Russian scientists announced the discovery of the world’s oldest fossil worm burrows in Ediacaran rocks, even though very few fossils are typically found below Cambrian rock layers. Do these worm burrows help answer the longstanding challenge to evolution called the Cambrian Explosion of life? Evolutionary researchers used warped reasoning in their explanations about how burrowing worms may have impacted ancient life.
The Cambrian includes fossils of all living phyla, plus many extinct phyla. On the basis of evolution, one would expect a gradual and iterative appearance of life forms in the fossil record.1 The abrupt appearance in the Cambrian rock system of so many well-designed life forms challenges the claims of evolutionists.
The worm burrow fossils from Yakutia, Russia, clearly show that animals of that time were fully equipped for burrowing. The team of Russian paleontologists wrote about them in Geology, describing them as organisms that “actively burrowed by peristalsis.”2 Peristalsis is a coordinated wavelike contraction of both longitudinal and transverse muscles. The esophagus uses it when swallowing, caterpillars use it when crawling, and worms living on the seafloor use it when burrowing.
So, do the worms help explain how all those living phyla evolved in only a few million supposed years between the Ediacaran and Cambrian?
The authors suggested that worm churning of sediment affected the local environment, which became “the triggering mechanism” for rapid evolution of Cambrian creatures.2 Dima Grazhdankin, coauthor of the Geology study and paleontologist at the A.A. Trofimuk Institute of Petroleum Geology and Geophysics in Novosibirsk, told ScienceNews, “We think that Ediacaran organisms diversified as a reaction to habitat remodeling by…burrowing.”3….
