Analysis of Evolutionary Debunking Arguments by Greene and Singer

Both Greene and Singer essentially are advocates of the same idea, the idea that discards deontology using evolutionary debunking arguments. Their argumentation, however, differs. Greene decides to use scientific data and data from psychological experiments and interprets it using explanations that reinforce his hypothesis. Singer, on the other hand, choses to talk more in principle as to why his hypothesis is a more reasonable one, and only uses scientific evidence at a handful of occasions. I have reconstructed both approaches one by one and then presented an evaluative comparison in the end.
