For evolutionist...

I've asked this question a few times to evolutionist and usually get an "I don't know" kind of answer but I'll try again. Is there any evidence or proof or even the suggestion of proof that at what point in evolution did the ability that bats, dolphins, etc to use sonar or echo location to find food start?

Do a google search. I just did one for 'evolution of echolocation' and you get a number of papers that discuss possible scenarios and current evidence.
