'The study of human evolution has tended to look at things from a male perspective,' said senior study author Professor Athena Aktipis, associate professor of psychology at Arizona State University in the US.
'Even adaptations specific to females – like their social behaviour and concealed ovulation – have been viewed in terms of how males shape them.
'Our computational model shows female sociality is about much more than securing male investment.'
Human females are considered to have concealed ovulation because there is no outward physiological sign, either to a woman herself or to others, that ovulation is occurring.
As a result, women of today rely on helpful aids like charting, test strips, apps or wearable tech to identify periods of fertility.
