Bats and Sonar

Dark nights bring out the bats. Actually, they generally start their activity at dusk, and eat a passel of insects among other things. They're also pollinators and effective seed dispersal units (through guano, like birds), and bats are beneficial in many ways. But don't get careless, they're wild animals and should not be handled by untrained people.

No, they're not blind, so you can leave that "blind as a bat" expression behind. But not many critters can see so well in total darkness, so they have other ways to compensate.

Bats are amazing animals, and have an intricately designed echolocation system.

Bats have an amazing echolocation system. There is no evidence for evolution of bats or their abilities, even though evolutionists still insist that EvolutionDidIt™. Also, some of the moths and other insects they eat can sense the sonar and take evasive action. Then the bats compensate. The more bats are studied, the more amazing this complex system really is — and that's a strong testimony to the Creator. Evolution? Not hardly!
Picture a calm summer evening. Most people are only dimly aware of the aerial creatures that may dart and dive nearby. Indeed, many would think these animals are birds unless their activity is closely observed. They would be surprised to discover these flying creatures are actually bats using their designed sonar to detect and track insects as small as mosquitos—prey these bats pick up and devour on the wing and in the dark.

Looking at the amazing design features of a typical bat, Douglas Futuyma assumes “the only scientific explanation of adaptations is the theory of evolution by natural selection.”
