Cambrian Explosion Louder Still
Darwin started a tradition of worrying about the Cambrian Explosion. Over time the problem has only worsened; now we know that all the animal phyla appeared suddenly in the oldest strata containing metazoan (multi-celled) animals. In recent decades, evolutionists had hoped that the strange Ediacaran fossils would provide the needed missing links. In addition, some thought they had found embryos of early metazoans in the exceptionally-preserved Precambrian beds of China. Those hopes have now been dashed, leading to moans and groans from Darwinians.
New techniques have allowed a closer look at the alleged embryos. Using a non-invasive synchrotron X-ray microscope, an international team has reported their findings in Science.1 Result: not embryos, but cysts of protists. N. J. Butterfield, writing in the same issue of Science,2 explained the misery of disappointment:
Ever since Darwin there has been a disturbing void, both paleontological and psychological, at the base of the Phanerozoic eon. If his theory of gradualistic evolution be true, then surely the pre-Phanerozoic oceans must have swarmed with living animals—despite their conspicuous absence from the early fossil record. Thus, the 1998 report of fossilized animal embryos in the early Ediacaran Doushantuo Formation of South China was met with almost palpable relief. It was indeed the fossil record that had let us down, not the textbooks, and certainly not the exciting new insights from molecular clocks. All was not as it seemed, however, and new data from Huldtgren et al. on page 1696 of this issue,1 look set to revoke the status of these most celebrated Ediacaran fossils.
The main point is that these spores are not on the way to becoming animal body plans. “Although unquestionably eukaryotic, the fossils are not metazoan, or even properly multicellular by all appearances,” Butterfield said. The researchers tried to put a semi-happy face on their conclusion by claiming it might still represent a transition “that evolved after the last common ancestor of animals and fungi, but before the last common ancestor of living (that is, crown-group) animals”. Here’s what Butterfield had to say about that: “In terms of progressivist storytelling, this all seems a little too good to be true,” since other microbes have a similar growth habit. The authors even acknowledge that “the much broader distribution of this habit undermines its utility as a phylogenetic marker,” Butterfield added.
Yet Butterfield struggled to maintain his equanimity in spite of the disappointment. “Interpretation at this level is inevitably impressionistic, but to my eye there is still a case for identifying the Doushantuo fossils as embryos, albeit algal rather than animal.” Needless to say, an alga is not anything like an animal (think trilobite with articulated limbs and complex eyes; see 12/07/2011).
In the expected manner of P.R. departments, the University of Bristol put out a press release spun in progressivist storytelling, with the tried-and-true “shedding light” metaphor: “Chinese fossils shed light on the evolutionary origin of animals from single-cell ancestors.” PhysOrg inhaled and exhaled it unprocessed, even with the triumphalist but contradictory preface:
All life evolved from a single-celled universal common ancestor, and at various times in Earth history, single-celled organisms threw their lot in with each other to become larger and multicellular, resulting, for instance, in the riotous diversity of animals. However, fossil evidence of these major evolutionary transitions is extremely rare.
To get to the agony of defeat, one needs to move past the cheerleading headline:
Professor Philip Donoghue said: “We were very surprised by our results – we’ve been convinced for so long that these fossils represented the embryos of the earliest animals – much of what has been written about the fossils for the last ten years is flat wrong. Our colleagues are not going to like the result.”
Professor Stefan Bengtson said: “These fossils force us to rethink our ideas of how animals learned to make large bodies out of cells.”
One remarkable facet of these fossils was noted in the press release: “The organisms should not have been fossilized – they were just gooey clusters of cells – but they were buried in sediments rich in phosphate that impregnated the cell walls and turned them to stone.” What this implies that if real metazoans or their embryos were present, they could have been preserved.

“Progressivist storytelling.” Nice. That was Butterfield’s term. You don’t have to quote us to prove that Darwinism relies on progressivist storytelling. They know it. They just don’t always say it. If you removed the hopeful hype from evolutionary papers and press releases, you would be left with data that support intelligent design.
Those who have watched the documentary Darwin’s Dilemma might recall that it referred to the Doushantuo fossils as embryos. Even if that interpretation is now shown to be incorrect, it doesn’t change the argument: strata that were able to fossilize “gooey clusters of cells” should have been able to preserve transitional animals if they were present. The point is actually strengthened by this paper. They weren’t even embryos; they were clumps of microbes! So not only does this increase the phylogenetic distance between Precambrian fossils and Cambrian metazoan fossils, it shows that no transitional forms appear in the ideal conditions of the Chinese Doushantuo deposits. Score another shutout against Darwinian evolution.
Butterfield spoke of a “disturbing void” among evolutionists that was in part “psychological”. Do you have a void in your life? Are you feeling something big is missing from your world view? Would you like to fill that void? Christians teach that we all have a God-shaped vacuum in our soul that only God can fill. That’s what Christmas is about: the Creator of life on earth has communicated with us in the person of God the Son, giving us hope, meaning and purpose. Do some research this holiday season.
