Studies done on the European continent soon demonstrated the universal validity of index fossils.
That is, an index fossil corresponded to a very specific point in the geologic column.
Note that evolution has nothing to do with how the index fossils are used to date strata!(See Topic A1 for claims of bad dates.) Creationists, on the other hand, must explain to us how sediment and rock laid down in a mere year can yield such fantastic, orderly differences in radiometric ages.This poses a fatal problem whether one believes in the accuracy of radiometric dating or not!One can hardly accuse these pioneers of evolutionary prejudice.Nearly a half-century would pass before Darwin's book, The Origin of Species, was published!
