A Precambrian rabbit is a hypothetical fossil that anti-creationist-leaning scientists have given as an example of what could change their minds. It was originally stated by J.B.S. Haldane (1892–1964) but in certain circles, especially philosophy of science, has taken on a life of its own: a frenzy of speculation and other very typical academic activities. [1] [2]

This precambrian rabbit is, essentially, a metaphor for this puzzle: since there is an order in the fossil record, with primitive life forms occupying deeper (and, radiometrically, older) layers, how do Creationists explain that there are no modern lifeforms (like rabbits) in older sediments (like those from Cambrian or earlier)?[3]
