Despite the chimpanzees being the closest extant relatives of humans, 15% of the human genome was found to be more like that of the gorilla.

IGCP also works with partners to undertake mountain gorilla censuses every 5-10 years, so as to monitor population size and health.

Conversely, coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants.

Gorillas are strong, but in this site seems to be a lot of claims, but no sources for people to check. Both gorilla species have been decreasing in numbers for decades, and a 2010 United Nations report suggests that they may disappear from large parts of the Congo Basin by the mid-2020s. Severe aggression is rare in stable groups, but when two mountain gorilla groups meet the two silverbacks can sometimes engage in a fight to the death, using their canines to cause deep, gaping injuries.In their natural habitat, they face various threats, such as predators, diseases, and environmental factors, that can significantly impact their lifespan.
