female dogs and big balls

Will someone cut my bangs?

     Science News, 5/21/11, published a story "Great Danes minds don't think alike."  It reported the results of a University of Vienna study of 50 pet dogs, including poodles, Australian shepherds, golden retrievers and mutts.  The experiment was to test if dogs noticed what one-year-old human babies see, when a ball inexplicable grows.
     A tennis ball was rolled along the floor until it went behind a screen.  Then a larger ball would appear on the other side.
     Conclusion: female dogs noticed -- and stared at the large ball for longish periods of times.  Male dogs stared at either the big or the little ball for about the same amount of time.  And the scientists can't figure out why.  They could not figure out any strong evolutionary pressure which would cause female dogs to stare at larger balls for longer periods of time.
     Well, I have solved their problem: First, people at the University of Vienna have too much time on their hands and should stop playing with dogs or balls.  Second, there is obvious evolutionary pressure for females to stare at large balls, something human females do all the time.  If I have to explain the reason for this, those folks are truly lost and should take a sex education class.
