Shades of meaning

In “Going Coastal: Sea cave yields ancient signs of modern behavior” (SN: 10/20/07, p. 243), researcher Curtis Marean refers to Stone Age people using a reddish pigment for “body coloring or other symbolic acts.” What reason is there for jumping to this conclusion? As with cave painting and figurines, there seems to be an undue emphasis on symbolism and a supposition that everything has to have “meaning,” particularly a religious or protoreligious significance.
