He may have come down from a tree, but prehistoric humans did not stop swinging.
New studies of Stone Age humans believe that they make love not for reproduction, but for fun.
In primitive societies, practices ranging from bondage to group sex, dress-up and use of sex toys are common, and this is a way to build cultural connections.
According to this study, 30,000-year-
An old statue of a naked woman-
Venus of William Dov-
An equally ancient stone penis found in German caves provides the earliest direct evidence that sex is more important than a baby.
Timothy Taylor, a reader of archaeology at Bradford University, reviewed dozens of archaeological findings and evidence of scientific research for his research.
"It is generally believed that past sexual activity was mostly heterosexual and that reproduction could be challenged," Taylor said . ".
He believed that the one-husband system was only established as a hunter.
Collecting society to engage in agriculture and settling in the home has made the social role of men and women more fixed.
Experts believe that studies like Taylor may help to overturn the wrong assumption that sex is the most natural form for breeding purposes.
Petra Boynton, a relationship consultant and health lecturer at University College London, found the study "refreshing ".
"So many evolutionary theories have promoted the idea that humans, especially women, are pre-set to be monogamous, but this is usually just putting science above it.
She said: "There is an existing social point of view.
Taylor's study, published by Haworth publishing house in the manual on the evolution of human sexuality, said that human attitudes towards sexuality stem from complex interactions of physical and mental development.
By contrast, modern people, who showed up about 300,000-
100,000 years ago, apes had very small male genitals, no female breasts, and hair.
But it's easy for them to distinguish between sex because men weigh three times as much as women.
In contrast, it is not easy for humans to distinguish according to size.
Prominent male genitals and female breasts help identify the opposite sex in creatures of similar size and shape, Taylor said.
Similarity in size, plus the convenience of the faceto-
Allowing sexual intercourse to be a vital part of social, communication, and invention and creation.
