BIPEDALISM MODEL EVALUATOR   Home  
Evaluative Framework      
       
1 "Darwinian"      
1.2 Sexual Selection (DSS) This factor is included because it is a fundamental aspect of Darwinian natural selection theory. Clearly any model that provided a robust case for improving sexual selection through bipedalism is judged favourably here.

A few models based on sexual selection (e.g. Lovejoy's "Provisioning" hypothesis) were judged highly by this criterion but most were judged neutral.
