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.
