positions of power. It is not a black and white situation. You are correct current belief in the natural sciences, it is know Wives want sex tonight Argentine that in the animal kingdom that monogamy is not the norm. Homo sapiens are genetiy predisposed to attempt to procreate with as females as possible and females are predisposed to choose only the healthiest suitor. The successful ones are ones with the best genes for the particular environment they find themselves in. This is all good and well explanation but for one fact, we have a that allows us to choose not to act on our evolutionary urges. We created a society with certain rules built in it so that the people in that society could exist without physical conflict. These people in positions of power are not so much cheating based on their evolutionary urges which your theory alludes to but mainly from the adage of power corrupts and absolute power corrupts absolutely. These people believe from the heady brew of power that they not only deserve but also are above such societal laws, Even what I have said is not the whole truth because it is much more complex when other factors are brought into the mix. Some people are weak of mind and indulge in their urges without care of the pain they cause. But I would think that people in power are there because they are not weak but strong of mind so the genetiy predisposition does not explain it in most cases regarding these people. Be careful when you use words like "in all cases". Your explanation has the odious possibility of giving an excuse for these people not to take responsibility for their choice to choose to cheat. With people in power it is a different set of motivators for their actions. There are some not intentional seeking sex but ended up cheating nonetheless. Oh one thing, rethink your last sentence it allows for far too interpretations as well as being too simplistic.
