An agent-based model of the female rivalry hypothesis for concealed ovulation in humans
Nature Human Behaviour, 2021After half a century of debate and few empirical tests, there remains no consensus concerning why ovulation in human females is considered concealed. The predominant male investment hypothesis states that females were better able to obtain material investment from male partners across those females' ovulatory cycles by concealing ovulation. We build on

The Evolution of Concealed Ovulation
The American Naturalist, 1979Several hypotheses have been proposed to explain the occurrence of continual sexual receptivity and concealed ovulation in human females. In view of the large number of benefits that would accrue to females if they could sense their own ovulation, these explanations appear insufficient to explain why ovulation is concealed from females as well as from ...

Evolution of Concealed Ovulation in Vervet Monkeys (Cercopithecus aethiops)
The American Naturalist, 1987Few systematic attempts have been undertaken to test hypotheses concerning the functional significance of concealed ovulation or prolonged sexual receptivity in extant populations of nonhuman primates. Here, evidence is presented that female vervet monkeys (Cercopithecus aethiops) successfully conceal the time of ovulation from males.

The evolution of concealed ovulation and self-deception
Ethology and Sociobiology, 1983Abstract Humans are strikingly unusual among primates and most mammals because females do not reveal their critical period of ovulation. This phenomenon, concealed ovulation, can be best understood in the perspective of evolutionary theory. It would seem that stimulus signs are essential to reproductive success because activities would be drawn to ...

Sexual selection, paternal care, and concealed ovulation in humans
Ethology and Sociobiology, 1981Abstract Changes in the social structure of early humans greatly enhanced the potential for paternal care to contribute to offspring success. Selection therefore favored females who mated with more paternal males. Since paternal care limits mating effort, males least successful as polygynists would have the most to gain by paternal behavior, while the

Sexual cyclicity and concealed ovulation
Journal of Human Evolution, 1986The disappearance in human evolution of mid-cycle estrus, present in infrahuman primates, is considered in relation to studies of periodicity of sexual desire and activity in the human female. Evaluation of investigations suggests the presence of a bimodal pattern of elevated sexual arousability, with peaks in the premenstrual phase and around ...

The American Naturalist, 1993
Under the assumption that the absence of visual signs of ovulation (usually termed "concealed ovulation") is an adaptation in primates, there are two main hypotheses concerning the evolution of this trait: it is a means to promote paternal care and increase paternity confidence, and it is a means to confuse paternity issues and thereby improve male ...

Concealed ovulation and clandestine copulation: a female contribution to human evolution
Ethology and Sociobiology, 1993Abstract Concealed ovulation in human women has generally been interpreted to have evolved within an a priori multimale social setting. Because there is evidence that hominids passed through an evolutionary phase with a unimale social structure, alternative explanations are required.

Is Human Ovulation Concealed? Evidence from Conception Beliefs in a Hunter-Gatherer Society
Archives of Sexual Behavior, 2004Several researchers have suggested that ovulation may not be concealed in humans living under natural conditions with minimal hygiene. Because measuring coital frequency in such a population is problematic, I tested this proposition indirectly by asking Hadza hunter-gatherers of Tanzania when a woman can get pregnant.

‘Concealed Ovulation’ and Sexual Signals in Primates
Folia Primatologica, 1992The absence of conspicuous sexual signals in some primates, particularly humans and vervets, has been interpreted as evidence that females of these species are ‘concealing’ ovulation from males. This conclusion is unjustified: the null hypothesis of no adaptation, that the absence of conspicuous sexual signals has resulted from the absence of selective
