Explanation:
One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.
Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.
It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
