The sweeping claims made by many evolutionists stand in stark contrast with their specific admissions. They claim, in general terms, that evolution is well established. But when the question is that of the origin of some particular creature, doubts and vague speculation abound. Moreover, while they claim that there is abundant evidence for evolution, when pressed for details they have to admit that the fossils show gaps, not continuous variation. As for the other alleged evidence, it is evidence only to someone already determined to believe in evolution.
