Re: Any other explanations other than Mutation?

... the fossil record is inconsistent with current evolutionary theory is worse than inaccurate; fossil lineages display exactly the sort of gradual progression that would be expected from an evolutionary process. If evolution had happened, the fossil record should be showing the unselected species ...
