PhysOrg: Bird beaks did not adapt to food types as previously thought, study suggests

If this sort of thing keeps up, Darwin’s original theory will become one of those known wrongs that remains right because the principle is too important to abandon.

  1. One should not, of course, read too much into stories like this.

    Here the main significance is that Darwin deduced a mechanism from what is now shown to be an insufficient data set. This occurs in the normal process of science, and it doesn’t mean the mechanism is false. On the contrary, it may tell us something useful about intuition and consciousness.

    I’m encouraged to continue holding out for the hypothesis that intelligence is an attribute of the natural world, separately and apart from the human being.

  2. “The connection between beak shapes and feeding ecology in birds was much weaker and more complex than we expected and that while there is definitely a relationship there, many species with similarly shaped beaks forage in entirely different ways and on entirely different kinds of food.
    “This is something that has been shown in other animal groups, but in birds this relationship was always assumed to be stronger.”
    Co-author, Dr. Jesús Marugán-Lobón from Universidad Autónoma de Madrid, said: “These results only made sense when you realise birds use the beak for literally everything!”

    I think Darwin is still on solid ground. The mechanism of evolution is what evolves in science.

    1. RE: “I think Darwin is still on solid ground.”

      He’s on less solid ground than previously. Where once we assumed his logic was sound, now we cannot. The scientific case for natural selection as the origin of species is growing weaker, even if we can still show that natural selection is real.
