The biologist J. B. S. Haldane supposedly said that the discovery of a fossil rabbit in Cambrian or Precambrian—accounts differ—strata would definitively falsify evolution.

I will name him George, and I will hug him and pet him and squeeze him.” If you’re the first to provide the correct genus name in the comments section below, I will tell you more about the rabbits.
