Cave paintings found across the world showing men having sex with animals suggest that our ancestors were rather promiscuous.
It seems that hunter-gatherers, after roaming all day long through large areas of land to find animals they could kill, would sometimes f..ck their freshly killed prey.
This practice survived for thousand of years in some traditional societies.
For example, it is reported that hunters of the of the Salteaux Canadian Indian tribe had sex with moose and with female bears they have shot, before the animals get cold (Menninger 1951).
How was circumcision invented?
Recent study showed that men who have sex with animals may have an increased risk of penile cancer.
The study, led by urologist Stenio de Cassio Zequi in San Paulo, looked at men from rural Brazil. Of the 118 men with penis cancer, 45% reported having sex with animals such as horses, cows, pigs and chickens.
This begs the question – if our ancestors were regularly engaging in copulation with animals, perhaps penile cancer was rampant among primitive men.
This could suggest that circumcision was invented as a way to prevent penile diseases.
After all, iconographic evidence put circumcision well into the Paleolithic period, making it the oldest known surgical procedure.
In the stone age cave paintings, many circumcised male images were found, but Is it really possible that primitive men realized on their own that removal of the foreskin from the human penis could help them battle penile diseases?
Ancient medicine intuition
Well, ancient practices in some cases were very intuitive.
For example, long before the emergence of the Old Testament and the Qur’an, people in the Middle East had largely cut the pork from their diets.
Today we know that pork contains high levels of cholesterol, an increase of which in the bloodstream leads to an increased likelihood of blocked arteries. The fatty acids in pork are also of an unusual formation, when compared with the fatty acids in other types of food, which makes them more easily absorbed by the body, thus increasing cholesterol levels.
Pork meat and pork fat contribute to the spread of cancers of the colon, rectum, prostate and blood, but ancient people couldn’t have known all that definitely, but they still removed pork out of their diet – showing us that sometimes primitive men intuitively knew the right answers for some medical problems.
