BIPEDALISM MODEL EVALUATOR   Home  
Evaluative Framework      
1 "Darwinian"      
1.3 Not Teleological (DNT) A key aspect of Darwinian thinking is that the selection for a particular trait must be present at each and every stage in its evolution. There is no ‘end goal’ in mind and so teleological factors must be discounted.

Models suggesting habitat compulsion as a driver for bipedalism, as opposed to some behavioural aspect that could be argued to favour humans., were judged best here.
