Mystery of the Empty Strata
As one digs deep into the earth, one layer or stratum after another is revealed. Often we can see these layers clearly exposed in the side of a mountain or roadbed cut. Geologists have given names to the succession of strata which pile one on top of another. Descending into Grand Canyon for example, one moves downward past the Mississippi, Devonian, Cambrian, etc., as they have been tagged by the scientists.
Now here is the perplexity for the evolutionary theory: The Cambrian is the last stratum of the descending levels that has any fossils in it. All the lower strata below the Cambrian have absolutely no fossil record of life other than some single-celled types such as bacteria and algae. Why not? The Cambrian layer is full of all the major kinds of animals found today except the vertebrates. In other words, there is nothing primitive about the structure of these most ancient fossils known to man. Essentially, they compare with the complexity of current living creatures. But the big question is: Where are their ancestors? Where are all the evolving creatures that should have led up to these highly developed fossils? According to the theory of evolution, the Precambrian strata should be filled with more primitive forms of these Cambrian fossils in the process of evolving upward.
Dr. Daniel Axelrod of the University of California calls it: "One of the major unsolved problems of geology and evolution."
George Gaylord Simpson, the "Crown Prince of Evolution", summarized it: "The sudden appearance of life is not only the most puzzling feature of the whole fossil record but also its greatest apparent inadequacy." The Evolution of Life.
