I found this quite funny

Fossil find suggests microbats evolved the ability to fly before developing echolocation.

It might be just me – but I had a sudden mental picture of all these bat flying into things… and eventually figuring out they could use the echoes of other bats yelling “Ow!” to find out where things were.

I mean – how useless is the ability to fly without the ability to “see” where you’re going?
