Monogamy is observe in just over a quarter of primates and only around 3–5 % of mammals , overall . How it evolved in humansis still the field of intense public debate , and with good intellect . “ Monogamy is a problem , ” University of Cambridge zoologist Dieter Lukas once put it . “ Why should the male keep to one female person ? ”

Females , with their extended gestational period and finite strong-arm resource , can only give giving birth to healthy issue sporadically . No such biological limitation be in males , who can , in theory , sow in their seed as far and wide as they please .
