schreef in zijn boek: Critical Transitions in Nature and Society (p.169-170):
The collapse of the Ediacaran fauna is followed by the spectacular radiation of novel life-forms known as the Cambrian explosion. All of the main body plans that we know now evolved in as little as about 10 million years. It might have been thought that this apparent explosion of diversity might be an artifact. For instance, it could be that earlier rocks were not as good for preserving fossils. However, very well preserved fossils do exist from earlier periods, and it is now generally accepted that the Cambrian explosion was real.
Nelson Cabej (2019), titled Epigenetic Mechanisms of the Cambrian Explosion and published by Academic Press. He said it even more clearly:
Nevertheless, now, 150 years after The Origin, when an incomparably larger stock of animal fossils has been collected, Darwin’s gap remains, the abrupt appearance of Cambrian fossils is a reality
, and we are still wondering about the forces and mechanisms that drove it. Despite the fact that, from time to time, a small number of students have questioned the reality of the Cambrian explosion on the same ground as Darwin, today’s consensus is that Cambrian explosion is a scientific fact
(Linnemann et al., 2019) … The Cambrian explosion is real
and its consequences set in motion a sea-change in evolutionary history (Conway Morris, 2000; Nichols et al., 2006). … Despite the accumulation of an immense fossil record, the development of a relevant theoretical groundwork, and the numerous attempts to deal with the causal basis of the Cambrian explosion, just like in Darwin’s time, it continues to be one of the greatest enigmas of modern biology
. …Many hypotheses have been presented on the causal basis of the Cambrian explosion. Today, we are still grappling with the question, but no closer to understanding the nature and causes of the Cambrian explosion. … The erection of the metazoan structure, as an improbable structure, requires an immense volume of information
, compared to which the information contained in even the most complex genomes represents but a negligible fraction.
But it is not just the “abominable mystery” and the Cambrian Explosion, because the same holds for the origin of life, the origin of photosynthesis, the origin of the Ediacaran biota in the Avalon Explosion, the Great Ordovician Biodiversification Event, the Siluro-Devonian Terrestrial Revolution of land plants and land animals, the Devonian Nekton Revolution and Odontode Explosion, the Carboniferous Explosion of winged insects, the Triassic explosions of tetrapods, marine reptiles, flying reptiles, and dinosaurs, the Cretaceous Terrestrial Revolution, the Paleogene origin of butterflies, the Big Bang of modern birds and placental mammals in the Paleogene (Lower Tertiary), and even the Big Bang of the genus Homo and its Upper Paleolithic Human Revolution of symbolic culture (Bechly & Meyer 2017). There is a reason why mainstream paleontologists and evolutionary biologists called these events Big Bangs, explosions, and revolutions. Nobody would call a slow gradual change or a mere methodological artifact a revolution or an explosion. There is clearly a pattern of discontinuities that requires an adequate explanation, and Darwinism is not it.
