Hummingbirds actually proves my point here, on how life and death solve the symbol grounding problem. What is a "stable grasp"? An entire body of classical robotics literature is devoted to answering this problem. I work on robotic grasping research and defining what it means to grasp something successfully is a little tricky unless you have a broader context of what the grasping is for. Nature doesn't care whether hands exist or not - only that the animal can feed. That is why we see such a spectrum of appendages in the animal kingdom. Some are hand-like, others not at all, and some in between. In some sense, "hand" is a mental construct of human language.
