idea started with research findings published in Nature, a scientific
journal, in 1971. A researcher called Martha McClintock studied the
menstrual cycles of 135 women in an American college.
"[McClintock] found that the onset of the date of menstruation was more
similar among friends and roommates than among random pairings of women,"
says Alvergne.
Dr McClintock hypothesised that this was because the women who were spending
time together had the chance for their pheromones to affect each other.
And why would this happen? The most prevalent theory was that it was an
evolved strategy among females to co-operate with each other - to stop
becoming a kind of harem for a single dominant man. |
