Evolutionists have made much of fossils. They supposedly illustrate the progression of evolution. Yet, there are serious problems with this fossil record.
Dr. Duane Gish has written a book about these problems. One big problem is the missing transitional forms—the "missing links". Evolutionists have claimed that more primitive fossils are found in geologic layers lower than where more advanced life forms are found, and assuming the higher layers were laid down much later than the lower layers, the more primitive forms thus lived earlier, and the more advanced forms evolved from the more primitive.
However, let us not be hasty and jump to such conclusions. One possibility is that more intelligent, advanced life forms would be more likely to attempt to escape rising waters of a flood by moving to higher ground. Thus, they might become fossilized in higher layers than less intelligent, more primitive life forms. Also, concerning fossils and the layers in which they are found, the findings have not always been "in the proper order."
