Georgiansilver, you're failing to see that the evidence all supports the theory, kind of like evolution is still a theory that is supported by, but not proven by, evidence.
NO piece of evidence will prove ANY theory. Plate tectonics, gravity, are all Theories supported by, but not proven by, all their evidence.
There are no data collected in biosociology that support any OTHER theory. There are no data collected in biosociology that are NOT explained by this theory.

Like it or not, the "theory" is the accepted model of today. There are no competing SCIENTIFIC theories. There may be competing religious "theories" (sic) like ID, but I wouldn't believe that of you, personally, so far.
