  1. I watched this upside down… How come a bird doesn't descend when doing the "recovery" flap? Meaning the opposite of pushing itself upwards.. Don't it push itself downwards in the other stroke?

  2. When we talk about single trait it is easier to credit evolution
    Now try to put every single trait a single creature has and tey to prove it can happen randomly using maths and statistics. Now pit every single living being in ur formula and watch the number

  3. Very interesting!

    1. The last 20 seconds send like a overly complicated and ridiculous "scientist explanation" of something that's actually simple; they can feel it , so they adjust until it's "comfortable" (how do surfers continually find a wave? They're aiming for it. )

    2. Does this mean that the bird at the beginning of V is always the lowest? I don't recall ever seeing or hearing about that association.

    …. flying must feel so Fn cool! Like treading water, but without the need to remain on the surface (and every time you stop, you accelerate blindingly downward!)
