But what was this "function"? If the forelimbs did regain function after a
period of atrophication, >why did they remain so small?
Probably because claws are easier to adapt than bones. They don't have any
surrounding musculature or circulatory system, you're really just tinkering
with a cuticle. They're more cost effective too in terms of material
(keratin vs. bone, blood, etc.). So if claws can be adapted to the given
task more quickly, they ought to reach optimum function before selection
really starts working on bone et, al.
If you need "sharp points two feet away from the body" does it really matter
how they get there?
