Bats have the extraordinary ability to close their ears as they send sonar signals and reopen them in time to hear returning echos. They do this at the incredible rate of 50 to 60 times per second. Studying the bat's unique method of detecting objects has allowed scientists to discover the principles of sonar. Using these principles, mankind has produced sensitive detection intruments of his own.
As complex and sensitive as our sonar detection systems are, they still lack the precision of the bat's. It is estimated that the bat's sonar system is still many times more sensitive than anything man has yet designed. We know it took man's intelligence to design his detection systems. Isn't it foolish to assume a bat's sonar system, which is much more complex and sensitive, happened by accidental mutational changes?
