Concealed Ovulation
Updated:Concealed ovulation refers to the absence of obvious physical signs when a female is most fertile. In humans and some other primates, it's difficult to determine when ovulation occurs without medical tests. This is in contrast to many other mammals where females display clear signs of fertility, such as changes in behavior or physical appearance.
Additional Information
Concealed ovulation is believed to have evolved in humans for several reasons:
- Promoting pair bonding: It encourages males to stay with one partner, as they can't easily determine when she's fertile.
- Reducing male competition: Without obvious fertility signs, there's less direct competition among males for fertile females.
- Female choice: It gives females more control over mate selection, as males can't easily identify the most fertile time.
Some scientists argue that concealed ovulation played a crucial role in human evolution, contributing to the development of long-term pair bonds and complex social structures.
Examples
