Non-reproductive sexual behavior consists of sexual activities animals participate in that do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals , recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Observed non-procreative sexual activities include non-copulatory mounting without penetration, or by the female , oral sex, genital stimulation, anal stimulation, interspecies mating, and acts of affection. Lions are known to engage in sex to create bonds and interact with each other. Lions live in a social group known as a pride that consists of 2—18 females and 1—7 males. The females found in these prides were born into the pride.

Non-reproductive sexual behavior in animals - Wikipedia

Scientists may have caught two animals from completely different species having consensual sex for the first time. Sex between animals of different kinds has been reported across a wide range of the animal kingdom. Those reports of very different animals are usually seen between animals that are born and bred in captivity. Most of those examples also constitute a kind of sexual harassment.

The primal scene in cross-species and cross-cultural perspectives

Last week, scientists published research on monkeys mounting deer in a sexual way. This interaction may seem pointless from an evolutionary point of view, but as it turns out, the striking behavior is fairly common in the animal kingdom. Many people have seen this exact phenomenon at play with non-neutered male dogs and cats, ducks, sheep and bulls. They are often willing to copulate with any female, male, animal, leg, or inanimate object that can be physically mounted. Dead or alive, it doesn't matter.

Humans started having sex with Denisovans and Neanderthals a very long time ago, research suggests. Computer analysis of human evolutionary history has shed light on a discrepancy between genetic evidence from fossils excavated from Sima de los Huesos in Spain and a model developed by the same researchers. However, a new study published in Science Advances suggests they separated much earlier, implying Neanderthals were already distinct from Denisovans by , years ago. The new model supports the view that modern humans and their ancestors expanded from Africa into Eurasia only three times — 1. Large-brained hominins first appeared in Europe and Asia about , years ago in the period known as the middle Pleistocene — an important milestone for early humans.
