For the first third of this century most creationists held to the concept that there was no general sequence to the fossils, but that they were arranged into the "geological column" simply to support the theory of vast ages of time. More recent studies suggest that there is a general sequence, although not in such detail as the evolutionists hold. In order to explain this orderly arrangement, the ecological zonation theory has been proposed, and has been accepted by many creationists. According to this theory the fossil "zones" are the remnants of the original life zones of the antediluvian earth. Some questions and problems are discussed, and answers suggested.
