Did Lower Testosterone Help Civilize Humanity?

instant read


“A study of 1,400 ancient and modern human skulls suggests that a reduction in testosterone hormone levels accompanied the development of cooperation, complex communication and modern culture some 50,000 years ago.”

“He notes that lower testosterone is associated with social tolerance and cooperation in bonobos and chimpanzees, and with less aggression in humans. Cieri speculates that higher population densities could have triggered the shift towards lower testosterone levels, as people increasingly had to work together to succeed, and being highly aggressive became less advantageous.”

I’m not sure if this research will be confirmed in the future, but to me seems like a good sign, and excellent evidence.

This is a good sign because calls strongly for a new kind of leadership, one that is not the usual male-centered kind (competitive, antagonist, egoic, etc) and is instead more empathetic, compassionate, and unifying.
