oh the irony!
"evolute" has damn near an opposable big toe.
I think we all have feet capable of competently manipulating objects. It's not just a matter of having long toes. My friend's daughter has been picking up toys with her feet since she was two, and she has tiny little baby toes. Perhaps you all have just never tried to develop your natural abilities to grasp objects with your feet... though I'm not sure why not.
