A Wisdom Archive on Concealed Ovulation - Conclusion

This apparently "minor" change in humans from other primates, the concealing of fertility, may have major and wide-ranging effects on the composition of human society, encouraging pair-bonding, families and tribes, child nurturing by both parents, division of labor based on sex, taboos on infidelity and, according to some theories, also paving the way for jealously, lying, infidelity, and fratricide. ...

Also unlike most other animals, human females are fertile all year rather than just at certain times of the year. Unlike other animals which are fertile all year, scientists do not believe that humans evolved this trait in order to allow greater numbers of offspring to be produced. In a hunter-gatherer environment, a human female can only support about one offspring every four years. Until the beginnings of agriculture, breastfeeding and low nutrition levels caused a natural fertility suppression. Concealed ovulation - T ... Including:

The menstrual cycle is the set of recurring physiological changes in a female's body that are under the control of the reproductive hormone system and necessary for reproduction. In women, menstrual cycles occur typically on a monthly basis between puberty and menopause. Besides humans, only other great apes exhibit menstrual cycles, in contrast to the estrus cycle of most mammalian species.

According to one theory, in a hunting/gathering society without agriculture, the role of a male courting a female would play out as follows: the male's sexual interest in the female keeps him around her continuously. The male would give the female and her offspring (even if they are not his own offspring) foods that are more difficult for the female to acquire alone, such as the highly concentrated protein and fat in the meat of large animals, in "exchange" for her consent to sexual activity. Due to concealed ovulation, the male never knows ...

The most frequently cited theories about the origins of concealed ovulation as a reproductive strategy focus on the secondary function of sex as a reinforcement of social bondings. Human children require significant care far longer than most animals. The stresses of child-bearing and child-rearing create a need for paternal support during the process.
