By Michele Bachmann came out of the race for the Republican Presidential nomination, we are faced with an array of suspects in American politics-that is, a group of people who seem to spend most of their lives are bragging about how difficult they are.

Until Thursday, we have Rick Perry waxing macho about the number of executions he has overseen in Texas. We have Rick Santorum threatens to bomb Iran. There is a Newt Gingrich stated that people would boil down to be between “Newt and not Newt.” Even years Ron Paul started a campaign appearance with Darth Vader’s theme music, which he uses to emphasize how dangerous it would be Mitt Romney.

Like any zoology will instantly recognize, what we have here is a group of male primates who are vying for dominance.

If the attribute is a male Primate social dominant? Scientists who study animal behavior has been seen that question for a long time, producing some of the answers are complicated. But there are some very interesting insight in the recent papers that look at the dominant social Primate brains. Paper, by Jerome Sallet and colleagues at the University of Oxford, was published in the journal Science, and part of their research are most relevant for us troops in the Republic concern the rhesus macaque male.

First you must understand that the male rhesus macaque among most Dalai Lama-esque primates. They form a strict dominance hierarchy, linear, and the person who holds the highest position through aggression and intimidation-something primatologists calls domination system “despotic”. Male monkeys often witless and aggressive. (Not all primates is like this: there are other primate species where the male to female dominance thanks to the support of other collective, where it was the dominant female, and others where domination and hierarchy are concepts that are not relevant.)
