The importance of being able to adapt in life is vital especially during the ancient days of early life. This paper discusses the adaptive strategies of early ecology. The human behavioral ecology (HBE) began with the application of optimal foraging models of hunter-gatherers with resource selection and land use. Evolution ecology studies have been the adaptive design in ecological context. The HBE will be a method that will gain interest of those who are interested in ecology. How do these methods differ? The best method is by combining all of these together. "Although EP,DIT and HBE are often portrayed as competing alternatives, a case can be made for viewing them as complementary" (Winterhalder and Smith). If a person had to choose one, it would probably be the HBE because it combines the study of past ecology with the observable behavior.
