Female hyenas evolved false tintin only to maintain the strength of the matrilineal hierarchy

author:The entanglement of science

Hyenas are a social animal living in the African savannah, and unlike the gregarious social system of lions, hyenas live in groups of matriarchal social systems, they often flock when they go out to forage, and when they encounter dead animal carcasses, they will flock up, and sometimes even snatch the prey captured by lions from the lion's mouth, and they rely on a developed sense of smell and strong jaw teeth to feed on carrion. Female hyenas, on the other hand, weigh heavier than males and are stronger than male hyenas. Hyenas live in a strict hierarchy, and only the strongest female hyenas can be the leader and have the power to dominate the status of the dog.

hyena

Male hyenas are not even as senior in the group as the cubs they give birth to. What is even more incredible is that because the strong body needs more male hormone secretion, the female hyena even grows a "male genitalia" that is difficult to distinguish between true and false, which is actually a female hyena due to the excessive exuberance of male hormones so that the yin di grows under hormone stimulation to look like male genital organs. And it is this organ, which is nearly 20 centimeters long, which is more intimidating in social life, and seems to express that I can not only have the same organs as you (males), which further strengthens the position of females in the group.

Of course, female hyenas cannot shock other individuals with fake genitalia alone. Due to the special reproductive structure of female hyenas, they also hold the power to mate. Most of the female genitalia of most creatures in the world are between the buttocks, and it is easy to obtain male mating during estrus, but the reproductive organs of female hyenas are on the stomach, that is, they are well protected by it, unless it has its own willingness to mate, otherwise male hyenas cannot obtain mating rights.

In this way, female hyenas rely on a body that is 10% stronger than male hyenas, as well as self-control mating power, allowing them to successfully become a matrilineal social society. Of course, there is not only one female hyena in a group, but other female hyenas have a lower status, and even other female hyenas have lower offspring than the chief's cubs. Therefore, other female hyenas are also responsible for taking care of the chief's cubs. But they all have a higher status than the male hyenas in the group.

Hyenas prey

Every time when foraging, the "female leader" will generally get the most meat of the captured prey, the freshest and largest piece of meat, in addition, the hyena is not strict everything will be collectively dispatched, they often form a group circle, there will be considerable freedom, and even often alone, to catch the prey alone, to enjoy the prey alone. Many members of the group are separated from each other at a great time. However, as soon as they reunite, they will do what the group should do together as a member of the group, so as to show their gregariousness. It seems like joining a gang. And when female hyenas and male hyenas meet together, they will also have "lady first", let the female hyena walk in front, and the prey obtained will be given to the female to eat.

The incredible social life of hyenas, with its tightness and rule-making beyond imagination, seems to be like the matriarchal clans of early humans. This may be the unique way of life of different species according to the laws of nature.
