Queensland researchers have demonstrated that teenage girls in Australia are as aggressive as boys.

They have shown that girls are starting puberty earlier which results in boosted occurrences of aggressive behaviour when entering teen years.

According to the researchers, fourteen-year-old girls were just as likely as boys to become involved in threats, fights, and theft, which reinforces the idea that teen girls are increasingly imitating their male friends.

Jake Najman a sociologist with the University of Queensland and the lead author of the study claimed that an increased rate of obesity in children was causing puberty to be experienced at earlier ages.

He said the increase rate of aggressive behaviour was also experienced in teenage boys.

Professor Najman explained that further study need to be carried out in order to find the reasons why some young women were beginning to behave more like males.

He said that society’s reflex to explain male aggressive behaviour by the presence of testosterone is not worthy any longer since females are experiencing similar signs.
