This is the question that I find the most fascinating, and I am glad to see that I am not alone. If a new people did arrive, did they adopt some of the cultural practices of the people they displaced? Did/do humans tend to recognize places of spiritual importance and continue to honor them out of respect for/fear of the ancient gods of a place that they are new to? Displacement with or without competition is a major feature of biological evolution, it would be surprising if it _didn't_ apply to humans.
