I am not interested in knowing answers discussing the way I hold a cup of coffee or a pen but bigger perspectives as to how the way of doing activities would affect the world (read: universe) at large.
I would love to know which combination of fingers if we didn't have (one from each limb) would affect our life least and which combination would affect the most?
How would it affect the world if all the 5vers were 4ers?
What are the actions we can or cannot do with less than 5 fingers? If we create a robot or have the power to redesign the human body how important would it be to stick to the 5-finger design?
When possible, any research on the increased dexterity of 5 digits over 4 or less should be included.
