    Well, even today there are diurnal bats who do not use echolocation.

    This implies (at least to me) that little is known about how/when bats developed flight - a shame, because it is one of only (I think) 4 times in the history of the earth that it happened.

    Don't we know how that happened?

    Aren't there squirrels that glide? Wouldn't it have happened the same way?

    Okay, maybe little was known to me. But it seemed like they didn't actually know when, if they weren't sure when it was in relation to echolocation.

    Ahh.. Well, I'm not sure either, but it seems to make sense to me. Bats are mammals, just like squirrels.. and those gliding squirrels look a bit like bats, at least to me.

    It is? What are the four?
    If I think about it I have:
    - mammals (bats)
    - dinosaurs (birds)
    - whatever order the flying reptiles such as pteranodon belonged to (pterodactyles?)
    - insects. are all flying insects descending from one single common ancestor? Some have two wings and other 4, doesn't that mean we have at least two different ways that flying evolved in insects?

    Alright, now that you mention it I am not sure about insects, it would make sense to me that all flying insects have a common flying ancestor, but I don't know. I think I read that they did. And yes for the others (pterosaurs being the name of flying non-avian reptiles in general).

    Come to think of it, that would make a great quizz question :)

    And maybe, given enough time, we will have truly flying fishes.

    Are bats from the same line as rodents? I always thought they came from a different line.

    I have no idea.. This is a gliding squirrel though:



    Would make sense that this is how bats evolved the ability to fly, no? They used to live on trees, evolved the ability to glide, and it eventually turned into flight.

    At least that's my guess :)
