I think I should explain a little about what is is and for what stands for...
The idea of Precambrian rabbit emerges as a responce created by the biologist J.B.S. Haldane, being the answer on which evidence could make it destroy his confidence in the theory of evolution. Assumes that the discovery of a lagomorph mammal in Precambrian strata, long before the emergence of the first chordate, it could overthrow the theory of evolution instantaneously. But even if it is authenticated such discovery, it would show that there are serious errors in the modern understanding of evolution and evolutionary animal history, and probably would not refute the theory abruptly since this one contains a huge set of ideas and mechanisms, that would probably have to be re-evaluated to identify such errors that can explain such anomaly.
Evolution is not a belief that runs on evidence. Its a system that reshapes evidence to its beliefs.
Good drawing, though XD
