But what does unnatural really mean? The definition of the term is something that goes against natural or human laws, especially in relation to morality. A male is born with a predisposition to mate with a female, since the aim is reproduction of the species. This is something determined by nature. But is it really like this? In the animal kingdom there are many examples of homosexuality that completely dismantle the theories that associate these practices with a purely cognitive trait of human beings.
In fact, in some species, homosexuality represents an evolutionary advantage. Inzoologist Konrad Lorenz published a study in which Species that have homosexuality in christianity studied the behaviour of 1, animal species. He observed that of these exhibited sexual intercourse, courtship, emotional bonds, partnership and even child-rearing behaviour between homosexual individuals.
From primates to intestinal parasites. A decade later, a study conducted by Dr. These behaviours were different for each species, but in most cases they were an advantageous, evolutionary mechanism. In other species, such as fruit flies and insects in general, homosexuality occurs because of their inability to differentiate between sexes. Geese are monogamous animals. They spend their lives with a single mate and only look for another if the first one dies.
The biologist Kurt Kotrschalfollowing on from the studies of Konrad Lorenz, has devoted many years to studying these animals. His research supports the idea that homosexuality is useful for the species. InLorenz stated that male mates are more likely to occupy a higher level within geese colonies. This allows them to fertilise solitary females, while continuing with their same sex partners.
This is Species that have homosexuality in christianity of the theories that reports the evolutionary advantage of homosexuality, but it is not the only one. These studies explore the idea of homosexual behaviour as an evolutionary response to environmental changes.
The environment is what determines these changes, driving species to change their sexual and affective behaviours. In the case of American bisonpolecats or elephantsboth males and females have been observed courting and mating with others the same sex.
In the case of giraffes9 out of 10 couplings occur between males. As for birds, all species that form parental relationships do so, to a greater or lesser extent, with members of the same sex. As many as a quarter of black swans are homosexual. Penguins have even struck up same-sex relationships in zoos in different parts of the world.
It is interesting to note how the strong rejection of homosexuality by most societies throughout history has disadvantaged the emergence of a very different reality. A reality in which relationships between individuals of the same sex occur in all species and are part of their evolutionary development. In most cases, studies on this subject were avoided for fear of rejection by the scientific community and the wider social context marked by machismo and homophobia.
Even today, it remains a taboo subject in many parts of the world where homosexuality is forbidden or even punishable by death.
