Explanation:

Homo habilis is an extinct hominid that lived in Africa, in the Gelasian and Calabrian ages (early and mid Pleistocene), 2.4 million years ago. The discovery of this species is due to Mary and Louis Leakey, who found the fossils in Tanzania, Africa, between 1962 and 1964. When it was discovered it was considered as the oldest species of the genus Homo, a position later occupied by H. rudolfensis.

His name means "skillful man" and refers to the finding of lithic instruments probably made by him. There have been detailed studies of the skeletal remains of his hands to verify if it would really be possible that this Homo had made them. The scientists concluded that it was capable of making pressure grip to perform the necessary manipulations in the manufacture of stone utensils; Probably, it was an opportunistic carnivore, that is, a scavenger, but it is an extreme that we do not yet know.

social contract theory basically says that all individuals are born equal, and provided a god given right to consent to be governed. american government is based of this

thomas hobbes and john locke said that we are selfish, individualistic, and constantly at war with each other, therefore we need to be controlled. 

government is defined as the legitimate use of force to control human behavior within territorial boundaries, here comes in hobbes and locke.

hobbes takes the part about controlling human behavior. while locke takes the part of legitimate use of force, since force is not legitimate unless there is consent of the people. 

there are basically 3 goals of the government: 1) maintain order by protecting life and property. 2) providing public goods, those which are typically not provided by the public sector, such as roads and education. 3) promote equality be it political, opportunist or outcome equality.
