Map and Reduce are two primitives of functional programming that had particular use in Lisp. Consider that those primitive are also implemented in Python ( Guido van Rossum suggested to remove those primivites in Python 3000 http://www.artima.com/weblogs/viewpost.jsp?thread=98196 ). On the other side, consider that Peter Norvig, Lisp guru started as Research Director @ Google in 2001. That may have affected somehow to the development of that paradigm.
