Did Echolocation Evolve?

Using my unregistered assault keyboard,
I thought I'd feature an article by Dr. Sarfati on his birthday.

You know how bats send out sound waves so they can navigate? It is like the sonar that is used in submarines using transmitted and reflected sound waves. Biosonar be found in species of "toothed whales" (dolphins, porpoises, some whales). A form of this is also found in some swiflets and shrews.

This is a puzzler for evolutionists. The "explanation" usually comes down to a fundamentally flawed assumption of evolution in one form or another followed by cumbersome "just so stories". (Fossils do not help, so-called "early" bats show the system already in place.) Instead of claiming "convergent evolution" without mechanism or evidence, the best explanation is the simplest one: Work of the Creator.
Sonar was originally an acronym for SOund Navigation And Ranging. As the name suggests, it is a detection method using echoes of sound to detect objects and measure their distances and speeds. However, scientists were taken by surprise when they found that bats and dolphins use exactly the same process. Just like man-made systems, they have ingenious ways to avoid being deafened by their own echoes. Indeed, the living sonar systems are much better than man-made ones. Using the principle of analogy, much used by Darwin himself, one would think that the living sonar systems also had an ingenious engineer behind them.
