Actually, you typically don't use all the dexterity of a five-fingered hand for most tasks. Opposing-digits gets you 90% of the way there, which is why when you finally start using fingers independently (say while playing the violin), a large amount of time is spent getting around the learnt 'synergies'. Unclear why we actually evolved fingers in the first place (balance ?).
