    An ant can lift a 100 x its own bodyweight.

    Humans can lift 100000x more weight than an ant.

    Yes..but our senses cannot do that, we need gadgets to compensate. The only remarkable thing about humans is our brains. Physically we are inferior to most all other animals in one way or another.
    You say humans have better eysight than dogs which may be true, but an eagle outperforms human eyesight by several factors;
    Now you can say that we have satellites which can spot a golf ball from miles above, but that is not a natural ability, it's another gadget.

    The reason I pursue this is that animals other than humans can have remarkable naturally evolved abilities and deserve our admiration and respect.

    You are spouting in psuedothings.
    There are many superior things of humans. For instance we have a longer lifespan than many mammals.
    And our limb system is superior. We have arms and fingers which allow us to throw stuff and wield swords.

    They deserve not to be slaughtered or put in zoos. Thats about all the respect I give 'em. I am mostly vegetarian so I respect animals more than most.

    And an elephant can lift some 660 lbs with his trunk alone.

    I was addressing the brain function. The brain is unable to distuingish objective truth. It has no direct observation of anything outside of the sensory receptors and it receives its information not from direct obseravtion but from electro/chemical bits from which it must construct a composite pattern.

    Of course an artificial "observer" like a camera is an objective observer. The image passes through the lens directly on the photographic plate, which in humans is the back of the eye and consists of arrays of ganglian cells each sensitive to seperate wave lengths. After seperating the image all this encoded information is fed into brain via the optic nerve, which now has to reassemble these millions of bits and then compare it to its memory of what it is actually assembling.

    While it can distinguish between relative values and can mathematically process these values, the brain never does exactly "know" what it is processing. This gives an advantage in some ways because it is not a rigidly fixed process but sensitive to new information which allows it to modify its "recognition from memory" into a new paradigm.
