Evolutionary Faith and the Cambrian Explosion
Way back when Charles Robert Darwin was popularizing his version of evolution, he admitted that a problem with his "tree of life" idea was the scarcity of transitional forms. He had faith that maybe someday these would be found. Then there was the insurmountable problem of the Cambrian explosion...
By blind faith, evolutionists claim to have many transitional forms. These are disputed, and even the word transitional has been the subject of obfuscation. In Darwin's time, the Cambrian was known as the Silurian age. Instead of the orderly progression of fossils indicating simpler to more complex life forms, the Cambrian layer had complex life forms exploding on the scene without any signs of transitional forms.
The fossil record is contrary to the evolutionary tree of life, and evolution's defenders have contrived many rescuing devices. For example, if creatures were considered extinct but later found doing right well, or have remained unchanged over the vast amount of imagined evolutionary time, they are called living fossils. Suddenly, the irresistible "evolutionary pressures" did not apply, so the critters were in "stasis". Also, when fossils were found in lower layers and then reappeared in higher levels, Darwinoids invoke "ghost lineages" or "Lazarus taxons" for those.
When all else fails, the old "Stuff Happens Law" kicks in. Personally, I prefer the complex scientific principle of Making Things Up™. Isn't evolution wonderful? It can explain everything — so it actually explains nothing.
If you study on it a spell, you should see that evolution is based on blind faith. Dig deeper into the fossil layers, and it should become apparent to rational people that the evidence supports recent creation and the Genesis Flood, not deep time and gradual processes.
Evolutionists claim the Cambrian rock layers were first laid down about 540 million years ago. Highly complex multicellular creatures known as metazoans and a plethora of hard-shelled creatures suddenly appear in these sedimentary strata. Examples include clams, snails, horseshoe crabs, trilobites, sponges, brachiopods, worms, jellyfish, sea urchins, sea cucumbers, starfish, brittle stars, sea lilies, and other complex invertebrates.
Making this mystery even more evolution-defying is the fact that the rock layers below the Cambrian are devoid of invertebrates. While this was known in Darwin’s day, the mystery has never been resolved, and a 2018 study reported that a thorough re-analysis of the Precambrian Ediacaran sediments showed they are completely empty of evolutionary ancestors.
