While bats live in air and dolphins live in water, both use a biological form of sonar technology called echolocation to see with sound! The specifications in dolphin and bat biosonar systems are so many, so well-integrated, and so precise, could they really have developed at random in two completely different environments?

Who has ever heard of a fossilized brain? Few would expect such a discovery, yet it looks like that's what researchers found inside a Stone Age skull from Norway. If so, it would confirm a published creation prediction and challenge many evolutionary timescales.
