New fossil finds further verify one of evolution's biggest problems: the Cambrian explosion. According to evolutionary reckoning, a massive explosion of new life supposedly spawned dozens of brand-new fully formed body plans about 530 million years ago. How could so many novel body plans emerge in such a short time while today's emergence rate of new body plans is zero? Details from newly discovered Canadian fossil fish intensify this Cambrian conundrum.
Very few fossils show up in rock layers below the Cambrian—some sponges, cnidarians, a mollusk, what look like worm trails, and several fossils now reclassified as non-animals, known as the Ediacaran fauna. Then, suddenly, most of the basic animal forms occur in Cambrian rocks, including echinoderms (e.g., starfish), various arthropods including shrimp and sea scorpions, clams, brachiopods, annelid worms, and chordates—a group of animals including vertebrates like fish.
This fossil pattern falls afoul of evolutionary expectations. Simpler animals in lower rocks, from supposedly earlier times, evolved into more complicated animals like chordates and those should appear in upper rock layers according to evolution. Instead, most fundamental animal forms classified as phyla, occur in lower Cambrian strata. In other words, instead of a slow and gradual appearance of new life forms, the fossils show just the opposite: the sudden appearance of fully-formed creatures.
...So, fully formed fish occur in both Chinese and Canadian Cambrian layers. This means the evolutionary problem of the Cambrian explosion is real and intense.
Reams of new information in the form of biological coding, represented by dozens of novel cell types in Cambrian fossils, demand a reasonable cause. A Precambrian sponge would have had five cell types, but the Cambrian fish had 60 cell types, equivalent to an encyclopedia of brand-new biological information.
Plus, over 67 percent of animal phyla have their lowest occurrence in the Cambrian. That's a lot of new animals suddenly appearing fully formed, and those same body plans have not changed.
If evolution is not adding new suites of biological information to any of today's creatures, then how could it have added so much, so fast, so long ago? Whereas the Canadian Cambrian fish Metaspriggina certainly punctuates this longstanding and unanswered challenge to evolution's defenders, it follows nicely from the biblical concept that Cambrian rocks represent the first of many Flood deposits, burying creatures that God had purposely fashioned.
