BIPEDALISM MODEL EVALUATOR   Home  
Evaluative Framework      
       
2 "Ecological"      
2.5 Applies to Both Sexes This criterion simply asserts that a model promotes bipedality in only one gender then it is weaker than a model that promotes bipedality in both.

Half of the models were judged 'good' by this criterion and 3 based on single sex ideas were judged very poor. The rest were rated accordingg to how plausibly the behaviour was likely to be done by both sexes.
