This
may mean that facial redness in females was once an involuntary
signal for optimal fertility but has since been 'dampened' by evolution
as it is more beneficial for females to hide or control outward signs of
peak fertility. Involuntarily signalling ovulation can prevent
longer-term investment from males. In primate species that advertise
ovulation, males only express sexual interest in females when they
appear to be fertile.
