Yes. There are more parts in the human body, and more kinds of interaction
between parts.

I don't know what you mean by "limits of change", but yes there is a big
difference in the processes of ice formation and human evolution. The main
similarity is that both are examples of localized decreases in entropy,
allowed by the second law of thermodynamics because they take place in
open systems.
The difference, of course, is that ice formation does not involve inherited
variation and natural selection.
