The dominant pattern in the fossil record is explosions of new biological forms. The Cambrian explosion is a prime example.
In short, the sequences performed no new function, so no new information was created.
Paleontologist Günter Bechly was a proponent of Darwinism until he discovered significant scientific reasons to doubt the evolutionary story.
Whenever you find papers and articles dealing with the Cambrian fossil record in the usual science journals, there are commonalities.
Evolutionists are still failing to explain the Cambrian explosion. They struggle to explain new complexities or else try to change the subject.
