Probably quite a bit, there are dedicated circuits in the temporal lobe of the brain, circuits whose function to pick out facial features from visual stimuli. But I don't think this makes the perception of faces in landscapes or stones invalid in anyway. The same bits of brain would have been highlighting these features in the minds of the builders of the monuments. You could argue that this would have had a gretaer effect on the minds of our ancestors than it does on us modern types.

And that is one heck of a good picture Moth got there. Clear as a bell. I'm nterested by the fact that so far, neurologists go on about facial recognition templates in reference to frontal views, but the pics like that add evidence to the idea of templates for profile recognition, and for all of the body, not just faces.
