標題[心得]動物的似同性戀行為發生的原因
時間Wed Jun 11 03:56:29 2008
動物似同性戀行為的原因:
1.展示權威與力量
a.忌妒
雄性動物為了搶奪雌性,把敵對的雄性動物從雌性動物趕走,並且騷弄對方生殖器
b.護幼
雌性動物撞到了某未成年動物,未成年動物的母親騷弄此入侵雌性動物的生殖器
2.紓解壓力
轉移注意力並紓解壓力
3.誤認同性為異性
動物界較低等的動物缺乏完善的異性辨識能力,把同性動物當成異性。

-- Explaining Seemingly "Homosexual" Animal Behavior
Bonobos are a typical example of this "borrowing." These primates from the
chimpanzee family engage in seemingly sexual behavior to express acceptance
and other affective states. Thus, Frans B. M. de Waal, who spent hundreds of
hours observing and filming bonobos, says:
There are two reasons to believe sexual activity is the bonobo's answer to
avoiding conflict.
First, anything, not just food, that arouses the interest of more than one
bonobo at a time tends to result in sexual contact. If two bonobos approach a
cardboard box thrown into their enclosure, they will briefly mount each other
before playing with the box. Such situations lead to squabbles in most other
species. But bonobos are quite tolerant, perhaps because they use sex to
divert attention and to diffuse tension.
Second, bonobo sex often occurs in aggressive contexts totally unrelated to
food. A
jealous male might chase another away from a female, after which the
two males reunite and engage in scrotal rubbing. Or after a female
hits a
juvenile, the latter's mother may lunge at the aggressor, an action that is
immediately followed by genital rubbing between the two adults.[7]
Like bonobos, other animals will mount another of the same sex and engage in
seemingly "homosexual" behavior, although their motivation may differ. Dogs,
for example, usually do so to express dominance. Cesar Ades, ethologist and
professor of psychology at the University of San Paulo, Brazil, explains,
"When two males mate, what is present is a
demonstration of power, not
sex."[8]
Jacque Lynn Schultz, ASPCA Animal Sciences Director of Special Projects,
explains further:
Usually, an un-neutered male dog will mount another male dog as a display of
social dominance--in other words, as a way of letting the other dog know
who's boss. While not as frequent, a female dog may mount for the same
reason.[9]
Dogs will also mount one another because of the vehemence of their purely
chemical reaction to the
smell of an estrus female:
Not surprisingly, the smell of a female dog in heat can instigate a frenzy of
mounting behaviors. Even other females who are not in heat will mount those
who are. Males will mount males who have just been with estrus females if
they still bear their scent.... And males who catch wind of the estrus odor
may mount the first thing (or unlucky person) they come into contact with.[10]
Other animals engage in seemingly "homosexual" behavior because they
fail to
identify the other sex properly.
The lower the species in the animal kingdom,
the more tenuous and difficult to detect are the differences between sexes,
leading to more frequent confusion.
