The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.     
I have almost no regard at all for convenient rape allegations, especially when they are more than 10 years-old, come from California (where Follywood and its trance-induced suspension of disbelief has more influence than truth, justice or common sense) and only arise when someone who threatens the politics of Follywood, its sordid secrets, and it’s political allies (ie: Obama or Clinton) appears on the national scene. Case in point: roughly 50 Follywood slugs came forward and accused Bill Cosby of all sort of infamnia, but not a single one of them ever ended up in court and one even came close to even bothering to prove the allegations. The first to open her plastic-surgically altered suck hole was the coke whore Janice Dickenson, who BTW accused Sly Stallone of being the father of a child she had with a failed actor turned dope dealer. (Wasn’t it too bad for her bank account that the paternity test disagreed with her psychotic view of reality?) IT only got worse from their. Even the case in Philly has not resulted in any conviction. IMHO: all of this was assasination by sheer repetition of propaganda; as Goebbels “The Clown” is noted to have said: A lie told once remains only a lie, but a lie told a thousand times becomes the truth. Follywood and the media are nothing but propaganda whores for its allied politicians. Cosby’s assassination was OBama-Brand payback for the fact that Cosby was critical of him since the first day he took office. Lastly, during the 70’s and 80’s it wasn’t only popular to give girls quaalude in Follywood, it was going on all over the damn country. It was like the first “roofie”. Then came cocaine, and there were no shortage of “starlets” who gave all for its charms too, and will claim they were victimized only because they lost their limelight. Assassination by sex and drugs is one of Follywood’s tools; they know how to use it well, imo the proof of that is in Dr. Phil’s video, which BTW has NOT been taken down: Anyone who wants to view it – just go directly to , (do not click on the link I provided in my prior comment) get on Dr. Phil’s channel and look for it. I think it will be there for quite a while because if you study the credits you’ll find that it was produced by Dr. Phil AND HARPO PRODUCTIONS. I doubt any Follywood, Washington or NY pervert(s) has what it takes to buck Oprah when it comes to child rape, sex slavery and murder. I also have little doubt that at least a few of sadistic cowardly adherents of these practices are sadistic misogynists.
