This is normal, because you will probably grow up like Oden, and the evolution of gorillas is not complete. Traditionally, gorillas themselves are a species and divided into three subspecies: Western Lowland gorilla (G. g. gorilla), eastern lowland gorilla (G. g. graueri), and mountain gorilla (G. g. beringei). In recent years, some scholars have divided the genus Gorilla into two species: western gorilla (G. gorilla) and eastern gorilla (G. beringei); western gorilla is divided into two subspecies: western lowland gorilla (Gorilla gorilla gorilla) ) and Cross River gorilla (Gorilla gorilla diehli), the eastern gorilla is also divided into two subspecies: the eastern lowland gorilla (Gorilla beringei graueri) and the mountain gorilla (Gorilla beringei beringei). Some even believe there are five subspecies of gorillas (the mountain gorillas of the Bwindi Mountains). So far these debates have been inconclusive. Kinship relationships among various gorilla groups remain the subject of research.

Gorillas are diurnal forest animals. Lowland gorillas prefer tropical rainforests, while mountain gorillas prefer mountain forests. Mountain gorillas mainly live on the ground, while lowland gorillas live mainly in trees. Even heavy males often climb 20-meter-high trees in search of food. Gorillas make fists with their forelimbs to support their body while walking. This walking method is called fist walking. In this way, they walk on all fours with their forelimbs supported on the middle segments of their fingers. They use leaves to make nests when they sleep at night, and they make new nests every night. The nest-building process usually takes no more than five minutes. Mountain gorillas generally have their dens on the ground, while lowland gorillas' dens are mainly in trees.

Gorilla groups are very flexible, and a group will often separate while looking for food. Unlike other primates, both male and female gorillas may leave their natal group to join other groups. Male animals first leave the group where they were born after they are about 11 years old. After that, they live alone or with other male animals. They can attract females to form new herds after two to five years.

Generally a group can last for a long time. Sometimes a fight breaks out within the group for leadership. The challenge may be a young male within the group or an outside male. The challenged male will scream, beat its chest, break branches, and then charge towards the challenging male. If the challenger defeats the original leader, it will usually kill its predecessor's cubs. The reason may be that the nursing female does not mate, but she is able to mate again shortly after the cub is killed.

If the original leading male animal in a group dies of illness or accident, the group is likely to split, and the members of the group will look for other groups.

The territoriality of gorillas is not very obvious. Many groups search for food in the same area, although they generally avoid direct contact. Since gorillas' main diet is leaves, they have relatively short paths to find food. The reason is that firstly, there are many leaves in the area, and secondly, the nutritional content of the leaves is relatively low, so they have to rest frequently.

Gorillas have different calls. They use these different calls to locate members of their own group and other groups, as well as to signal threats. Famous for chest-tapping. Not only the older males bang their chests, but all gorillas bang their chests. It is estimated that this behavior is used to indicate one's position or to welcome the other party.
