Τα ζώα μπορεί να είναι γκέι;
Ναι, απαντούν οι επιστήμονες του Πανεπιστημίου της
Χαβάης μετά από μελέτη μιας αποικίας θαλάσσιων πουλιών.
Η έρευνά τους έδειξε ότι το 33% των ζευγαριών που
υπήρχαν σε αυτή την αποικία ήταν δύο θηλυκά πτηνά.
Αφού ζευγάρωναν με αρσενικά, τα πτηνά αυτά
φωλιάζουν με τις συντρόφους τους και μεγάλωναν μαζί τα μικρά τους.
Μάλιστα, ορισμένοι βιολόγοι ισχυρίζονται ότι έχουν
εντοπίσει ομοφυλοφιλική συμπεριφορά σε περισσότερα από 1.500 διαφορετικά είδη.
Can animals be gay?
It is the question baffling wildlife experts across
the globe – can animals be homosexual?
By Nick Collins (telegraph.co.uk)
According to Darwin, the
sexual impulses of animals are designed to cause reproduction, and are
therefore necessarily heterosexual.
But new research suggests
homosexual animals – often dismissed by biologists as the exceptions that prove
the rule – may be more common than previously thought.
A study of an albatross colony
at the University of Hawaii revealed that one third of the 'couples', who
commit to each other for life, consist of two females.
After mating with males, the
pairs of females nest with their 'wives' and incubate their eggs together .
The exceptional trend had
previously gone unnoticed because male and female albatrosses are virtually
indistinguishable from each other.
Some biologists claim 'gay'
animal behaviour has been spotted in 1,500 different species, and reliably
recorded in a third of these cases.
According to research, about a
fifth of captive king penguins are gay, while it is common for male black swans
to raise cygnets as a couple – possibly to provide better protection.
Male dung flies, meanwhile,
appear to mate with other males with the aim of exhausting them and thereby
reducing the competition for females.
Behaviour that appears to be
gay has been observed in giraffes, butterflies, koalas, dolphins, octopuses and
sheep, to name but a few.
Petter Bockman, an expert on
homosexuality in animals from the University of Oslo, told the Daily
Mail: "If you ask: 'Can animals be gay?' the short answer is: 'Yes.'
'Gay' is a human word, however, so we prefer to use the word 'homosexual' for
animals.
"Sexuality is not just
about making babies, it is also about making the flock work. For some animals,
homosexuality is normal flock behaviour."
Scientists are divided over
the significance of such findings. Bruce Bahemihl, a gay biologist at the
University of Wisconsin, said researchers assume animals are not gay because of
a "heterosexual bias".
Others argue that animals are
programmed to be heterosexual in order to survive. Dr Antonio Pardo, professor
of bioethics at the University of Navarre, Spain, said: "Homosexuality
does not exist in animals.
"Nevertheless, the
interaction of other instincts, such as dominance, can result in behaviour that
appears to be homosexual."
Professor Paul Harvey, head of
zoology at the University of Oxford, said it is wrong to use examples of
animals to support arguments over whether it is 'natural' to be gay.
He said: "It is a huge
mistake to think studying homosexuality in animals gives us a greater
understanding of human behaviour.
"If you want to know why
humans are gay, ask a human."
