Let’s address this issue by first defining our terms. Although many definitions have appeared, science can be described as what we really know to be true mainly through observation. The late G. G. Simpson of Harvard stated in Science magazine that “it is inherent in any definition of science that statements that cannot be checked by observation are not really about anything . . . or at the very least, they are not science.”
But the origins debate centers around macroevolution, and macroevolution has never been observed. One of the architects of neo-Darwinism agrees: “It is manifestly impossible to reproduce in the laboratory the evolution of man from the australopithecine, or of the modern horse from an Eohippus, or of a land vertebrate from a fishlike ancestor. These evolutionary happenings are unique, unrepeatable, and irreversible” (Theodosius Dobzhansky, American Scientist, December 1957).
