The explanation lies, as I believe, in the extreme imperfection of the geological record. Charles Darwin (1859), The Origin of Species, p. 280. Darwin's statement acknowledges an incomplete fossil record rather than a problem with his theory.The fossil record is as much a document of clade failure as success, and provides a direct observational window on a wide range of natural experiments, in deep time and directly preceding the present biological moment. At the same time, another key finding from the fossil record is a lack of extinction where it might be expected.Nov 20, 2023 · For Christians, the fossil record is a remarkable gift that prompts reflection on the kind of world God has made.
