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?
In the 19th century, the theory of abiogenesis was widely accepted, much like evolution is today. Charles Darwin strongly promoted the idea that life was generated spontaneously from non-life. However, Louis Pasteur, a French microbiologist and believer in biblical creation, made a startling discovery that turned this notion completely upside down.
