I want to present some paragraphs for discussion from the website I linked:
Darwinism Refuted.com
Those of you who may have some expert knowledge of the subject are encouraged to speak to these critiques of Darwin's theory. Here is a an example:
[quote] In order for the fossil record to shed any light on the subject, we shall have to compare the hypotheses of the theory of evolution with fossil discoveries.
According to the theory of evolution, every species has emerged from a predecessor. One species which existed previously turned into something else over time, and all species have come into being in this way. According to the theory, this transformation proceeds gradually over millions of years.
If this were the case, then innumerable intermediate species should have lived during the immense period of time when these transformations were supposedly occurring. For instance, there should have lived in the past some half-fish/half-reptile creatures which had acquired some reptilian traits in addition to the fish traits they already had. Or there should have existed some reptile/bird creatures, which had acquired some avian traits in addition to the reptilian traits they already possessed. Evolutionists refer to these imaginary creatures, which they believe to have lived in the past, as "transitional forms."
If such animals had really existed, there would have been millions, even billions, of them. More importantly, the remains of these creatures should be present in the fossil record. The number of these transitional forms should have been even greater than that of present animal species, and their remains should be found all over the world. In The Origin of Species, Darwin accepted this fact and 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.39
Even Darwin himself was aware of the absence of such transitional forms. He hoped that they would be found in the future. Despite his optimism, he realized that these missing intermediate forms were the biggest stumbling-block for his theory. That is why he wrote the following in the chapter of the The Origin of Species entitled "Difficulties on Theory":
…Why, if species have descended from other species by 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?… But in the intermediate region, having intermediate conditions of life, why do we not now find closely-linking intermediate varieties? This difficulty for a long time quite confounded me.40
The only explanation Darwin could come up with to counter this objection was the argument that the fossil record uncovered so far was inadequate. He asserted that when the fossil record had been studied in detail, the missing links would be found.[>quote]
