___ man is a type of primitive man named after a valley near Düsseldorf in Germany (11)

I believe the answer is:

neanderthal

(Other definitions for neanderthal that I've seen before include "Extinct type of human" , "Hominid discovered in Europe" , "Sort of very old man" , "Type of primitive man" , "German valley" .)

I've seen this clue in The Independent.
