"Applying the principles of art to golf course design obviously contributes a sense of well-being to those golfers who are playing with the objectives of relaxing and enjoying themselves. On the other hand, touring professionals out to win concentrate on getting the ball into the tiny hole and may be forced to ignore beautiful surroundings. Yet one suspects that the beauty of a course provides even them with relaxation during periods of extreme stress. This sense of well-being may be somewhat similar to the feeling of security that arises in people from having mowed lawns surrounding their dwellings. Perhaps that feeling harks back to a need to see one's prey or enemy at a distance through a focal point past trees and over short grass. An evolutionary biologist has told the authors that most golfers play the game in order to relax and enjoy themselves, and there may be biological reasons that the landscape design of golf courses contributes to these feelings. The human species spent most of its history as hunter-gathers in habitats like those of golf courses, only much larger-specifically, open savannas, grasslands with scattered trees and bushes that supply nutritious food (browsing and grazing animals, berries, seeds, buried roots), shade from the sun, refuges where we can stalk prey and hide from predators, and frequent changes in elevation than enable us to orient in space and thus find out way to remembered places that provide important resources, such as food, water, and shelter. Evolutionary biologists and psychologist, such as Orians and Heerwargen, have found a preference for such savanna-like landscapes across human cultures, ad they suggest that it reflects an evolved learning bias that allowed us to psychologically adapt to living in this habitat. We could invent challenging golf like games in which balls are hit through habitats that are much less expensive to maintain, such as dense woods, open land that is flat and barren, or a desert, which would be one continuous sand trap! But we don't , and part of the reason for not doing so is that such landscapes are just not appealing to the majority of our species and do not provide that sense of well-being that golf architects strive to create."
