Perhaps not as much as you think. Mathematica is fundamentally a term rewriting system, a more general concept than the lambda calculus behind Lisp. To be sure, the easiest thing to express as term rewriting is the replacement of a function invocation by its body (as in the lambda calculus), but Mathematica can do more complex things, some rather strange from the lambda calculus point of view. Consider f_[whoCalled]^:=f Sin[whoCalled] which yields Sin Very alien to Lisp!
