Which explains democracy

Men who are physically strong are more likely to have right wing political views | Mail Online:

Men who are physically strong are more likely to take a right wing political stance, while weaker men are inclined to support the welfare state, according to a new study. 

Researchers discovered political motivations may have evolutionary links to physical strength.

It's an interesting article, but there is a political theory that democracy developed as a means of the weak to restrain and control the strong. It's been a long time since I read of it, so I won't try to develop it any further here. 

That theory is countermanded, though, by other hypotheses that democracy developed out of the "big man" more of tribal leadership in which the strong vied with one another for status based on how well they could provide staples such as food the for tribe as a whole. Anthropologist Marvin Harris described this in his book, Cannibals and Kings: The Origins of Cultures, although he does not tie it to the development of democracy.
