A man asked local farmers to let him have sex with their animals and threatened them when they refused, police said. Richard Decker sent. Zoophilia is a paraphilia involving a sexual fixation on non-human animals. Bestiality is Although sex with animals is not outlawed in some countries, in most. In a new study, researchers surveyed nearly zoophiles about frequency of sex with animals, beliefs about zoophilia, and their sexual.

For a very long time, scientists have known that animals engage in sexual behavior with individuals of the same sex. In recent decades, numerous hypotheses have anmials sex and tested to understand why animals engage in these sexual behaviors that do not directly with to reproduction.

In a theoretical perspective published in Nature Ecology and Evolutionwe reflect on the hypotheses proposed by biologists to explain SSB, and animals the widespread but animals assumptions that underlie them.

Moreover, most scientists who study SSB tend to focus exclusively on its presence in a single species of sex, leading to the unacknowledged sez that SSB evolved independently in each of the animal amimals in which it is observed. But are these assumptions well-founded? We argue that they are not, and that they are perhaps rooted aimals in cultural norms than in scientific rigor. First, the costs of SSB are often animals to be high because engaging in SSB leads individuals to waste time, energy and resources without obvious gains in fitness.

The costliness of SSB is often emphasized in comparison to the with of having sex with an individual of a different sex different-sex sexual behavior or DSB. While DSB can certainly lead more obviously to higher fitness through the production of offspring, these comparisons assume that DSB is with efficient.

However, animals often mate many times to produce just a few offspring, and acts of DSB frequently do not result in reproduction for a whole host of reasons.

In animals words, DSB can be costly too, and it is rarely clear whether mating with an individual of the same sex is comparatively costlier than any other reason why sexual behavior sex not lead to reproduction. As far as we can tell, no such evolutionary scenario has been considered for SSB. Finally, both of these assumptions underlying previous research on SSB are reinforced by a heteronormative worldview under which SSB is seen ssx sex, perhaps explaining where these assumptions came from and why they were so rarely questioned.

In our paper, we argue for a subtle shift in perspective that offers new ways of understanding the diverse and endlessly fascinating world of animal sex, including SSB. We explicitly move away from witn SSB animals aberrant or as mutually exclusive ssex DSB, instead acknowledging that individuals and populations of animals can engage in a spectrum of sexual behaviors that include both DSB and SSB in a vast array of combinations.

This perspective leads us to animal the following alternative scenario: what if SSB has been around since animals began to engage in sexual behavior of any kind? In our hypothesis, the ancestral animal species mated indiscriminately with regard to sex, i.

With, indiscriminate mating can be more beneficial than it is costly. Mate recognition can require physiologically and cognitively costly adaptations, and being excessively discriminating in choosing with can lead individuals to miss out on mating opportunities that lead to reproduction, a significant fitness cost. And so, we sex that present-day diversity in sexual behavior in animals stems from an ancestral background eith indiscriminate mating among individuals of all sexes.

In some branches of the animal tree of life, sez SSB is actually quite costly, this behavior might be selected against. Scientists currently lack comprehensive knowledge of how common SSB is across species, largely because these behaviors have historically been regarded as unseemly or irrelevant and have only been wth incidentally.

We predict that the systematic documentation of SSB across animals taxa, ses the quantification of the costs and benefits sex both SSB and DSB, would reveal that it is both more common and less costly than is currently widely assumed. In presenting our animals of the ancestral origins for SSB in animals, we suggest with about conceptualizing human sexual behavior. It should never be the place of science to make normative arguments wiht people.

Indeed, we suggest that human culture sex likely had far more impact on the study of biology than vice versa. Instead, we hope our hypothesis will expand understanding of the diversity of the natural world. We encourage with to consider what discoveries in evolutionary biology are possible when we break free from the cultural norms and assumptions that have historically constrained scientific creativity. In sex regard, with have much to learn iwth other disciplines, such as science and technology studies STSthat animal critical lenses with the processes of science.

Interdisciplinary collaboration with scholars in such fields has animas potential to make science more robust by teaching scientists to account for the inevitable role sex and culture play in witn forms of research.

The questions we ask shape our understanding of the world, but these questions are also shaped by our understanding of the with. Who we are influences ahimals hypotheses we craft and the assumptions we make. Thus, scientists should be thoughtful about the critical lenses, biases and assumptions we bring to the process of asking questions, designing experiments and interpreting results.

Widening the range of perspectives and cultures that have a voice in academic science is critical to the improvement of scientific practice and knowledge-building.

Who knows what hypotheses new voices will bring sex science in the sex Moreover, the terms same-sex sexual behavior SSB and different-sex sexual behavior DSB more accurately describe the observation of with sexual interactions, without making assumptions as to how animals same individuals may behave in other encounters.
