Fish with Limbs

Posted by michael on from the stop-poking-me dept.

  1. Reminds me of wings by PIPBoy3000 · · Score: 5, Interesting

    One of the typical arguments by creationists is how can evolution make these jumps from legs to fully functional wings. The latest thinking is that there's wasn't a giant leap, but rather a series of gradual steps between limbs that didn't impart flying, but still had some use.

    For example, chickens don't fly very well, but have you ever tried to catch a chicken? Those "vestigial" wings sure impart bursts of speed and the ability to leap over obstacles.

    It's neat to see the discovery of similar intermediaries between swimming and walking limbs. Evolution is an amazing and beautiful thing.

    "...multiple seperate occasions..."

    Not just that, but _differently_ in each of the major eye types. There's no "animal eye", there are at least 3. (I forget exactly how they're categorised, but they're roughly vertibrate, cephalopod, and creepy-crawly.)

    In particular, our retinas are 'back to front'. It's an flawed design, and that's why we have blind spots -- it's where the nerves leave the inside of the eyeball. If our eyes came about through _design_ then it was _crap_ design.

    God-freaks can take the soft cheese out of their ears now.
