Recently I have heard the phrase 'Rabbit Fossils In The Precambrian' many times. What does it mean and how does it relate to creationism/evolution?
The idea here is that the Precambrian is way longer ago than mammals are believed to have existed. So a famous scientist once said that if they found rabbits in the Precambrian he'd say the theory of evolution is not true.
There have not been any such fossils found.
Much of the talk about this centers around whether evolution is "falsifiable." In other words, could you ever find proof that the theory of evolution is wrong.
