The term “Cambrian explosion” refers to the sudden appearance of a large number of new taxa of animals of higher rank (classes, types) on the geological scale, documented by the excavation of sedimentary strata belonging to the Cambrian period of geological time. For 150 years, this evolutionary phenomenon has remained unsolved from the standpoint of traditional Darwinism, nor from the standpoint of its later modifications – the Synthetic theory of evolution and the theory of discontinuous equilibrium. Up to now, creationism was regarded as the only alternative to solving this problem. The author of this work, analyzing the vast factual material presented by embryologists, zoologists, paleontologists, molecular biologists, including those obtained at the end of the 20th and beginning of the 21st centuries, offers a new natural-scientific concept to explain the causes for the explosion of macroevolutionary variability at the beginning of the Cambrian period.
