GP operates at the function/terminal level of a functional programming
language, evolving code through breeding and mutation of actual programs.
The particular set of functions and terminals are used as raw materials for
generating programs to solve a given problem.

My understanding of GA is that it operates at a lower level, defining
genotypes that are passed to some other program to be expressed.

There's a Ruby GP implementation at
http://akimichi.homeunix.net/~emile/aki/program/gp/

though the site appears to be down right now.  I did play with it some
months ago, and it's quite nice.
