When the Cambrian fossils are examined, it is seen that the major phyla and classes of animals suddenly appear fully developed in the Cambrian strata with no ancestral linage leading up to the many different phyla and classes. In other word, you don't see the speciation of animals producing different genera, then the continuation of morphological evolution producing animals that can be divided into different families and then orders. Instead, as mentioned above, the Cambrian geological record contains fossilized animals that are very diverse in the hierarchy of the taxonomical rank and show no sign of a slow divergence from a common ancestor. The mutations are not shown to add up.
... The question becomes:
Why do the major phyla and classes of animals suddenly appear fully developed in the Cambrian fossils with no ancestral linage leading up to the phyla and classes that are found fossilized there as the T.O.E. predict they should?
Instead, a major problem for evolutionism is recognized. The geological record has fossilized animals that are very diverse in the hierarchy of the taxonomical rank and show no sign of a slow divergence from a common ancestor. The animals found in the Cambrian strata are already divided into different phyla and classes.
Suddenly appear.
@EarlyActs said that no creatures would “suddenly appear” complex, and I asked what suddenly means. According to
@CrowCross here, referring to the early Cambrian radiation, it means roughly 30 million years. (Subsequent taxonomic elaboration consumed another 20–30 million years, from middle to late Cambrian. All told, the Cambrian spanned ~55 million years.)
In that case, the claim is false. New, morphologically diverse species do appear after tens of millions of years. For example, the humpback whale and the hippopotamus—certainly different species and very diverse morphologically—trace to a lineage split that occurred within that kind of timeframe.
No ancestral lineage.
This is incorrect. The Cambrian (which spanned ~50 million years) did not emerge in isolation. It was preceded by the Ediacaran period (which was nearly twice as long); in that period we find multicellular organisms, early soft-body bilaterians, trace fossils, and bauplans that gave rise to the Cambrian diversification. These are precisely what ancestry before major diversification would look like, ancestors with limited preservable hard parts and simpler morphologies.
There are two facts which drive the illusion of “suddenness.” The first is
taphonomy. Early ancestors were small, soft-bodied, and poorly mineralized. Fossilization probability was extremely low. Expecting a smooth, continuous sequence is hopelessly naïve. The second is
geological resolution. The Cambrian “explosion” spans ~30 million years. That is sudden in geological terms, but not in evolutionary terms, and certainly not in ordinary terms. That “sudden” appearance spanned a very, very long time. For some perspective, 30 million years ago there were no humans, no hominins, not even hominoids (apes). Entire mammalian radiations unfolded within that interval. It is only sudden in a geologic sense.
It is intellectually careless to imagine that evolution should be visible generation by generation in rock layers. Fossilization just won’t produce that. And a lack of fossil continuity isn’t evidence of no ancestors; it is evidence of exactly that preservation bottleneck, something especially predicted of the Ediacaran period and its soft-bodied creatures. The record we possess is entirely consistent with gradual descent operating over epochs of time, constrained by the limits of fossil preservation.
Speciation of animals producing different genera, etc.
This claim misunderstands how evolution proceeds. It does not unfold as a tidy ladder of species, genus, family, order, class, and phylum recorded sequentially in the rocks. Taxonomic ranks are human labeling conventions, not evolutionary stages. Evolution doesn’t climb the taxonomic hierarchy. It doesn’t generate genera first, then families, then orders as if building a corporate organization chart. That expectation itself is the mistake. Evolution produces branching divergence, often with early explosions of morphological disparity followed by later diversification within established body plans—a pattern Darwin already recognized in principle which was later formalized as punctuated equilibrium by Gould and Eldredge. (See
my post in another thread which addresses this in a bit more detail, with quotes and citations.)
The theory belonging to evolutionism tells us that all life evolved from a common ancestor.
I don’t know what “the theory belonging to evolutionism” is supposed to be. It sounds like a deliberate attempt to misrepresent, which would be a violation of the rules. There is nothing stopping you from representing the opposing view accurately and honestly. For example, you could have simply said, “The theory of evolution tells us that all life evolved from a common ancestor.”
My response to that? “Correct.”
This hypothesis is taught as fact in our schools and even presented from time to time on this forum as the truth.
This is a category error. You just switched from “theory” to “hypothesis.” I hope this wasn’t deliberate, that you’re using these terms interchangeably simply because you don’t know the difference between these categories—because if it was deliberate then it was a violation of the rules.
In science, a
law is a generalization about empirical data that seeks to describe the regular and consistent patterns and relationships that are found. But these are
descriptions, which are not
explanations. That is the role of a
theory, a concise unifying conceptual structure that ties together and explains observed and predicted empirical phenomena (causes, forces, etc.) and their relationships. Theories also encompass and integrate many different
hypotheses, which are
limited explanations of more narrow sets of phenomena. [1] Here is an example that should help to illustrate the difference between each term and their relationships to one another: A
hypothesis about graviton particles might serve a general
theory of gravitation proposed to explain the
law of gravity.
But is it true? Or just another lie from the camps of evolutionism which have been kept secret?
The theory of evolution is true in the same sense that the heliocentric theory is true. We casually refer to our sun-centered planetary system as a fact, even though it’s actually just a theory. (The solar system as a whole has never been observed.) When a theory has withstood so many thousands of empirical tests and remains unfalsified, it is
practically a fact even if
technically it isn't.
