    Default Is a nervous system required for intelligence? consciousness?

    It seems that some single celled slime can actually learn.

    The plasmodium of the slime mould Physarum polycephalumis a large amoeba-like cell consisting of a dendritic network of tube-like structures (pseudopodia). It changes its shape as it crawls over a plain agar gel and, if food is placed at two different points, it will put out pseudopodia that connect the two food sources. Here we show that this simple organism has the ability to find the minimum-length solution between two points in a labyrinth.

    Maybe a brain isnt needed for learning.

    Agreed, otherwise the earliest forms of life on Earth would have had a serious problem. In fact, the cells we have in our own bodies learn chemically and through proteins.
    Consider how DNA presents the same appearance of "learning" by its very chemical structure adapting over generations.
