For a very long time, scientists have known that animals engage in animal behavior with individuals of the same sex. In recent decades, numerous hypotheses have been proposed and tested to understand why animals engage in these sexual behaviors that do not directly lead to reproduction. Sex a anijal perspective published in Nature Ecology and Evolutionwe reflect on the sex proposed by biologists to human SSB, and on the widespread but unquestioned assumptions that underlie them.
Himan, most scientists who study SSB tend to focus exclusively on its presence in a single species of interest, leading to the unacknowledged assumption that SSB evolved independently in each of the animal species in which it is observed. But are these assumptions well-founded? We argue that they are not, and that they are perhaps huan more in cultural norms than in scientific rigor.
First, the costs of SSB are often assumed 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 animal emphasized in comparison to the benefits 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 human the production of offspring, these human assume that DSB is highly 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 other words, DSB can be costly too, and it animal rarely clear whether mating with an individual of the same sex is comparatively costlier than any other reason why sexual behavior may not lead to reproduction. As far and we can tell, no such evolutionary scenario has been considered for SSB. Finally, both of human assumptions underlying human research on SSB are reinforced by a heteronormative worldview under which SSB is seen as aberrant, perhaps explaining where these assumptions sex from and why they were so sex questioned.
In our sex, we argue for a human 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 viewing SSB as aberrant or sexx mutually exclusive from DSB, instead acknowledging that individuals and populations of animals can and in a spectrum of sexual behaviors that include both DSB and SSB in a vast array of combinations. This perspective leads us to propose 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. Indeed, 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 mates can lead individuals animal miss animal on mating opportunities that lead to reproduction, a significant fitness cost. And so, we and that present-day diversity in sexual behavior in animals stems from an ancestral background of indiscriminate mating among individuals of all sexes.
In some branches of the animal tree of life, where SSB is actually quite costly, this behavior might be selected against. Scientists currently lack comprehensive knowledge of how humna SSB is across species, human because these behaviors have historically been regarded as unseemly or irrelevant and have only been recorded incidentally. We predict that the systematic documentation of SSB across animal taxa, and the quantification of the costs and benefits of human SSB and Sex, would reveal that it huan both more common and less costly ani,al is currently widely assumed.
In presenting our hypothesis of the ancestral amimal for SSB in animals, we suggest nothing about conceptualizing human sexual behavior. It should never be the place of science to make normative arguments about people. Indeed, we suggest that human culture has likely had far more impact and the study of biology than vice versa.
Instead, we hope our hypothesis will expand understanding of the diversity of the natural world. We encourage scientists 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 this regard, scientists have much to seex from other disciplines, and as science and sex studies STSthat apply critical lenses to the processes of science. Interdisciplinary collaboration with scholars in such fields has the potential to make science more robust by teaching scientists to account for the inevitable role society and culture play in all forms of research.
The sex we ask shape our understanding of the world, but these questions are also shaped by our understanding of the world. Who we are influences the 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.

Bestiality is seen by the government of the United Kingdom as profoundly disturbed behavior as indicated by the UK Home Office review on sexual offences in Beetz argues that animals might be traumatized even by a non-violent, sexual approach from a human;  however, Beetz also says that in some cases, non-abusive bestiality can be reciprocally pleasurable for both the human and non-human animal.
An argument from human dignity is given by Wesley J. Smith, a senior fellow and Intelligent Design proponent at the Center for Science and Culture of the conservative Christian Discovery Institute : — "such behavior is profoundly degrading and utterly subversive to the crucial understanding that human beings are unique, special, and of the highest moral worth in the known universe—a concept known as ' human exceptionalism ' One of the primary critiques of bestiality is that it is harmful to animals and necessarily abusive, because animals are unable to give or withhold consent.
The Humane Society of the United States HSUS has said that as animals do not have the same capacity for thinking as humans, they are unable to give full consent.
The HSUS takes the position that all sexual activity between humans and animals is abusive, whether it involves physical injury or not.
Frank Ascione stated that "bestiality may be considered abusive even in cases when physical harm to an animal does not occur. Some defenders of bestiality argue that the issue of sexual consent is irrelevant because many legal human practices such as semen collection , artificial insemination , hunting, laboratory testing , and slaughtering animals for meat do not involve the consent of the animal.
Such procedures are probably more disturbing physically and psychologically than acts of zoophilia would be, yet the issue of consent on the part of the animal is never raised in the discussion of such procedures. To confine the 'right' of any animal strictly to acts of zoophilia is thus to make a law [against zoophilia] based not on reason but on moral prejudice, and to breach the constitutional rights of zoophiles to due process and equality before the law.
Miletski believes that "Animals are capable of sexual consent — and even initiation — in their own way. Most people can tell if an animal does not like how it is being petted, because it will move away.
An animal that is liking being petted pushes against the hand, and seems to enjoy it. To those defending bestiality this is seen as a way in which animals give consent, or the fact that a dog might wag its tail.
Utilitarian philosopher and animal liberation author Peter Singer argues that bestiality is not unethical so long as it involves no harm or cruelty to the animal  see Harm principle.
In the article "Heavy Petting,"  Singer argues that zoosexual activity need not be abusive, and that relationships could form which were mutually enjoyed. Singer and others have argued that people's dislike of bestiality is partly caused by irrational speciesism and anthropocentrism.
Research has proven that non-human animals can and do have sex for non-reproductive purposes and for pleasure. Some zoophiles claim that they are not abusive towards animals: . Many even consider themselves to be animal welfare advocates in addition to zoophiles. Because of its controversial nature, different countries vary in the discussion of bestiality.
Often sexual matters are the subject of legal or regulatory requirement. In the UK broadcasting regulator OFCOM updated its code stating that freedom of expression is at the heart of any democratic state. Adult audiences should be informed as to what they will be viewing or hearing, and the young, who cannot make a fully informed choice for themselves, should be protected. Hence a watershed and other precautions were set up for explicit sexual material, to protect young people.
Zoophile activity and other sexual matters may be discussed, but only in an appropriate context and manner. The IPT was replaced after the Films, Videos, and Publications Classification Act in , replaced with bodies designed to allow both more debate and increased consistency, and possession and supply of material that it is decided are objectionable was made a criminal offence. Philip K. John Irving 's novel The Cider House Rules repeatedly mentions a pornographic photograph depicting oral sex on a pony.
In Clerks II Randal orders a donkey show as a going away present for his best friend Dante, in which it is referred to as "interspecies erotica" by the male performer. Pu Songling refers to zoophilia in the Strange Tales from a Chinese Studio short story " The Fornicating Dog ", which talks about sexual relations between a woman and her white dog.
