"Ancient bat flew without 'sonar'"
Disappointingly little is said of why it makes a difference whether flight or sonar developed first, but an interesting article nonetheless. Perhaps a good starting point for further personal research into the possible impacts of this find - someone must have a good explanation of why this is important. I hope it's not just because "it's cool" - that would be slightly disappointing.
