While, one part of the study is true (we women do prefer those features in a man) but to say that "woman have a natural inclination to cheat" is offensive and is b.s.
Yes, if I were single and wanted a baby, sure, Id go find a guy that looked like Peyton Manning and do the bump and grind real NFL style, but would I cheat on my husband just to ensure my babies health? No, I would have never married a wimp in the first place and your obvious lack of trust in womens loyalty will hurt ya, pal.
Don 't take what I said personally, if anything blame researchers like Randy Thornhill, he is as much to blame for these findings as Darwin is for the theory of evolution. You can also blame Richard Dawkins for his selfish gene hypothesis. Oh, and here is a link to one of the studies on this-

As far as me personally, I know that if a woman decides to cheat on me there is nothing I can do about it anyway, so no point in being jealous. Of course if I find out about her clandestine sexual activities I would be hurt like just about every other guy would be.
To be fair, I also think that men are naturally inclined to cheat. Whether or not one chooses to follow their natural inclinations is based on their morals and ethics, which is what IS different between us and animals. We can think beyond our instinctual desires and understand that some things that we are naturally inclined to do may hurt other people we care about. Unfortunately I think there are alot of selfish people our society, when given the choice, still choose to behave like animals without consideration for others feelings.
