(106) Concealed ovulation

Basic Dimension


Number Archive


Concealed ovulation or hidden estrus in a species is the lack of any perceptible change in an adult female when she is near ovulation. Some examples of such changes are swelling and redness of the genitalia in baboons and bonobos. In contrast, the females of humans have few external signs of fertility, making it difficult for a mate to consciously deduce, by means of external signs only, whether or not a female is near ovulation. Fully "advertised" ovulation evolved in chimpanzees.

It might be while highly specific signaling of ovulation is absent, human female anatomy evolved to mimic permanent signaling of fertility.

Pawlowski presents the importance of bipedalism to the mechanics and necessity of ovulation signaling. The more open savannah environment inhabited by early humans brought greater danger from predators. This would have caused humans to live in denser groups, and, in such a scenario, the long-distance sexual signaling provided by female genital swellings would have lost its function. Concealed ovulation is thus argued to be a loss of function evolutionary change rather than an adaptation.

Bipedalism might be the key principle to concealed ovulation since it is a major physical difference between Australopithecus and Panini. 

The hypothesis of Pawlowski might be basically correct, in that concealed ovulation must be related to bipedalism. For the first australopiths, it might have given some difficulties to walk upright and to run quickly with visible signs of fertility. Also it might be pheromones spread by such females were smelled from a distance by predators. Definitely, predators would have seen and possibly selected fertile and weaker females from a distance. Furthermore we know lions are becoming mad from smelling ovulating women. So I think these kind of females might have been deselected from the population by predators. This means bipeds likely acquired concealed ovulation in evolution from about 7 million years ago.

According to the genetic split in head- and pubic lice (gorillas) it is estimated humanlike creatures started to loose body hair about 3 million years ago. Homo erectus (2 mya; 900cc) was like us and already lost most of his body hair. That's why he was able to run over large distances in the middle of the day hunting animals which were not able to sweat:

Because of their naked and humanlike bodies it is quite likely human female anatomy evolved to mimic permanent signaling of fertility from the time Homo erectus appeared on the scene. Indeed, the reason for permanent signaling of fertility likely was to replace the effects of concealed ovulation. But there are a lot of other possibilities. Of course males in the evolution systematically selected the most sexually appealing females.

The Myth of Adam and Eve

At some point in this overzealous selection of attractive women with prominent sexual characteristics it must have gone awfully wrong. Sexual culture threatened to change from inbreeding culture into outbreeding culture:

Women more and more followed their natural drive for genetic diversity and Eve seduced a male from another tribe (the Serpent). But also males like Adam - who did not like to copulate with his sister every day - were delighted of fresh females from other tribes. So Eve seduced Adam to enjoy himself since both were bored of each other.

Now time had come for 'religion' to take a conclusion from the time derivative and to correct the derailing inbreeding culture:

'Religion' let God say words of morality in the myth of Adam and Eve in paradise:

(An alternative interpretation is the Gihon, a river from the land of Cush, a mountain region in Iran and the Pishon is now a dry riverbed. All rivers ended in the Persian Gulf. Further, the story of Adam and Eve marks the transition from a hunter-gatherer to a farmer culture (Juris Zarins)).

The Myth of Paradise

The myth warned human beings (males and females) to cover their private parts for members of other tribes. No permanent signals of fertility may be visible. From now on they must use fig leaves and so 'religion' proved to be the steering on sexual culture by "God":


Genesis 2 and 3:

25And they were both naked, the man and his wife, and were not ashamed.

1Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?

2And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:

3But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.

4And the serpent said unto the woman, Ye shall not surely die:

5For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.[inbreeding and outbreeding].

6And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make onewise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. [Eve seduced Adam to outbreeding what was pleasant to the eyes and good for food].

7And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.

8And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.

9And the LORD God called unto Adam, and said unto him, Where artthou?

10And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself.

11And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat? [Tree of outbreeding]

12And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat.

13And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.

14And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:

15And I will put enmity between thee [your tribe] and the woman [her tribe], and between thy seed [your genes] and her seed [her genes]; it shall bruise thy head, and thou shalt bruise his heel. [hatred unites bedouin tribes in God, in sadomasochism]

16Unto the woman he said, I will greatly multiply thy sorrow [masochism] and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee [sadism].
Bereishit - Genesis

Bereishit - Genesis - Chapter 1

28. And God blessed them, and God said to them, "Be fruitful and multiply and fill the earth and subdue it, and rule over the fish of the sea and over the fowl of the sky and over all the beasts that tread upon the earth. "

Rashi's Commentary:

and subdue it: The“vav” [in וְכִבְשֻׁהָ is missing, [allowing the word to be read וְכִבְשָׁה, the masculine singular imperative] to teach you that the male subdues the female that she should not be a gadabout *(Gen. Rabbah 8:12), and it is also meant to teach you that the man, whose way it is to subdue, is commanded to propagate, but not the woman (Yev. Yev. 65b).

* Gadabout = a habitual pleasure-seeker.
((BD. Ed.): There was no God, but there was a much older exogamous culture of outbreeding in which women were respected (Homo erectus (2 mya; 900cc))

17And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life; [all day long fresh woman slaves from other tribes and get off my Camp with my terrible experiments on humanity]

18Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;

19In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

20And Adam called his wife's name Eve; because she was the mother of all living.

21Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them.

22And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever: [live forever in the illusion of genetic immortality by inbreeding]

23Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken. [They were sent away from Camp Paradise, since it is a lovely myth, but in fact Eve was stoned and Adam hanged].
24So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.


22And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:

Later in the evolution of inbreeding cultures, females only were visible to the owner of the object. Males threw sacks on their heads so nobody could see it was a human being anymore. And guess what, females felt delighted to be real objects:
