According to a group of anthropologists headed by Dr Brian Hare of Duke University, a decline in testosterone levels about 50,000 years ago led to the development of advanced tools and art.

There are a lot of theories about why, after 150,000 years of existence, humans suddenly leapt forward in technology.
Around 50,000 years ago, there is widespread evidence of producing bone and antler tools, heat-treated and flaked flint, projectile weapons, grindstones, fishing and birding equipment and a command of fire.
“Was this driven by a brain mutation, cooked foods, the advent of language or just population density?”
Dr Hare and his colleagues argue that human society advanced when people started being nicer to each other, which entails having a little less testosterone in action.
“If prehistoric people began living closer together and passing down new technologies, they’d have to be tolerant of each other. The key to our success is the ability to cooperate and get along and learn from one another,” said Robert Cieri, a student at the University of Utah and the first author on the study published in the journal Current Anthropology.
