That traces the erosion of topsoil in societies. I don't have the author, but it's a fascinating account of how societies evolved around the quality of soil-- which as we all know, gets it's leeches out nutrients when overused or used incorrectly. This is not a feminist book, it's simply a historical account of dirt. It's fascinating stuff.
I have a problem with the "hunter" trope, first it was very dangerous, and not always successful, the gatherers held the family group together. Second, I want to know why everyone is so sure women were NOT hunters.
It fascinates me that the assumption the we immediately "waged war" against competitors, instead of going for cooperation, of course we may have, patriarchy may not have started until the rise of the city state.
Anyway, did you see this? I'm not sure I buy it but I'll have to read the study
Drop in testosterone levels accelerated human prosperity, a new study suggests.
It might be a man's world, but femininity laid the foundation for modern civilization, a new study has found.
Modern humans evolved around 200,000 years ago. However, humans started using tools and making art some 50,000 yearsago. The latest study by Duke University researchers explains this gap in human civilization history.
The team said that lower testosterone in humans led to people being nice to each other, which in turn led to the development of civilized societies.
"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," said lead author Robert Cieri, a biology graduate student at the University of Utah who began this work as a senior at the Duke University.
The shift in temperament can be gauged from the changes in facial structure. Reduction in male hormones led to softer facial features - rounder heads, less prominent brows.
For the study, researchers analyzed 1,400 ancient and modern skulls. The team found a link between reduction in testosterone levels and growth of civilization. The researchers aren't sure whether humans had less testosterone circulating in the body or had fewer receptors for the hormone.
