Why would “fossil rabbits in the Precambrian era” destroy the theory of evolution?
J. B. S. Haldane (1892–1964) said that the discovery of a fossil rabbit in Precambrian rocks would be enough to destroy his belief in evolution. Philosopher Peter Godfrey-Smith doubted that a single set of anachronistic fossils, however, even rabbits in the Precambrian, would disprove the theory of evolution outright. The first question raised by the assertion of such a discovery would be whether the alleged “Precambrian rabbits” really were fossilized rabbits. Alternative interpretations might include incorrect identification of the “fossils”, incorrect dating of the rocks, and a hoax such as the Piltdown Man was shown to be. Even if the “Precambrian rabbits” turned out to be genuine, they would not instantly refute the theory of evolution, because that theory is a large package of ideas, including: that life on Earth has evolved over billions of years; that this evolution is driven by certain mechanisms; and that these mechanisms have produced a specific “family tree” that defines th
