How Seahorses Evolved To Swim Standing Up

Posted by Alex in Animal, Science & Tech on May 24, 2009 at 12:55 pm


Peter Teske and Luciano Beheregaray of Macquarie University in Sydney, Australia, have just solved one of nature’s most enduring mysteries: how seahorses evolved to swim standing up …

Seagrasses, which thrive in shallow water, spread rapidly through these newly formed environments. The researchers think that the ancestors of modern seahorses followed.

Horizontally swimming fish living in seagrass beds don’t blend into the environment well and are easily picked off by predators.

A solution seems to have evolved in seahorse ancestors: the upright body shape, which enables seahorses to seamlessly blend in with surrounding seagrass.

    I have always been dumbfounded by how researchers profess to know how many things have come to be.

    I mean without OBSERVING something first hand you can't really KNOW how something developped.

    Sure you can throw all matter of complexity, theory, hypothesis, etc. at something and say it's true when you are all done lookingat the data as you see it, but you'd just be kidding yourself if you said you knew it came to be this way or that because of whatever factors you decided to look at...

    But to their credit at least they throw in words like think, may, could, etc. That way in ten years when their idea look like total crap they can never take less responsibility for their crap ideas.

    Pretty much the same way that man evolved to pee standing up.

    No, VonSkippy, man pees standing up because it's so much fun.

    Timm, get a life. The hypotheses of scientific thought are vastly preferable to blindly accepting the word of a cult leader with preposterous ideas and no basis in fact. For example, Jim Jones and L Ron Hubbard.

    Now granted, I didn't read the paper that I'm sure they published on this but your header says they've "proved" how seahorses evolved to swim standing up. So where's the proof? Saying "grass is upright, and so are the seahorses, therefore that's WHY they're upright" doesn't sound very scientific to me... What about all those creatures that live inthe long grass that haven't evolved to swim upright. How come they survived?
