Adaptations in females for regulating mate choice around ovulation
Natural selection is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this can be referred to as the survival of the fittest that enable species such as mankind to adapt to specific environmental pressures for survival and reproduce in order to maintain favourable genetic traits in succeeding generations. The adaptations in females for regulating mate choice around ovulation suggests that mammals, particularly human females invest heavily in parenting and are choosy when it comes to mating. Broadly, the preferred mate choices females make are predicted to have evolved to exploit the reproductive potential and reproductive investment including the ability to invest in growth, development, and later social and reproductive competencies of offspring and the potential genetic benefits that the offspring will confer. In many mammalian species, the period of highest fertility just before ovulation is marked by dramatic increases in female sexual behaviour and attractiveness. For example, other female species solicit males for sex exclusively within the fertile phase of the cycle. For chimpanzees, our closest relatives, females have sex throughout the cycle, however they have pronounced genital swellings indicating that they are ovulating, thus enticing males to copulate with them much more frequently during the time of ovulation. In contrast, human females are sexually active throughout the cycle as well but they lack extreme changes, generally accompanying the...
