The finer motor capabilities look to be a combination of biomechanical adaptations and control (neural) adaptations. There is no point in having one without the other, so it would not be reasonable to conclude that these could evolve without an intelligent designer, even without know the further details of the complexity involved.
All good points. I’m off to go sailing off the coast of sunny...err...partly cloudy S. California. I will be back to post some more once I am done enjoying and marveling at God’s wondrous creation! :o)
