 Hence, "Precambrian rabbits" would prove that there were one or more serious errors somewhere in this package, and the next task would be to identify those errors.Benton pointed out that, in the short term, scientists often have to accept the existence of competing hypotheses, each of which explains large parts—but not all—of the observed relevant data.Genuine fossils of earliest rabbits are from the Eocene Epoch, about 56 to 33.9 million years ago.
