Jeff, quit while you are ahead. You already won.
And about the savanna thing... it's ironic, tonight I watched the premier of a TV show on the Discovery Channel called "How the Earth Made Man." The theme is how we evolved to what we are based on the earth's changing environment over millions of years.
There was a short segment where subjects were shown landscape photos and asked which place they would rather live in. They all picked a wide open, green rolling hills scene, and rejected a jungle, a desert, and a snow covered mountain. Strong echo of the Falk/Balling abstract linked above.
But the important point is they were asked where they wanted to live, not which scene appealed most to their asthetic interest, and certainly not which photograph was the "best". (All the photos were artistic and excellent quality, by the way.)
The researchers used this "experiment" to validate their theory that we humans are genetically wired to favor a location that has the least predators against us, and the most bounty for us. Unfortunately, the Falk/Balling abstract does not mention this detail.
And about the perfect face thing... There is a lot of solid research about that. Several years ago, the BBS aired a mini-series called "The Human Face" that referenced a lot of the research (http://en.wikipedia.org/wiki/The_Human_Face
Here's another link about the analysis of the perfect face. Unfortunately, the site is pretty messed up and not maintained.http://www.beautyanalysis.com/index2_mba.htm
