Precambrian rabbits—death knell for evolution?

Evolutionists typically make a big deal of the fossil record, citing it as powerful evidence for evolution. However, we have pointed out numerous cases of out-of-place fossils, and shown how they do serious damage to the notion that the fossils provide a nice and orderly record of evolution.1,2,3 And yet, evolutionists remain unfazed. So then, what sort of fossil evidence would it take to falsify evolution? Some evolutionists have attempted to give a reasonable answer. Renowned 20th-century evolutionist J.B.S. Haldane, in response to being asked if there was any evidence that would convince him evolution was false, is reported to have said “a rabbit in the Precambrian” (figure 1).

Dawkins, following Haldane, avers:

“However, if there was a single hippo or rabbit in the Precambrian, that would completely blow evolution out of the water. None have ever been found.”4

But would a ‘Wascally Wabbit’ fossil assemblage in the Neoproterozoic really disprove evolutionary paleontology to an evolutionist?

Explaining it away

Clearly, a Precambrian rabbit would go against the prevailing understanding of the fossil record, so it would engender a lot of skepticism. Depending on the quality of the reporting, questions such as “Has the fossil been identified correctly?” and “Is the find a hoax?” might be part of the escalating chorus of public enquiry. But the question most likely to take prominence in the skeptic’s arsenal is “Are the fossils really that old?”

One of the most (in)famous examples is the rather convoluted story of the hominid fossil KNM-ER 1470.5 After the discovery of KNM-ER 1470, the tuff deposit associated with the fossil was first ‘dated’ by the K-Ar method at 212–230 million years (Ma), but since hominid fossils are ‘clearly’ not that old, the ‘date’ was rejected.

Analysis of selected samples gave an ‘age’ of 2.9 Ma, which was considered acceptable. This was ‘corroborated’ with numerous other methods, and was widely accepted. That is, until another palaeontologist, Basil Cooke, said those dates were 800,000 years too old based on pig fossils. The pig fossils won the argument—over the five different dating techniques that were all consistent with each other in giving a ‘date’ around 2.7–3.0 Ma. Therefore, the presence of certain types of fossils and evolutionary assumptions provide the primary dating information, and are often used to override other dating methods, even when those other dating methods are all consistent with each other!

A real Precambrian rabbit scenario

Perhaps the biggest mistake that evolutionists make on this topic is thinking that it is merely a theoretical problem. However, something equivalent has been documented in the secular literature—pollen found in Precambrian metamorphic rock from the Roraima formation in South America ‘dated’ at 1.7 Ga old.6 In the orthodox evolutionary timeline, pollen is supposed to be over 1 Ga younger than these rocks supposedly are. Numerous attempts to explain away the presence of pollen have been made, but they have all been answered. Contamination from the environment has been cited (not really a problem for rabbit fossils, though seemingly a valid consideration for pollen fossils), but this simply doesn’t fit with the geology of the Roraima formation or its surroundings.

Another has been skepticism at the identification of pollen—after all, it is in metamorphic rock. However, recent experiments have shown that pollen fossils can survive the high temperatures and pressures required to form metamorphic rock.7 The Roraima group is unlikely to be redated to anything amenable to evolution, and the idea of a hoax is patently absurd. This has left secular researchers bewildered for over 50 years.

How do they deal with this conundrum? They adopt a ‘wait and see’ approach, with implicit faith in naturalism. They proclaim that it is an ‘unsolved mystery’ in the hopes that future evidence will give an explanation. The evolutionary scheme is not at fault (of course!); we just don’t have enough information yet.

So evolutionists are quite comfortable with these sorts of conundrums because they have implicit faith that naturalism will explain everything. And yet, after nearly 50 years, we’re still waiting for a solution.

Pulling a ghost rabbit out of the hat

Nevertheless, Dawkins’ statement only demonstrates his lack of imagination in coming up with an evolutionary scenario to explain it; not that it couldn’t be done. There is a rationalization commonly used by evolutionists that can accommodate practically any fossil pattern into the evolutionary story—ghost lineages:8

Any cladogram can be placed in a temporal framework that agrees with the stratigraphic record if sufficient ghost lineages are invoked [emphasis added].”9

Ghost lineages are fossil lineages extended millions of years before the oldest find of a particular fossil. This occurs when fossils pronounced ‘ancestral’ based on morphology are thought to be much older than the evolutionary fossil dating indicates.

It’s quite likely that evolutionists would simply project the evolutionary process back into the Precambrian, and then invoke the Precambrian rabbit as evidence for the existence of the phylogeny yet to be more fully documented in the Precambrian.

Combine ghost lineages with the promise of future discovery (especially if most of the surviving Precambrian rocks are hidden from view), and you have ‘evidence for evolution’.

This may seem unlikely, since we are talking about not just one ghost lineage, but a whole ghost cladogram being projected back at least 600 Ma. However, it has happened before. Evolutionists don’t hesitate to invent a whole ghost cladogram of unobserved species out of thin air when they think it is necessary. For instance, basal ornithopod Thescelosaurus neglectus, dated to about 66 Ma, requires a ghost lineage of nearly 100 Ma, which is deemed too long for it to remain static:

“Short of extending the stratigraphic range of T. neglectus across this stretch of time, it is more likely that the gap represents a ghost lineage partitioned by successive, but yet undiscovered species. Given the species longevity values calculated by Dodson (1990) it is clear that there must be considerable species diversity masked by the ghost lineage leading to T. neglectus, perhaps much more than the known diversity of the entire hypsilophodontid clade as presently recognized [emphasis added]!”10

Moreover, evolutionists have had no problem pushing some major evolutionary transitions back 1.5 Ga on the basis of fossils.11 For such a scenario to work, the whole evolutionary tree required to evolve a multicelled organism has to be postulated out of thin air along with fossils.

Behind the ghostly illusion

Voilà! We can pull a Precambrian rabbit out of the fossil hat without hurting evolution. Of course, evolutionary history would have to be drastically rewritten if a Precambrian rabbit was ever found, and neo-Darwinism, as a particular hypothesis of how evolution works, might have to be thrown out completely. However, evolution in the broadest sense—naturalism applied to biological origins and history—could still offer an explanation for it, however counter-intuitive and lacking in experimental verification the explanation may be.

Interestingly, evolutionist philosopher of science Peter Godfrey-Smith agrees:

“This finding [a fossil rabbit in the Precambrian] would not be the instant falsification of all of evolutionary theory, because evolutionary theory is now a diverse package of ideas, including abstract theoretical models as well as claims about the actual history of life on earth. … But a Precambrian rabbit fossil would show that somewhere in the package of central claims found in evolutionary biology textbooks, there are some very serious errors. These would at least include errors about the overall history of life, about the kinds of processes through which a rabbit-like organism could evolve, and about the ‘family tree’ of species on earth … . The reassessment could, in principle, result in the discarding of very basic evolutionary beliefs—like the idea that humans evolved from nonhumans.”12

Paleontology seeks to describe the location and history of fossils observed in the rocks. The spatial relationship between the fossils can be described directly as far as we can observe them—it is observational science. However, describing the distribution of fossils in time is completely different—it is natural history. Natural history is unrepeatable and unobservable. Reconstructing said history involves more than just what we directly observe in the rocks. Natural history is also bound up with the starting assumptions (or axioms) one brings to the investigation. One’s axioms determine what types of evidence are relevant and what could have happened in the past.13 Within paleontology, molecules-to-man evolution is an axiom. However, it is a faulty axiom and so is prone to producing just-so stories.14,15 And as our Precambrian rabbits example shows, evolution can provide a just-so story for any pattern in the fossils. The ‘ghost lineage’ and the ‘wait and see’ approaches have something fundamental in common—an unwavering faith in ‘all-powerful’ nature, even when it borders on the absurd.
