Therefore it was considered when the present of the forest of Africa was no longer there with the right resources, grassland replaced this. Whereby when the resources were scarce in the forest ground was not “ hominids would have used their energy much more efficiently once bipedalism freed their hands to pick up food “(Larsen, 2013 p.237).Having said hominin ancestor is a knuckle-walking quadruped and this allowed their dietary aspect to change when being able to walk on two legs. A con to this is there have not been any pieces of evidence to show what resources were actually available when going from all fours to land. The theory of long-distance walking on two was proposed by Roman and McHany (1980), stated walking allowed them to be more energetically efficient than quadrupedalism which can be considered their close related ancestor of chimpanzees. Rodman and McHenry (1980) also stated that hominin biped actually more efficient at walking speeds than classic quadrupedalism and more efficient than chimpanzees.When all organism are presented with a net of energy, when to say any way of trying to reduce energy especially in bipedalism that is considered to have done more movement than normal to help them survive, considering a great natural selection. There comes a weakness again to Rodman & McHenry theory which suggests that there was no energetic turning point that crossed for early hominoid ancestors furthermore is why bipedalism not took place or evolves in other apes, why must it be specifically chimpanzees in terms they were more energetically efficient to do
