The historical facts have showed that the modern humans evolved around 200,000 years ago. However, the humans began using tools to make art forms or hunt approximately 50,000 years ago. But why the huge gap.
The researchers at the Duke University tried to find out the reason behind this massive gap and decode the missing links in the history of human civilization.
According to the researchers, the new study showed some connecting link between the changing structure of human skulls and lowering of testosterone levels, that they say was responsible for the development of civilized societies.
Lead investigator Robert Cieri, a biology student at the University of Utah who began working as a senior at Duke University, said, “The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament.”
The researchers say femininity was behind the foundation for modern civilization. They also said that the lower testosterone levels made humans more civilized and this led to the foundation of civilized societies.
For the study, the researchers involved analysis of 1,400 ancient and modern skulls. They found that there was a connection between lower testosterone levels and human civilization.
According to the researchers, they studied the human skull because the changes in their attitude can be deciphered from the changes in the facial structure. The reduction of hormones in male community led to softer facial features including less prominent brows and rounder heads.
“If we’re seeing a process that leads to these changes in other animals, it might help explain who we are and how we got to be this way,” Hare said in a statement.
The researchers concluded that we may be living in the male-dominated world but the dropping testosterone levels accelerated human prosperity and added a new chapter in the history of mankind.
The research paper was detailed under the title “Craniofacial Feminization, Social Tolerance and the Origins of Behavioral Modernity,” in Current Anthropology journal on July 1.
