Gorillas have been caught on camera for the first time performing face-to-face intercourse. Humans and bonobos were the only primates thought to mate in this manner. And while researchers have observed wild gorillas engaged in such an act, it had never been photographed.
“Researchers say that few primates mate in a face-to-face position, known technically as ventro-ventral copulation; most primate species copulate in what's known as the dorso-ventral position, with both animals facing in the same direction,” explained a statement from WCS.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
A pair of western lowland gorillas in Congo surprised scientists with a never before seen mating behavior. A pair of wild western lowland gorillas in Africa have surprised researchers by engaging in face-to-face mating, the Wildlife Conservation Society announced today.
The two species are evolutionarily too distant and their DNA is too dissimilar for a gorilla and a chimpanzee to produce offspring.
Humans and chimps have DNA that is 95 percent similar, and 99 percent of our DNA coding sequences are the same as well. However, humans have 23 pairs of chromosomes in our DNA, while chimps only have 22. The difference makes bearing healthy young difficult, and the offspring would be infertile.
Naturally, a human cannot impregnate a pig as there are many reproduction barriers between them. Naturally different species cannot breed as there are many reproduction barriers most importantly there are genetic barriers.
Macaques
Researchers believe that macaques have sex for pleasure because their sexual behavior is similar to humans. For example, macaques experience elevated heart rates and vaginal spasms when mating.

Different forms of self and partner genital stimulation have been observed in the animal kingdom. Oral sex has been observed throughout the animal kingdom, from dolphins to primates. Bonobos have been observed to transition from a simple demonstration of affection to non-penetrative genital stimulation.
Monkeys reproduce without human interference, so their offsprings' characteristics are determined by natural selection. Captive bred monkeys may be intentionally bred by their owners. A person who intentionally mates monkeys to produce babies is referred to as a monkey breeder.
“Small-bodied and vulnerable adolescent female Japanese macaques may prefer to engage in relatively safer sexual interactions with female monkey sexual partners in lieu of riskier sexual interactions with more aggressive male mates,” Gunst-Leca says, explaining that sometimes humping other animals is safer than hooking ...
There are documented cases of Soviet experiments in the 1920s where artificial insemination was attempted using female chimps and human sperm. However, none of these experiments resulted in a pregnancy, much less the birth of a 'humanzee'.
Male gorillas: Homosexual behaviour is observed very rarely in harem groups (occasionally during play between youngsters), but it is common in all-male groups.
Just like humans, monkeys have many different relationships when it comes to mating and reproduction practices. But how do monkeys mate? They can mate monogamously, have a harem, or practice polyandry.
Breastfeeding animals has also been practised, whether for perceived health reasons – such as to toughen the nipples and improve the flow of milk – or for religious and cultural purposes. A wide variety of animals have been used for this purpose, including puppies, kittens, piglets and monkeys.
Natural selection has meant that animal mothers reject the weaker offspring to prevent predation by other species and give longevity to their own, bolstering generations of animals to come. In large, wild mammals, litters are a lot smaller than in domestic animals like cats and dogs.
Roughly half of females reproduce in the group where they were born, resulting in the potential for them to reproduce with their fathers. However, the genetic analyses in this study found no evidence of father-daughter reproduction, although half siblings were observed to occasionally reproduce.
No, gorillas and chimpanzees cannot mate. The two species are evolutionarily too distant and their DNA is too dissimilar for a gorilla and a chimpanzee to produce offspring.
Mating in Gorillas
The dominant silverback mates with all females in the group as soon as they begin ovulation. The moment when a female gorilla is ready to mate is not evident physically like it is in chimpanzees. In most cases, it is the female who initiates the mating process as soon as she ready.
