Unbelievable! Scientist Discovers Gorillas Engaging in Lesbian S*x for the First Time Photo)

A scientist has made a shocking discovery in which he caught two gorillas engaging in lesbian s*x for what is believed to be the first case ever. 

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."
