Bronze Age women travelled hundreds of miles to start new families while men stayed at home, a new study has shown.
Researchers in the German city of Munich also suggested they helped the spread of new ideas, knowledge and objects.
They came to the conclusion after examining the remains of 84 people buried between 2500 and 1650 BC.
Their findings s h owed that over the 8 00 year period there was a noticeable pattern of women travelling up to 300 miles from their birthplaces to start new families, while men stayed in their place of birth.
This "patrilocal" pattern, of couples settling in the male’s birthplace spanned from the Neolithic period into the Early Bronze Age.
Re s e arch lea de r, Philipp Stockhammer of the Lu dwig Maximilian University of Munich said that examining their molars had allowed them " to view the immense extent of early human mobility in a new light."
He added: "At least part of what was previously believed to be migration by groups is based on an institutionalised form of individual mobility."
The research focused on groups in the Lech Valley area of Germany and the findings were published in the PNAS journal.
The study showed that individual mobility was a key part of human life as far back as the second millennium.
Dr Stockhammer said this "was a major feature characterising the lives of people in Central Europe even in the 3rd and early 2nd millennium."
