There is basically no data that supports the crazy theory that small mutations and natural selection create the enormous macro-evolution that darwinists think they're explaining, the fossil registry is very clear. The main theory is full of holes, paradoxes, unexplained oddities, ad-hoc fixes that defy reason, and it still falls much short of achieving what it intends to. Even Lamarckism has to be invoked these days to save Darwinism.
