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.
