Please!
This is hogwash.
'Gaps of 20,000 to 80,000 years' with no resultant fossil record?
What did they do? Turn to dust.
Even the species sited are not consistant in the 'theoretical evolutionary cyle'.
The socalled 'proof' is nothing more than a hyposthesis of what they 'think' has happened between specie manisfestations and they even admit that:
"Species-to-species transitions are even harder to document. To demonstrate anything about how a species arose, whether it arose gradually or suddenly, you need exceptionally complete strata, with many dead animals buried under constant, rapid sedimentation. This is rare for terrestrial animals."
And even the ones discovered can not be considered 'conclusive' based on the 'gaps' in the fossil records.
Millions of transitional forms If the evolution view is correct then millions of transitional forms once existed for each lineage, but should we expect to find them in the fossil record as Dr. Gish and Gary Parker claim? Consider the evolution of the modern horse from eohippus, which is thought to have taken about 60 million years. If we assume a generation time of 3 years, that's 20 million generations. Let us further assume that it takes 1 foot of sediment to bury a horse (probably not enough for the larger more recent horses, but more than enough for the dog-sized early ancestors, so 1 foot is a reasonable average). For a really complete series of transitional forms, we would require at least 1 specimen from each generation. But, if every three years, a river flood buries one horse or horse ancestor under 1 foot of sediment, that's 20 million feet of sediment! Which translates into 3,788 miles of sediments, a figure almost equal to the radius of the earth! Even if erosion and mountain building went on at such a rapid pace, we would rapidly exhaust the supply of rock; and we've only considered the Tertiary Period! One could endlessly modify the above simpleminded assumptions to make the calculations more realistic and perhaps reduce somewhat the amount of sediments required, but the fundamental point remains. To bury and fossilize millions of different transitional forms (from millions of different time horizons) requires millions of feet of sediments. The total thickness of the Tertiary sediments in western North America that contain the fossil equids is a bit under 10,000 feet. Coincidently, G. G. Simpson reports that there are about 10,000 or more equid fossils, but most are fragments, especially teeth; there are less than 100 complete skeletons. And these are not from equidistant time horizons, nor from the entire spacial range of the horses in North America, South America and Eurasia. For example there are no Eocene deposits from the Great Plains area, and those from the other periods present a much smaller total thickness (about 2000 feet.) Yet, as fossil records go, this is an amazingly good one and Simpson considers that these specimens provide a sufficiently complete record with only one or two small gaps. Similar arguments would apply to any other lineage and geological time period. There's no way we could expect anywhere near a complete fossil record of any lineage. At best it can only be fragmentary. Although many millions of transitional forms existed, we cannot expect any but a tiny fraction to have been preserved. Contrary to Dr. Gish's assertion, many in that tiny fraction have been found and are documented in the paleontological literature. (See references listed under movie 4).
Ah, quote mining. The last refuge of those without real arguments.
