we started / re-quote this article because it is science
that everyone should have some knowledge about it
a science fact that break through traditional blind corners of man made short sighted beliefs

human is undeniable a type of animal
homosexuality is quite common
many animals solve conflicts by practicing same gender sex
homosexual behaviour has been observed in 1,500 animal species

“one fundamental premise in social debates has been that homosexuality is unnatural
this premise is wrong
homosexuality is both common and highly essential in the lives of a number of species”
explains Petter Boeckman who is the academic advisor for the “Against Nature’s Order?” exhibition
Petter Boeckman of the Norwegian Natural History Museum of University of Oslo

the most well-known homosexual animal is the dwarf chimpanzee
one of humanity’s closes relatives
the entire species is bisexual
sex plays an conspicuous role in all their activities and takes the focus away from violence
which is the most typical method of solving conflicts among primates and many other animals

“sex among dwarf chimpanzees is in fact the business of the whole family
and the cute little ones often lend a helping hand when they engage in oral sex with each other”

lions are also homosexual
male lions often band together with their brothers to lead the pride
to ensure loyalty
they strengthen the bonds by often having sex with each other

homosexuality is also quite common among dolphins and killer whales
the pairing of males and females is fleeting
while between males, a pair can stay together for years
homosexual sex between different species is not unusual either
meetings between different dolphin species can be quite violent
but the tension is often broken by a “sex orgy”

homosexuality is a social phenomenon and is most widespread among animals
with a complex herd life

among the apes it is the females that create the continuity within the group
the social network is maintained not only by sharing food and the child rearing but
also by having sex
among many of the female apes the sex organs swell up
so they rub their abdomens against each other
explains Petter Bockman and points out that animals have sex because they have the desire to
just like we humans

“we’re talking about everything from mammals to crabs and worms
the actual number is of course much higher
among some animals homosexual behaviour is rare
some having sex with the same gender only a part of their life
while other animals such as the dwarf chimpanzee
homosexuality is practiced throughout their lives”

animals that live a completely homosexual life can also be found
this occurs especially among birds that will pair with one partner for life
which is the case with geese and ducks
four to five percent of the couples are homosexual
single females will lay eggs in a homosexual pair’s nest
it has been observed
that the homosexual couple are often better at raising the young than heterosexual couples

when you see a colony of black-headed gulls
you can be sure that almost every tenth pair is lesbian
the females have no problems with being impregnated
although according to Petter Boeckman they cannot be defined as bisexual

“if a female has sex with a male one time
but thousands of times with another female
is she bisexual or homosexual ?
this is the same way to have children is not unknown among homosexual people”

indeed
there is a number of animals in which homosexual behaviour has never been observed
such as many insects, passerine birds and small mammals

“to turn the approach on its head:
no species has been found in which homosexual behaviour has not been shown to exist
with the exception of species that never have sex at all, such as sea urchins and aphis
moreover, a part of the animal kingdom is hermaphroditic, truly bisexual
for them, homosexuality is not an issue”

Petter Bockman regrets that there is too little research about homosexuality among animals

“the theme has long been taboo
the problem is that researchers have not seen for themselves that the phenomenon exists
or they have been confused when observing homosexual behaviour
or that they are fearful of being ridiculed by their colleagues
many therefore overlook the abundance of material that is found
many researchers have described homosexuality as something altogether different from sex
they must realise that animals can have sex with who they will
when they will and without consideration to a researcher’s ethical principles”

one example of overlooking behaviour noted by Petter Bockman
is a description of mating among giraffes
when nine out of ten pairings occur between males

“every male that sniffed a female was reported as sex
while anal intercourse with orgasm between males was only “revolving around” dominance
competition or greetings
