Like the other apes and humans, gorillas cannot swim naturally, therefore they avoid large bodies of water and rivers.
mountain gorillas like other primates and humans are scared of water and some insects like caterpillars and reptiles like Chameleon. Gorillas like other apes including humans find it hard to swim naturally which prompts them to desist from expanse water masses (big water bodies) like Lakes and Rivers.
The tree-dwelling ancestors of apes had less opportunity to move on the ground. They thus developed alternative strategies to cross small rivers, wading in an upright position or using natural bridges. They lost the instinct to swim. Humans, who are closely related to the apes, also do not swim instinctively.
Most mammals are able to swim instinctively without training; a notable exception being the great apes. Humans are clearly able to become proficient swimmers with training; other great apes, however, have not been documented as swimmers beyond anecdotal reports.
In sum, if we define crying as tearful sobbing, then we know that humans are the only primates that cry. If we define crying as emitting vocalizations that co-occur with distressing situations, then we can conclude that most monkeys and apes cry, especially as infants.
For decades, monkeys' and apes' vocal anatomy has been blamed for their inability to reproduce human speech sounds, but a new study suggests macaque monkeys—and by extension, other primates—could indeed talk if they only possessed the brain wiring to do so.
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.
Due to the much larger evolutionary distance between humans and monkeys versus humans and chimpanzees, it is considered unlikely that true human-monkey hybrids could be brought to term.
Experts say the idea that a human can best a chimp in a fight is sorely mistaken. According to a 2017 study published in the journal PNAS, chimpanzees are 1.5 times stronger than a strapping human and contain about twice the amount of "fast-twitch" muscle fibers as we do.
Disease transmission. Transmission of diseases is a major concern for the viability of populations of wild primates: contact with humans (forest researchers, tourists …) tends to increase the contamination between species.

Certain reptiles such as chameleons and caterpillars are what are gorillas scared/afraid of. They are also afraid of water and will cross streams only if they can do so without getting wet, such as by crossing over fallen logs, and dislike rain.
Researchers have engineered two generations of monkeys with mutations in SHANK3, a top autism gene. The first generation shows traits reminiscent of the condition, according to a study published today in Nature1.
Monkeys, apes and other simians have nothing quite like our tears. They have tear ducts to help keep their eyes lubricated and clean. But they don't drain when they're sad. Chimps will scrunch up their faces and make noise when they're in distress, but they don't connect the tears and the wailing.
Researchers have published a study claiming that macaque monkeys have evolved to detect the threat of snakes. Published in the Proceedings of the National Academy of Sciences, the study points to the existence of neurons in the brain of the monkeys that selectively respond to snake images.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
The chimpanzee and bonobo are humans' closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species.
Animals that give birth to babies are called mammals. So, the animals, reproducing the babies of their own kind, by directly giving birth, are called mammals. For example, human beings are mammals. Cats, dogs, cows, horses, elephants, goats, pigs, lions, rats, squirrel etc.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
Humans have never stopped evolving and continue to do so today. Evolution is a slow process that takes many generations of reproduction to become evident. Because humans take so long to reproduce, it takes hundreds to thousands of years for changes in humans to become evident.
The briefest possible response would be to emphasize that evolution deals with common ancestors. It is not that humans descended from apes and that apes descended from monkeys; rather, humans and apes share a common ancestor, and it is more recent than the common ancestor they both share with monkeys.
The Smartest Ape Species Apart from Humans
Deemed the smartest apes on the planet, orangutans are exceptional creatures with expressive faces. Overall, the species considered most intelligent among the ape species, apart from humans, are orangutans.
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.
When confronted with uncertain or incomplete information in decision-making situations, monkeys and apes opt for either escaping the situation or seeking additional information. These responses have been interpreted as evidence of metacognitive abilities.
