Bat Echolocation and the Master Engineer

Purveyors of molecules-to-mammals evolution tend to get on the prod when creationists and the Intelligent Design folks point out things that clearly indicate intelligent design. (One example is cellular machinery.) Their dogma is that things only appear designed.

To be blunt, that is galactically stupid. We frequently find examples of the Master Engineer's brilliance and of specified complexity, and to keep saying they only appear designed is cultlike. Or maybe mental illness. A new example is echolocation and the speed of sound.

Bats have always been recalcitrant toward the desires of evolutionists, as the fossil record shows that they have remained bats through millions of Darwin years. Now it has been demonstrated that bats are hardwired for echolocation, and they do not adapt well to changes in environments. That reveals design, not evolution and environment.

Bats have the amazing ability to accurately and consistently detect the speed of sound. This enables them to employ a complex system of echolocation in the dark of night to find food in mid-flight and to avoid slamming into trees. But unlike processes in many animals that use a system of learning such as birds singing or lions hunting, bats seem to be hard-wired in their ability to echolocate from birth.

As Bats fly around at night, they emit high-pitched signals that reflect off distant objects. The echoes from these are then translated by the bat’s echolocation system based on the time it takes the echo to return, giving an accurate measure of distance. Depending on air conditions (e.g. temperature, humidity), sound waves can move faster or slower and the bat is able to adjust and accommodate for this within a specified range.
