other words, this imaginary transformation took millions of years and proceeded gradually.
If this were the case, innumerable intermediary species should have existed and lived within this long transformation period.
For instance, some half-fish/half-reptiles would have lived in the past, which had acquired some reptilian traits in addition to the fish traits they already had. Or there should have existed some reptile-birds, which acquired some bird traits in addition to the reptilian traits they already had. Since these would be in a transitional phase, they should be disabled, defective, crippled beings. Evolutionists refer to these imaginary creatures, which they believe to have lived in the past, as “transitional forms”.
If such animals ever really existed, there would be millions and even billions of them in number and variety. More importantly, the remains of these strange creatures should be present in the fossil record. In The Origin of Species, Darwin explained:
If my theory be true, numberless intermediate varieties, linking most closely all of the species of the same group together must assuredly have existed… Consequently, evidence of their former existence could be found only amongst fossil remains… (SOURCE)
However, Darwin, having written these lines, was also well aware of the fact that no fossils of these intermediate forms had yet been found. He regarded this as a major difficulty for his theory. That is why, in one chapter of his book titled “Difficulties on Theory,” he wrote:
Firstly, why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion instead of the species being, as we see them, well defined?…. But, as by this theory innumerable transitional forms must have existed, why do we not find them embedded in countless numbers in the crust of the earth?… (SOURCE)
