The one function we do not want to lose is the thumb, it is what defines the human hand, it is unique to humans so unique in evolution.

Not accurate, mi amigo.

Agree with the rest, though.
The more the hand could do the more we used it, the more the brain and the physical needs to have this were developed, or was it that we developed the physical and so with more movement available the brain had to grow to accomodate these new workings?
The body mechanics of the hand have taken millions of years to develop and in the last 20 years or so we have increased the use 20 times over before we even leave school with the amount of use we give the hands.
I like the concept of a positive feedback loop driving human intellectual progress through an interplay between cognitive function and manual dexterity. I'm not sure it's accurate, but I do appreciate the elegance.
I can recall a speculative fiction story I read some time ago that postulated future humans evolving gigantic eyes and ears for processing the entertainment we bombard ourselves with constantly, and grossly overdeveloped thumbs for pressing the myriad buttons we use to interact with our electronic world.
Which brings up an interesting question - if every person played bass guitar, how would humans evolve? Longer and more dexterous fingers on the left hand, beefier thumbs and more powerful plucking digits on the right? Overdeveloped shoulders and upper-body musculature from supporting the weight of ever-larger extended-range basses? Deeper auditory range to appreciate the lower frequencies to begin hearing what are now sub-aural notes?
If you were a genetic engineer or cyborg surgeon, how would you design the ultimate bass player?
"Lefty" from the Flametrick Subs plays upright bass with no left fingers, and rocks the hell out.
I don't have any missing fingers, but when I was about 16 I snapped the tendons on the ring finger of my left hand playing Rugby, didn't even notice doing it until half time. The finger no longer bends at the top joint.
I spent around a year trying and trying to learn to play left handed which was very trying, then one day something just 'snapped' and it all felt perfectly normal to play lefty, and right handed felt weird.
The most amazing thing was that on the day everything changed I could no longer play pool, or shoot a gun right handed.
Hats off to those playing with missing digits.
