How does a tree (or any plant, really), know to evolve to produce a delicious fruit or a poison berry, a seed inside an impenetrable shell, or invent a type of flying machine, in order to reproduce? (Each of these examples exists in my backyard)

How do they receive feedback about their evolutionary experiments? How do they know it worked/failed. [10]

    Random mutation. If it reproduces successfully, those genes pass on. If successful enough, it could become the dominant variety. If not successful, that variety will be a small population or die out. That’s all there is to it.

    I’m with you. My wife has REALLY gotten into plants in the last year or so, and it amazes me how “smart” they are.

    Obviously, everyone here is right. There is no intelligence, just genetics, but watching my morning glory wall climb the rope net to the roof of the house just blows my mind.

    It’s crazy to think about all the trial and error over the centuries that it took for a simple flower to develop little sensor hairs that explore its surroundings and wrap itself around anything in range.

    There is no knowing or feedback.

    Mutations are random and there are many more failed mutations than successful ones.

    You only see the successful species for that very reason, the failed ones have not been able to compete or pass their genes on at an appropriate rate.

      Well, that’s feedback.

      That the feedback mechanism that makes the process work. What is hard to understand is that it “informs” a population, not any individual.

        It’s feed back only in the sense that it can be seen as a success or a failure by an independent observer.

        It’s not like a tree can see that last year’s seeds weren’t very good and try a different mutation this year.

        Genes are not self aware, mutations do not have an end goal and survival simply comes down to chance.

    They don’t know. They exist because their traits allowed them to survive better than other traits. If an evolution fails, they cease to exist. What’s left over is what you get to see
