This might sound unbelievable. However, Associate Professor Dr.
Cyril Grueter, a primate expert from the University of Western
Australia, has made a shocking discovery while examining the feeding
patterns of gorillas in Rwanda - he caught two female gorillas engaging
in s*x act.
The report seems to be the first occurrence of same-sex passion among female gorillas, The Mirror reports.
He told Daily Mail Australia : "Instead of seeing aggression between females over food we saw them engaging in sexual behaviour which was quite surprising."
According to Dr. Grueter, a majority of the female gorillas usually
turn to each other for sexual stimulation when rejected by males and
obviously derived sexual pleasure from the act.
Of the 22 female gorillas examined from 2008 to 2010, 18 engaged in sexual activity with other females, including 'genital rubbing,' 'genital closeness' and mating calls during intercourse.
Speaking further, Dr. Grueter explained that the behaviour of the
female apes was purely motivated by sexual arousal rather than
attraction, and they were equally aroused by males and females.
The study, published in the journal PLOS ONE states that: "Twelve
out of 43 homosexual events (28 per cent) involved at least one female
that was also involved in a heterosexual act on the
same/preceding/following day."
He told Daily Mail Australia: "'Its not necessarily that they have same-sex orientation, it’s purely sexual behaviour." He also observed that while engaging in the same-s*x intercourse, the gorillas often hide in dense vegetation.
He added: "Gorillas are closely linked to humans and
we thought by looking at this behaviour we could learn a little more
about our own evolution."
