The monkey s math predisposition

The factor of free hands and 10 advanced fingers

Why monkey eventually and at first found the way which lead to awakening consciousness? Why this ugly but impish creature had granted by nature with such superiority in front of so many much more advanced, strong, smart and extremely skilled animals, birds, fishes?
Naturalists pointed to the hand of monkey, his palm and fingers as some device, which played crucial role into that great discovery. As said Marx the work transformed monkey into human and our hand, palm and fingers are the device and result of this magical transformation.
And what’s more it kept evidence and answer to our question - why is that happened with us? Why that didn't get with elephant and his trunk - another very sensitive device, with the octopus and his tentacles, with the snake and it's tail and other evolutional competitors of primates?
I am seeing the answer in the 10 fingers of our hands, which have a great rate of freedom compare with hand, elbow, shoulder also very freely elongated upon our body when we walk, work and so on. I thought those fingers had triggered at first mathematical awoken of ancient human and help him increasing memory and find way to abstraction.
